Digital Amps - Your opinions and why so few?

Thanks for comments offered so far. I want to believe that a pair Carverpro zr1600 can sound better than a pair of Pass X600's, it's just difficult to digest, given their retail price difference. I'm not a hifi 'snob' and have no 'issues' with Carver amps, or Bob Carver, as some people on AG seem to have. I just don't want to go through another round of buying and selling.
Vince, I know you've been flying the flag for the H2O's, I'm sure the amp is every bit as good as you suggest. I'm worried however about buying into something that doesn't have a real track record. Also, the fit/finish looked a bit unprofessional on the photo's that Henry sent, so resale value and reliability is also a concern, that and his price has gone up $1000 on the monos, not to mention the 3 week leadtime.

I wish someone could do a head-to-head between Tact and Pass, or Carver and Pass etc.
Audioengr....you mentioned bass performance when comparing the ZR and JC1's. Were the ZR's stock or modified?...what other insights can you offer about the two amps, beyond the bass performance? I read the shootout you listed and it seemed inconclusive. Clearly one of the people was a tube fan, and didn't respond well to the presentation of the ZR, the other people seemed undecided on the relative merits of each of the two modified Carvers.

Anyone else with digital experience that could offer a side by side comparison with high end analogSS?

Thanks

I'll second what Ramy said about the Acoustic Reality eAR amplifier. I hate to use adjectives like "analog" or "un-digital" to describe its sound because I don't believe in these terms. But I will say that it sounds "right" and "natural", and that's about the highest compliment I can give to a piece of audio gear.

With respect to the key topic of this thread, I think that that digital amps have already grown to dominate the low-end. Just look at the plethora of receivers from the likes of Sony, Panasonic, JVC and others, and you'll be hard pressed to find one that doesn't use a switching amplifer circuit. This is not meant as knock against the technology, but it's merely a reflection of its potential for lower cost which plays into the busines model for affordable consumer gear.

The high-end market is a different ballgame altogether where demand is low, margins are high, and the consumers (though few in number) can be demanding, superstitious, and fickle. For this reason, I think there will always be a market for diversity in the high-end so that digital, linear SS amps, and tubes will continue to co-exist for the foreseeable future. As to the question of why there are so few currently, that's certianly not true in the low-end consumer market. Digital amps are only relatively scarce in the high-end, for now, because of its newness, yet I don't expect it to dominate this end of the market like it has in the low-end for the simple matter of what I noted earlier about how demanding and superstitious this market can be. To wit, the term "digital" still carries a stigma to this day that's hard to shake, whether it's wholly deserved or not.

I have an Acoustic Reality digital amp. These amps have a conventional toriod for the power supply & ICE modules for the digital section. This amp sounds very good to me, so did the Spectron I borrowed from a friend.
I do have a Debussy CD that has some very low level room noises in the performance. I now use this as my reference resolution test CD.
The AR amp clearly re-produces the louder of the 2 backround noise incidents. Any of my Pass Aleph amps makes both easily heard.

I am a dealer for the new Flying Mole digital amps. Shown at Cedia a few weeks ago, their is a review in the current edition of Widescreen Review by Gary Altunian. For addt'l comments see www.stereotimes.com and search for the review of the Von Schweikert dB99 high efficiency speakers. The writer comments on the DAD-M100 pro here as well. Affordably priced, compact in design, efficient and generating little heat, these 100watt giant killers have attracted lots of attention lately for 2ch and HT application.

Rooze, the pics you saw must have been of his very first hand made prototype. My amps have perfect fit and finish. All the ones I've seen pictures of coming off the line are the same. I hear you on the sales lag time. There is a waiting list. As for resale, I know several people that would pay full price for my used monos.

Oxia knows I owned an Acoustic Reality, and the Pass X600. There is no doubt for anyone hearing all three, the H2O is the finest al-rounder. There are several items separating the H2O from the Acoustic Reality. For one, the H2O has an independent power supply, not borrowed from winds on the output transformer. The H2O transformer is a kilowatt.

A thousand dollar increase was necessary. The H2Oo amps are substantial amps that do not cut corners anywhere. The $4k price is way under some competitors, and equal to others. Henry offers a free trial for prospective buyers.
