AH! News


Tuesday June 18 2008 - 13.00

Just a short note that we have found again a limited quantity of NOS Siemens 288CC tubes ánd a batch of Tesla E88CC Gold Pin / Red Point tubes.

The SuperTubeClock is still growing strong(er). Hi-Fi World measured lowest jitter specs ever on the version of our SuperTubeClock as installed in our PrimaLuna PL8 cd-player. The SuperTubeClock can be easily installed in our Njoe Tjoeb 4000 cd-player and if you have a Reference we can even install 3 clocks .... In other cd-players, sacd-players, dvd-players we can also install our SuperTubeClocks, but we might need more time to find out how and where we can install.

Tuesday December 18 2007 - 21.00

Merry Christmas and a Happy New Year to all. Hopefully 2008 will only bring good things.

We have just finished the design of SuperTubeClock Version 3.0 and look forward to get these available early 2008. In a relatively short time we have almost sold our first batch of 1,000 pieces which we consider as being quite good, due to the fact it is a kind of "special" product.

Saturday November 04 2006 - 14.30

I don't want to repeat myself, certainly as this section is the "NEWS"-section, but the results of our SuperTubeClock are so amazingly well-received by ALL customers who tried it in a variety of cd-player- brands and models, that simply HAVE to -kind of- repeat myself. If -experienced- customers tell us that the cd-player seems to be / sounds to be re-invented, what more can you say? Next to a better cd-player it brings also back the "old-fashioned" (??) feeling of fun you have as a supplier AND as a customer if you notice the great improvement a simple-looking (remember we worked 3 years on this ...) circuit can do to your sound. Customers that get their clock installed during the day on friday, on friday-evening already email us how "rocking good" the new cd-player sounds and on saturday-morning email again to tell they have been rocking again for a few hours .....  

Saturday October 07 2006 - 14.30

You might be amazed it took so long before we got new NEWS!! Same here ... It took us since 2003 to get a dedicated Clock we always wanted to have for our AH! Njoe Tjoeb 4000. We have it now. And it is not only a dedicated Clock for our AH! Njoe Tjoeb 4000, it is a Clock for every player out there. It's an universal Clock and ... it comes with a heart of "tube" which is unique in the world. It’s the SuperTubeClock!!! We have AH! Njoe Tjoeb players, Copland players, EC players, Marantz players, Krell players as beta-testers. All having a better digital life now ....

Carnaval is on it's way in the south of The Netherlands! This means that:

DÉ HIFIWINKEL in
Eindhoven will be closed for a full week starting monday February 23 till saturday February 28. Everybody will be back on tuesday March 2.

Next to that it seems that Rob Wilms of  DÉ HIFIWINKEL in Beek-Ubbergen (
Nijmegen) needs a holiday and he will be closed from march 22 untill march 27.

Wednesday January 21 2004 - 03.00

Back from the U.$$.A.!! Despite low $, this country is still f*****g expensive! How about a simple espresso coffee for $ 3.50 excluding 8% tax, excluding 20% tip. In real money that is > Hfl 8,-. Sorry, I still calculate now and than in Dutch Guilders to better realise the (non)"value"! Anyway, Las Vegas was fun as always and as it should be. Despite the high security on every corner of the street, the airports, the hotels etc.

It was the show with a number of positive people as the sales during the last months of 2003 were good for them. Others were not so positive, or better, were negative or even disappeared from the market .... I don't have to mention brands, but one of the Leaders of the Gang is at least for 12 months out of the market. Why? Simply because it was not profitable and the big, big parent-company wants to see PROFITS!! As simple as that. The other Leader of the Gang, Krell, was feeling good at the show, as they took on quite a bit of new US dealers ... Wadia also seems to be back with a range of new products. The man Mark Levinson, now from RedRose, was suffering again ... I think the man is a genius, but knowing him personally very well and having seen what he did the last 30 years, I think the best would be to continue to write about female orgasmes ... What I hear is that people seem to get tired to be confronted with his coming-up and going-down adventures (no, this is not referring to his latest book ...). Read what Enjoy-the-Music, a leading audiophile website in U.S.A. wrote: "What happens when you lose a company with your name, another company you start up goes under shortly after you leave (thereby making any warranty work null and void), and then you dare to start yet another company that stirred some controversy as to the true origins of the electronics, then have an interesting divorce, then followed by... 
Well, read it for yourself folks."

