A few comments.
@psnyder149 found the Classé CA 2300 fan inaudible. I agree that it's a fabulous-sounding amp; in fact, I was about to buy one. But in my audio room, when I was listening to string quartets, the fan became audible during quiet passages. I'd urge caution in this respect for prospective buyers. Most listeners don't mind the fan, but some of us do.
@georgehifi points out that amps that use reduced feedback might have "high" THD, around 0.1%. I agree with George that that amount of THD can be inconsequential. It's difficult to hear, and I would not rule out an otherwise well-regarded amp for that reason. THD, especially 2nd and 3rd harmonics, is far less objectionable than IMD.
On Classé repairs of older equipment, I urge caution again, and I'd ask Classé how repairs might be handled for a specific model. The last information I saw from Classé (during resurrection from the B&W closing) was that older products would be handled by B&W but that parts availability might be problematic. So, wise to check before buying.
And @timothywrite, I sympathize with the difficulty of getting anything done these days. Looking at Audio Advisor, I see Bryston again has raised prices, with the 4B3 MSRP going from US $5995 to $6795 (though currently discounted to $6115). That would be one way to get a home audition, but boy, Bryston sure has become pricey!
