Gjames, yes the unit has gold pinned Siemens tubes.

Tvad. I am currently auditioning AH against a ss pre. I dont know if this will help you but my system was very detailed and on the best 10% of CD recordings couldn't please me more in terms of clairty. But on less ideal recordings and higher volumes it could sound a touch strident or etched. With the AH preamp the best 10% is much more gorgeous and the next 70% have become beautiful to listen to, all without losing detail and clarity. Yet I would not describe AH as warm in any "cover it up way" rather it sounds more like real instruments, with acoustic instruments having their natural warmth and electronic instruments very smooth on new age stuff and acidy on acid rock. So I am being drawn to listen to the large amount of music in my collection that isn't the top 10% and finding much of it captivatingly beautiful, powerful or sparkley or soothing whatever it was intended to be. That is a real treat. As this is occuring in a deeper soundfield with more air and surer location of voices or instruments. Fellow owners - did I capture some of the appeal of the AH? |
Gammajo. I fill is very accurate with his description of our AH. The more I listen whether to relax, or to listen critically. I realise how much more natural all instruments are coming across including placement of the performers. I listen to Vinyl most of the time, but with the recent purchase of my AH, I have been playing CD's quite often and find these qualities to shine through both. I also come from a SS Preamp, one obvious difference was the liveliness of the music, everything seems to be played in front of you as opposed to listening to the acoustics of the studio which I have found in some systems nice, but not for me. |
Gammajo, You described it very well. My original brief review was posted on the Audio Horizons website, similar to yours. I think we're all on the same page here as far as sonic descriptives are concerned, and that says a LOT. The TP 2.0 combines the classic tube sound without the added artifacts yet remains neutral with a natural warmth. It also slams out the yang-yang with micro and macro dynamics and a dead quiet background. My next move is sending Joseph my CEC transport "which he is very familiar with" to work some magic into. |
It's been mentioned before in various threads that Joseph can work wonders with older, as well as newer, tuners. If you have an older,analog tuner, for @ $300.00 Joseph can turn it into one of your favorite used sources. I find myself listening to my local NPR college station quite often into the late hours. |
That's exactly what happens when your equipment is quiet. You're able to talk (without shouting) at normal conversation levels while music plays. Running dedicated 10-2 lines helped further, the only thing I did was drop the ground inside my preamp at the IEC to eliminate a hum and I made a cutom black acrylic lid for mine. |
Joe, Both Victor and Joseph are very helpful in recommending certain vintage tuners. Joseph might have a few in stock that he has for sale. Check with Victor when you're ready. Also, the louder and softer sound effects that you hear with familiar music are the macro amd micro dynamics discussed which the preamp excels at. |
How many of you have the remote version of the AH 2.0 preamp? I am just curious as this option is brand new. I am just loving it to death and can't wait to listen to more of my CD's. I wish Mr. Chow would make a nice SS or tube amp to mate with this preamp. Based on his pre and dac , I'm sure it would be fantastic. I would also like to know if any of you use tube dampers on this preamp. Thanks, Bill |
For me, a remote is a requirement since moving to a computer-driven delivery setup. The ability to pick and choose tracks, which almost always vary in recording level justify the remote. Much different than popping in one CD and listening end-to-end, in which the levels mostly remain constant. Just my take... |
Grannyring, If by tube dampers you mean flexible rings that can be rolled down over the tubes to quiet vibrations due to heat and signal then, yes, I do use them with both the preamplifier and the DAC. I was surprised to hear that the rings do improve the music slightly. I use the Siemens ECC tubes provided by Joseph as an upgrade. I bought the rings that I am using on Audiogon. There may be more sophisticated materials available. I have not tried others. Rand |
Now that my TP 2.0nB is a permanent piece, I am wondering anybody have first hand comparison too Joseph's Dimension interconnect and Cardas Golden Reference. I have the Cardas and like it's signature sound, I need one more set of cables for my CD side, and I'm curious about Joseph's. I'm so pleased with his Preamp I'd be willing to try his cables! |
Grannyring, check out Herbie's Audio Lab for tube damping rings, best stuff out there. I also use his special footers under my components, including the preamp. Herblin is a friendly, honest guy, his products *really work* and the prices are down to earth (like Joseph Chow) Something barely heard of nowdays in audio land. |
My impression (no science here) is that the myrtle wood is particularly good at draining vibration off and away from the audio gear. My audio shelves are suspended from the wall. I can jump next to them and not disturb a turntable playing. For this reason, I perceive the value of the myrtle wood blocks as "vibration drained away" rather than as "vibration prevented from reaching." It might work both ways - I can't tell. Perhaps I should add that my shelves are wood, too - plywood with many coats of paint applied. |
