Audio Horizons TP 2.0 Preamplifier

I forgot to mention that amps and speakers also have to be matched up properly. Another tough decision for Joseph because of the wide variety of speakers in our systems. Yes, I can understand with Grannyring's recommendation of a 200W amp, but what about the die-hard SET camp using these amps on their ultra hi-efficiency horn systems. I have read a few posts where some audiophiles have gone with the new Zu speakers which are very efficient and are selling their mega-power amps for lower wattage SET, etc. Just another example making it difficult for Joseph to make a decision.

I switched from solid state amplification to SET combo with a 95db efficient speaker and never looked back. Its very revealing especially with Joseph's preamp. It also makes it possible to match inexpensive digital as the source while preserving musicality.

I also made the switch to SET 2 years ago and came back to my current, more conventional, set up with the AH dac, pre and Belles Ref 350 amp. They drive a pair of Dali Grand full range speakers (90db effecient).

I liked my SET system which consisted of George Wright 2a3 amps, Cain & Cain IM Ben speakers, matching subs, George Wright preamp and a Audio Aero tubed CD player. In the end I missed the scale and impact of a "full range" system. Sure, this system could play very loud and had good dynamics, but in the end it was not as flexible it terms of playing all kinds of music well. Loved the intimacy of SET, but found I could have it with my current system and enjoy improved dymanics and scale on other music.

I only say AH should consider an SS amp as I think (?) the SET lover is a far smaller group and potential market. I have also found one can get most of that SET sound with a carefully matched and thought out dynamic system. I know some SET systems can be dynamic and have a good degree of impact and scale, but I think we can agree they are still a step behind the best "conventional" systems in this regard.

Agree on all points. I believe what you are describing is personal taste and style. My system can be very dynamic (tube change, maxed out front end, etc) given the source, and since my speakers extend to 22 hz, its sufficiently scaled to my personal taste. My room is a significant component and I am glad its not so conventional.

I have been able to tweek Joseph's preamp to maximize midbass and bass dynamics with little compromise. The amp I am using is custom with 6 seperate power supplies as the main generator, so there is no craping out on dynamic peaks. So the heart is Josephs AH pre and the amp/speaker are the brains. Perhaps the only weakness is the digital front end I am temporarily using. But perhaps not.

A friend came to visit and declared the system outrageously good and was shocked at the bass output of the system.

Overall, perhaps the decision is going to be more who is the bigger audience and you are probably correct on that score. Either way, I predict he will be successful.

La45, I would love to know more about your amp. Who made it etc? It sounds very interesting to me. You're right about personal tastes and style. Funny thing is they change and someday I may be back to a SET amp. Don't know, but for now I am pleased with my current set up - just as you are.
