Update: I don’t see a lot of documentation, but I’m getting the impression that the $6-10K T+A integrateds are all Class D. I’m willing to concede that there are some really superb-sounding Class D amps amps out there, but without the ability to audition before buying, I’m staying away from D topologies across the board. Dumping my current well-reviewed Class D amps is one of the main motivations for my current upgrade.
Re: Chord, I’m amazed at how much misinformation there is on Audiogon about this company. Some of the most adamant posters even confuse the Chord cable mfr with the Chord amp/DAC company. Sigh.
Chord makes Class AB gear that lowers weight by utilizing a switching power supply. But, jeez, that's not a Class D topology. And while SPS’s are associated with switching noise, that’s not an automatic dealbreaker. A well-designed product -- like the Chord amps, apparently -- can prevent that noise from polluting the audio signal. That's hardly news.
The pudding for me is that Chord reviews in the more credible audiophile press are consistently glowing, and seem to position the overall SQ of the Ultima line (starting at $11K) maybe one level above similarly priced offerings from the likes of Benchmark & Byrston. (The Ultima Reference line is out of my price range, so I haven’t investigated it.) And those who own Ultimas give high praise to their performance. Some claim that the Chords sound best with systems like Martin Logan electrostats and Wilson Sashas, and not so much with "lesser" speakers. But that's a can of worms I can't address without first-hand experience.
Hey, I don’t have a horse in this race, and have no commitment at this point to a Chord purchase. But after a deep dive into the company, I've come to the conclusion that its amplification products don’t deserve to be dismissed as "overly bright", much less Class D-compromised or, even less rationally, being criticized as being (in the worst possible sense of the word) "pretty." Come on.
The Chord Ultima Integrated may be a bit beyond my budget at $11,250 for an analog-only integrated, but I’d still add it to my A list, along with Benchmark, Byrston, Ayre, & Hegel integrateds. It seems to be a well-conceived, well-designed, and well-built product. Not sure how well it would mate with Harbeths, but I get the impression that a good fit is not unlikely.
Any Chord amp owners (not DAC owners) out there who'd like to contribute some first-hand feedback?