Rgd, Victor can recommend some good dealers for you. Joseph and Victor both prefer the sound of Siemens CCa in this preamp, however, one owner that gave a testimonial in Joseph's web site liked some NOS Amperex. The preamp comes stock with EH( Electro Harmonix) tubes, which sound very good in Joseph's excellent circuit. Joseph's upgrade is, I believe, a 70's Siemens E88cc, which will give you a little better sonic picture. The ultimate tube for this preamp is an early 60's Siemens CCa, but they are getting rarer and very expensive. One nice thing to consider is that there are only four tubes in the preamp, and basically only two of them which are fairly critical in the audio signal path( tube locations 1 and 3 ). I was able to find a good pair of Siemens Cca for these locations and am using some late 60's,early 70's Siemens E88cc in locations 2 and 4. My recommendation is that when you get your new preamp, allow it to warm up for a few days to break in the preamp and get an idea of how it sounds in your system. You might just like it so much with the stock tubes that upgrading might become an alternative that you can wait on for a while. I lived with my stock preamp very happily for a few months before I got the urge to try some upgraded tubes in location 1 and 3. I hope you enjoy the preamp as well as I do. Happy Listening. |
An excellent source for NOS tubes is Brent Jesse, [email protected] helpful and very fast turn around time.And hey,welcome to the most exclusive pre amp club in town. |
Well, I have over 300 hours on the Audio Horizons preamp, so it is time for a mini review. I hope it helps folks considering the preamp. I welcome comments and questions. My musical taste favors classical, pop, and rock. I play piano, sing and listen to live music often. The most important aspect of sound in descending order for me would be: natural and non-fatiguing, excellent portrayal of timber, detail, ability to convey instrument and hall decay, accuracy, fast dynamics, bass fullness and slam, and stage width. Less important for me is stage depth and height. The worst thing a system could do is to be strident, harsh, cold, thin, or muddy. My version of the preamp has the capacitor upgrade and the gold Siemens tubes with only the output transformers upgraded, so I guess you would call it a TP 2.0n1/2B. The unit is attractive to me and wife with nice wood knobs, blue LED, black faceplate,and a solid look and feel. Inside is very clean and carefully laid out. My electrical engineer brother was impressed with the layout. For purposes of this review I mainly used Franz Liszt Transcendental Etudes, Kissen on RCA CD because this piano work is challenging in dynamics, frequency range, transient attack and decay, and compression due to complexity of signal. I also have a grand piano in the same room as a reference, though I can not play to Kissen’s level! My equipment is perhaps not as resolving as some of the folks owning this amp but this review may be useful for those who have a decent if not ultimate system. The main thing I notice with this preamp in the system is increased changability much like live music, rather than a “here we are listening to the stereo again” feeling. For example the contrast between low and high volume that is so dramatic that the volume changes surprise me on well-known pieces. The preamp easily conveys music by turns thrilling, poignant, tender, energetic – whatever is called for with a greater difference in these different “tones” than I ever heard on a system, and moves instantly and effortlessly between them. Also there is more noticeable difference between different pianos, violins, and artist styles etc, not only in timber but also in overall gestalt, so that all instruments and artists have their own personality. Added to the delight of contrast are many other wonderful attributes. The unit possesses tight, controlled, dynamic, and accurate bass, a wonderfully open, natural and slightly warm midrange, and extended, airy, easy highs. There appears to be zero compression even at high volume with complex music. The main feeling to the sound is sparkling, full-bodied, nimble, beautiful, and non-fatiguing. There is a sweetness and naturalness that is heart opening, much like live music. Sound emerges from a very black background, ultraclear and resolving, but with no trace of stridency, harshness, or grunge. It maintains a good bit of the excitement and delight even at low volumes. Soundstage width, depth and localization are all excellent. As mentioned in other posts, now almost all of my CD collection is listenable at higher volumes without fatigue. Vocals, rock, and New Age are all conveyed well. Male vocals are particularly right. Dense choral works and brass ensembles both are much more interesting and enjoyable to listen to. Hall ambience is conveyed very naturally. I can easily see why some have traded in well-respected and much more expensive preamps in for this baby. They were not just after something new. I would very willing to say that in my system this pramp lacks "X" but I truly at this time can not find anything. It has helped me take a giant step toward fulfilment. Next to speakers it is probably the biggest improvement I have experienced in my system. Finally I have truly pestered Joseph the designer and Victor his representative obsessively before and after the sale. I would guess there had been nearly 100 emails and repeated phone calls. Victor has taken much time teaching me about tube selection and buying. They have always remained responsive, clear and helpful. I rapidly felt that they were friends who were truly interested in my satisfaction and shared my perfectionistic passion for music, not equipment. Associated equipment: Aragon 8008BB 200Watt per channel dual mono SS amp, NorthStar 192 DAC and CD Transport, Guerrilla Silver IC and woofer cable, copper to the mid/tweeter biwired, Audio Horizons XRL preamp to amp. |