 

 

And further was Las Vegas full of nice sunny weater between 15 and 20 degrees Celcius. Krell was completing the ShowCase Set with their new DVD-player. Transparent was showing the full new line of their MM-version cables. Kevin Deal was partying backstage with Tom Jones his Enjoy-the-Music Award for our AH! Njoe Tjoeb 4000 cd-player as being the best digital product of the year 2003! Sonus Faber was proudly showing the new Stradivari loudspeakers. Vienna Acoustics was getting full attention for their highly superdesigned aluminium home-cinema range of loudspeakers. Conrad-Johnson was proudly pointing at their beautiful reference tube-preamplifier. Our PrimaLuna brand will start distribution in Japan with DotLabo and with Upscale Audio in USA. Samples have been received with full enthousiasme. Kevin: "I am thrilled, no, better: I am over-thrilled with the quality of build and musicality. It's deadsilent (on high-efficiency horn-loudspeakers) as for hum and hiss and superdynamic on my favorite noise: music!. Thank You!"

Friday January 2 2004 - 21.00

AH!appy New Year to all of you! First new review, or better: translation, is from Ferry Kremers. Again, our PrimaLuna ProLogue One is the subject of his story. Click here and Enjoy the Music from his words.

AH! Njoe Tjoeb 4000
                              
"digital product of the year!!"

I only repeat the words of one of our AH! Njoe Tjoeb 4000 customers who wrote in the hifi-notes.com guestbook: http://www.enjoythemusic.com/magazine/equipment/0104/bestof2003.htm Again praise for the Tjoep-cdp. Does this never stop??? ;-) Jules. Well, we hope not ... Click to see what Jules saw enjoythemusic.com (and thanks for reporting!!).

No long stories today from my side. Just a mentioning of the arrival of the Dutch version of Stefan Krawczyk's PrimaLuna ProLogue One review. Click here to read his review.

Monday December 22 2003 - 16.00

Almost Christmas and still tons of work to do before we can sit/lay down and rest. I wish all the people all over the world what they wish us and hope all of you have a good time and enter the New Year in Good Health! Merry Christmas and a Happy New Year!

Wednesday December 3 2003 - 01.00

Vic Diederen just translated Rob Wilms' review of the PrimaLuna ProLogue One into English and he is on his way of delivering more translations. Keep an eye on this page to see reviews in different languages. Another PrimaLuna ProLogue One review (in Dutch language) is here from HifiShop customer Rob Leijsen. What else? Well, we amazed ourselves with very simple things ... Since long I could never understand why high-quality cables were "highly recommended" while for example inside the speaker just very "simple" wiring was found. I remember one speaker-manufacturer (Wilson Audio) being very "proud" to use better-than-average cable: Monster. I always wondered what the effect would be if inside and outside the same high-quality cable was used. We listened to our first prototype AH! TjoeLipS loudspeakers with "standard" internal wiring. The speaker performed very well, without any question and visitors in our shop were attracted by the sound and asked "What's that"? But what happened after we replaced the internal wiring with our AH! LS Direkt KB 8 loudspeakercable is simply unbelievable! We have a NO-SPEAKER-IS-THERE-SOUNDSTAGE!!! Lots of air, transparency, ease. True-size imaging and no speakers!!! We are still fine-tuning as we want to get the maximum out of this design. But it reminds me of the time that Dan D'Agostino took me by the arm during a CES-Show in Las vegas, brought me to the room of Wilson Audio and pushed me into a sofa to listen to the Watt/Puppy 2/3. At that time I didn't know more to say than "I want to have this, I want to distribute this", got the price from Dave Wilson personally (yep, at that time that was still possible ...) and remember that later during the night I could not sleep as I had no idea if I could pay the order I just placed and if I could sell what I just ordered. Anyway, at that time that feeling was good! And it's nice to have that same kind of feeling with our AH! TjoeLipS. I think these speakers are sensational. Other people talk about it as Wutt/Pappies. Well, whatever. I know we are having here a sensational speaker for a sensational price .... Euro 1750,- a pair!! we hope. Wait for the dealers, distributors who ask to double the price so they will make more money!! No way! This is AH! Give you far more value than anyone else. You want to pay double? No problem. Visit another "family" and you will get another (even less-tweaked) version of this "flower" of music and joy for a more-than-double retailprice .... Let me see if my pictures show up good enough on this page to make you see the differences and non-differences between tulips, roses, lilies etc.

Just back from Rome after having visited the AUDIA friends. First we went to visit their neat and well-organized design-studio. Massimiliano and Andreia explained how they work. Design and prototyping is done in-home. After a protoype is accepted for production, Audia organizes the flow of components which are all measured and selected at their premises. The selected parts are used to send to a Class A1 board-manufacturer who returnes the tested boards to Audia. At Audia the boards are tested again and than the assembly of the final product starts. Once the final product is assembled a series of tests are run again. Than follows a burn-in period after which again the final product is tested before it is packed in the wooden Audia crates. Quite simple but very beautiful! In the days after, during our visits to Roma-town, we noticed again that the Italians have it in their fingers: design, craftmanship, music, beauty etc.

How time flies! I noticed that
Stereophile magazine, published the AH! Njoe Tjoeb 4000 review of last month, in their archives. The advantage of that is that we can link you to the Stereophile review of the AH! Njoe Tjoeb 4000 from here! Yes, we are proud on the fact that Stereophile has spent so much time on the AH! Njoe Tjoeb 4000. 

Tuesday November 19 2003 - 14.00

Marcel van Overbeek spent his weekend with the AH! Black TjoeLipS (Marcel talks about 2LipS) and the new Copland CSA-29 integrated amplifier. The Copland CSA-29 is already available, while the AH! Black TjoeLipS speakers are on the way for delivery. We urgently wait for the next prototypes. The design of the stands for the AH! Black TjoeLipS speakers is done and first prototypes are being made right now. I was updated today on the AH! phonoboard and I can tell you, 2004 is gonna be a beautiful year. Marcel Croese is spoiling me by giving me all I want. Be patient. Click here for Marcel van Overbeek's review of the Copland CSA-29. 

Tuesday November 11 2003 - 10.00

ATTENTION!! November 29 2003, The Hifishop in Tilburg will be closed! Please make a note of that if you intend to go and visit Koos without having made an appointment.

Tuesday September 30 2003 - 18.00

Marcel van Overbeek safely returned from London Heathrow Hifi Show. Although this show did not get a lot of realtime airplay from Dutch and US websites (as far as I could find out), it seems it was very well visited. Icon Audio's room was simply too small as almost all the time, it was overloaded with visitors. Not only one-time visitors but also returning visitors bringing other visitors in to let them see and hear the Icon Audio and AH! products. Marcel brought and demonstrated from AH! the Tjoeb 66 amplifier, the new MM/MC phono-stage (without tubes!!) and the new LSDouble Direkt KB8 loudspeakercables. Overall results were very fine, as was mentioned by most visitors. Next year we will certainly be back with certainly more products. Thanks to Marcel and Icon Audio for spreading the AH! news!