Gammajo, wonderful review. Your words are well chosen and I am enjoying the very same experience with this preamp. Nice job. I could not agree more with your comment that I love this preamp not because it is different, but because it does not sound like a stereo. It does sound more like a live performance. Best preamp I have ever auditioned or owned in my systems over the years. No reason not to try one as AH offers a trial period that is no risk. If a preamp exsists that sounds better at even triple the cost, I have not heard it. Baranyi, I have owned the Cortese and Syrah preamps from Supratek and both are very good. I did not use the phono sections however. As a line stage the AH preamp is superior to my ears to both these units. It is more dynamic,much more quiet, more powerful bass, more neutral, equal in rendering of natural tone. The AH far exceeds the Supratek units in terms of clarity, intimacy and imaging. It sounds more live and engaging! If you don't need phono, the AH unit is the easy choice. Joseph is also here in the USA with a 3 year warranty. Bill |
Thanks for the positive feedback, Bill and Mark. my plesasure to help spread the word. Yes, if Joseph builds it, we will come! Just ordered cca's for postions #1&3 and early 60's gray plate Siemens for #2&4. Plus Herbie tube dampers. Will be interesting to see what that does. Also I have been getting great results with a strange tweak. Instead of the myrlewood blocks under the preamp, I am using a tweak that cost me about 20 cents. From Lowes, I obtained a six foot length of polystyrine pipe insulation (a spongy black tube). I cut 1 1/2 inch rings off of this and placed four of them under the preamp. I also have them under my DAC and Transport. My oak shelves are not isolated well from the floor. This wells well for me in this situation. |
I watched several pair go on Amazon and at dealers for way more than I wanted to pay, so I searched audiogon threads for members that seemed to like the cca's, and who were knowledgeable and helpful in threads. I then wrote them asking if they might have a pair at a reasonable price. I recieved some very kind responses with the fellow I got them from selling me his last pair,as he is using Amperex more right now. I got my gray plate 88cc's from him as well at excellent price by being willing to go used rather than NOS. |
LA45 I found the Siemans they sent with the preamp to be wonderful, and in fact the stock EH tubes are quite good too. The unit is just so awesome that I wanted to try the NOS tubes suggested just to see if even more performance is possible. I will be trying my NOS and will report the comparision in about a week. Sherod and others may already be able to answer your question in more detail but the preamp definitely sounds great without the NOS treasure hunt. If I played it even with the stock EH it was a dramatic improvement over any other preamp I had heard. |
I agree with Gammajo. The stock tubes in the preamp are very good and provide wonderful musicality. The upgraded tubes do make an improvement, but depending on the resolution of the rest of your system, the difference isn't huge. For me, the early 60's Siemens grey plate CCa tubes just fine-tuned the overall sound to give me the ultimate tone and timber of instruments. The preamp is so transparent that cable and power cord additions can clearly be heard. I recommend that you start out with the stock tubes, or Joseph's upgraded Siemens, then live with and enjoy the sound for a while. Experiment with tweaking the cables, power cords, and room acoustics until you've extracted the best sound possible. Then find a hopefully good deal on the early Siemens CCa( preferably in tube locations 1 and 3) and you'll hear the magic of Joseph's preamp more clearly. Enjoy the journey and happy listening. |
By the way, the best analog interconnects that I've ever found and unfortunately they aren't well known, are the silly sounding Chinchilla interconnects from Von Gaylord Audio. They are expensive and a used pair are rare( I'm looking for one more pair for my Cd player if anyone has some for sale)The best power cord so far that I've found to mate with my preamp is the Electraglide Epiphany X. Here is a review of the Chinchilla interconnects: http://iar-80.com/page90.html |
I just thought that while I was on a roll tonight, I'd put in an addendum that as good as Joseph's preamp is, his vintage tuner upgrades are equally impressive. If by sheer luck that any Audiogon members happen to live in an area where they have a good NPR( National Public radio) station which is minimally compressed, have a decent antenna, and if you like some really great live jazz and classical broadcasts, and you just happen to have an old decent tuner either sitting idly in your system or gathering dust in your closet, send it to Joseph for his $350.00 refurbishing and be prepared to have an enlightening experience and a new regular source to listen to. Until I find another Chinchilla for my cd player, I've been staying up many late night hours enjoying my Joseph-tweaked 1977 Citation Eighteen tuner. |