Thursday September 25 2003 - 18.00

Marcel van Overbeek safely arrived in London to assist Icon Audio during the Heathrow Hifi News Show. So if you happen to be there have a look, listen and chat with him. He took the AH! Tjoeb 66 integrated amplifier, the new AH! (non-tube) mm/mc phono-amplifier and the AH! LSdouble Direkt KB8 loudspeakercables.

Monday August 25 19 2003 - 12.00

During my vacation I have worked less than I wanted, but still came up with some ideas. One idea was about the fact that people interested in AH! products but living in a country without a local AH! representative, are facing high transportationcosts if they order some of our products. Besides that, WE loose a lot of money if we get the payment with VISA. So I came up with the following: why not accept payment by banktransfer instead of VISA and ship at a much lower rate or even free?

So we decided:

Shipping from now on is FREE (
Europe) or subsidized (elsewhere)  if no local AH! representative is available and if the goods are prepaid by banktransfer (or in cash with a registered letter if you prefer that method). Decca arms are excluded from this as these are already almost for free!! 

Monday May 19 2003 - 12.00

Some further technical information was added. Apicture with the TjoUpsampler connections and how to deal with the TjoUpsampler's LongLegs and what to do if you want to use 6N1P tubes.

Saturday April 26 2003 - 12.00

Hallo Germany! Marcel van Overbeek will be showing and discussing AH! products during the Frankfurt High End Show on Thursday May 29, Friday May 30, Saturday May 31 and Sunday June 1. This year we will start off together with SSC-Akcept Audio our OEM-supplier for our AH! shelves and pucks (TjoebSjoes!!).

And next ... I have to announce that we have to go back in time for the Siemens E288CC prices. Our stock becomes very, very limited and we cannot find quantities, whatever sources we have tried. New price of
May 1 2003, is going to be Euro 250,- per pair. Sorry about that. We also have to announce that from May 1, 2003, the new price for the AH! TjoUpsampler will be EURO 350,-. That effects also the price of the AH!  Njoe Tjoeb Reference 4000 which will become Euro 1300,-. We are sorry about that, still we feel that it is very competitive with other 24/192 KHz dac-upsamplers in the market which are offered at double or triple prices ... Please check complete list on this site for current prices of all items.

Wednesday February 12 2003 - 20.00

Some simple instructions were added to the technical page for upgrading the headphone-output signal.

Monday December 30 2002 - 17.00

The growth and evolution of the audio industry since World War II has been astonishing. The speed of technological innovation, from portable radios to MP3 players, has been matched only by the proliferation of designs created for these icons of contemporary life. Furniture-style radiogram consoles have given way to sleek metallic exteriors, but audio equipment remains one of the ultimate design statements, reflecting popular culture, consumer aspirations and new developments in sound and engineering.

This book traces the development of audio design by decade, from the LP record, the birth of hi-fi and the first transistors in the 1950s, through the Japanese hi-fi boom of the 60s and 70s, the CD and the Walkman in the 80s, to the MP3 and DVD players of today. A specification is provided for each piece, along with a history of the design and its place in the development of both the audio industry and contemporary music. In addition, special features are included in each chapter on the music and culture of the time, highlighting the ongoing relationship between hi-fi design and popular culture. A wide range of high-quality audio design is gathered together, including work by major figures such as Dieter Rams, Marco Zanuso and Philippe Starck, and each piece of equipment is illustrated.

250 photographs, 160 pages, luxury issue. Price Euro 35,-. Available early 2003 from our shops in Eindhoven, Tilburg, Beek-Ubbergen and Weerdinge. The good reader will find in this book even at least 1 product designed by us.

Saturday December 28 2002 - 16.00

Attention! All of us will be back on thursday january 2, 2003. However, we do have to count and check inventories, so most probably it will be difficult to have demos on the first working-day of the New Year!

Sunday November 3 2002 - 16.55

For all owners of the AH! TjoUpsampler we have a small hardware upgrade. Instead of 1 Tjoeb Rib we will include 2 Tjoeb Ribs for a more stable installation. Also we will include a small cooling-device which might be needed in some cases where the ac-voltage is more off-standard than expected. Specially in USA we found this to be true. All current and future owners of the TjoUpsampler will receive this upgrade-kit for free. Instructions will be included. In the technical section of this website we will publish a Kevin Deal photo of (t)his cooling-device.

Friday October 25 2002 - 01.55

Finally -thanks to the help of Mr. Kevin Deal- we have added the instructions how to install the optional TjoUpsampler in the AH! Njoe Tjoeb 4000 cd-player. Click here to check this out in the Technical Section of our site.

The TjoUpsampler is very well received by the first owners and I dare to state that these new owners report back very enthousiastic about their "new class" cd-player. What's next, they ask.

Saturday October 5 2002 - 01.55

Attention! Saturday october 19, DÉ HIFIWINKEL EINDHOVEN will be closed the full day!!

Sunday, May 12 2002 - 01.30

Instructions and pictures have been added to the technical section for those who want to change the standard OPA604 opamps for the AH! TjoebTjoens (OPA627 or AD/LC825).

Friday, April 26 2002 - 01.30

This is maybe not the place to publish reviews, but as the following can be considered as a "mini-review" we still publish it here. Later on I can be reminded to publish it also in the actual review-section:

Marcel van Overbeek has listened to the 2 Opamp options (TjoebTjoens) we offer for the AH! Njoe Tjoeb 4000 cd-player and came up with following:

"Burr Brown OPA627. This Burr Brown opamp is probably made for those who are interested in very precise, sharply focused soundstages. It still is a very "musical" sounding Burr Brown, with great respect for tonal colour, and rich harmonic structures of instruments and voices. Bösendorfer sounds like Bösendorfer and Fender sounds like Fender. It has loads of air and distance between instruments, within the soundstage. The image also "opens" up, better and more "life like", compared to the original used budget OPA604. Detail and ambient information are the stronger points. What really stroke me, was depth and width within the "sound projection" which comes close to what I know from much more expensive CD players! The "to be there" feeling is enormous, and dull (often popular) recordings, are more "tasty" and way more enjoyable. But beware: it's that good that it simply proves how "bad" recordings can be... But after all, are we audiophiles not always looking for the naked truth?"

and he continues:

"
Analog Devices LC/AD825. This Analog Devices opamp is actually a SMD on a "mini pc-board" together with a couple of Silver Mica capacitors. It has a long "run in" period and is immediately impressing with very "warm" and lush sounds. In the beginning, I thought we simply made a mistake to consider this as a possible option: "There's no way, we can advice this little one!" I was thinking out loud ... Until I got the idea that perhaps the combination with my Philips E288CC SQ GP's was not the luckiest one. After installing the original Philips JAN 6922's it was immediately clear, that warm + warm was perhaps a little too hot ... The soundstage melted together and became sticky. Bass was simply undefined, until... Indeed. The overall presentation became way more clearer with the 6922's, and the sound reminded me of the early tjoeb days ... AH! Tjoeb ‘99 sounds ... Enough respect to detail and precision (better than OPA604) and a nice, soft, velvet top end. Bass and mid bass have more "compound" and mid/treble is "open" and clear. Voices are just to die for. I guess this one is best recommend to those listening to "small" loudspeakers, because it is -just little- bigger imposing. I really liked the "easy" and very pleasant dynamics. Nice ambient "sense" and great sound staging also came to mind."

General Conclusion: These options are highly recommended to those who want more of the good Tjoeb stuff.

Wednesday, April 24 2002 - 01.30

A full list of available AH! articles with the current prices for EC and non-EC members has been added to the website. Those of you who are hoping to see the pictures of the products once they click on the small cameras, have to be patient for a couple of weeks, I am afraid.

Sunday, April 21 2002 - 02.30

More information is added to the technical section of this site. Now information and pictures are published re the WAGO connectors we use in the AH! Njoe Tjoeb 4000.

Reactions on Tjoeb Tjoens and TjoUpsampler are very good. We have a
growing list of  reservations for the TjoUpsampler and our stock of Tjoeb Tjoens is almost gone.

Wednesday, April 17 2002 - 02.30

I realized today that there must be a number of "early" AH! Njoe Tjoeb 4000 owners who even don't know the current logos we use on the player and remote-control. For them we show these here and of course they can contact us for a free set of these.

The instructions how to replace the original OEM logos with the shown AH! logos, can be found in our technical section of this website. Click here.

Monday, April 15 2002 - 21.15

Just updated the technical pages with instructions how to install the AH! AC DIREKT KB 8 in the AH! Njoe Tjoeb 4000 cd-player. Click here to go to the technical pages.

Sunday, April 14 2002 - 23.15

Now and than we are experimenting with the products / prototypes in our stores, where we have lots of high-quality stuff to compare with. You cannot (and we don't want to) avoid that customers / visitors see and hear what we are doing. During last few weeks we have been playing on and off with our new AH! TjoUpsampler. If you visit www.audioasylum.com and search for " TjoUpsampler " you can see how fast good news travels! As said earlier this week, it is possible to reserve here for earliest delivery of the new AH! TjoUpsampler. This week I will make a few photographs of the proto TjoUpsamplers we have. 

Slowly by slowly we continue to create a special AH! section on this website. If you have any further suggestions, please
send us a short email.

Wednesday, April 10 2002 - 21.30

As announced last week, we do have a special choice of opamps for AH! Njoe Tjoeb 4000 owners, but also for other people who can use these single opamps for upgrading their equipment. As these TjoebTjoens are not needed anymore if you decide to buy an AH! TjoUpsampler (reserve here), we have a special trade-in programm for these parts:

The AH! TjoUpsampler's introduction price is EUR 325,-. You can trade in your original BB 604 set + Philips DAC for EUR 10,-. The Tjoeb Tjoens OPA627 set trades in for EUR 25,- and the Tjoeb Tjoens LC/AD825 set for EUR 15. This gives all the AH! Njoe Tjoeb 4000 owners the maximum possibility to "play" with their machine and sound at minimum cost.

Last weeks several customers have upgraded their ac and dc cables with AH! KB8 and AH! KB10 cables. All of them agreed this to be a major upgrade. One of our customers (owning Krell FPB650m amps and Wilson Audio Grand Slam loudspeakers claims his already good sounding Krell KRC-HR preamp sounds 10 times better with the new AH! KB8 connection between his powersupply and preamp. Watch out for further description of this upgrade, which certainly will become available as an AH!
Upgrade Kit.

Wednesday, April 3 2002 - 03.30

What you see on the left are two types of highest-quality OpAmps to fine-tune your AH! Njoe Tjoeb 4000. Same idea as what people do with different tubes. We have chosen for 2 sets. A set of 2 Burr Brown OPA627 OpAmps and a set of 2 LC-Audio/Analog Devices AD 825. Marcel van Overbeek has been listening to both of them and his conclusions will be soon available on this site. In fact they should already have been here, if I didn't mess up the story. By the way, the AH! name for these Opamps is: TjoebTjoens (pronounce: tube-tunes). The TjoebTjoens are available NOW from stock in LIMITED QUANTITIES. Enjoy.

Monday, April 1 2002 - 13.30

OK, it's done! You can click here for the AH! Njoe Tjoeb 4000 review in Hi-Fi World Magazine. ATTENTION! It's a long article with lots of photographs, so it may take some time to load. Have fun and off we go.

Monday, April 1 2002 - 01.30

Happy Eastern for all of you and hopefully tomorrow again some sunny weather (in Holland we celebrate 2 days of Eastern, Sunday and Monday). After that -and that is NOT an April 1 joke- we are going to play with the new interface-software for our Xenario© (yes, also known as PrPrPr) range of electronics we have currently under development.
