Be also noted that old KSA series will most-likely need complete overhaul before you can actually use'm. They run extreamly hot and may develop dried out DC caps.
Recommend Class a Amp
This past weekend I purchased some Infinity QLS-1 Speakers and the gentlemen I bought them from was powering them with a Krell KSA-250. I was impressed, how the Krell drove those speakers. Most of my amps are tube and I would like to get me a keeper used well thought of class A solid state amp. I would like to stay in the Under thew 3K price range. Look forward to your recommendations.

Good call by Czarivey and Bombaywalla. I dug out the original Stereophile issue to see if there was a manufacturer's comment in response to what JA had to say, and there was not. To the OP: If I were you I would forget about pure class A operation and jump on this refurbished Threshold S/500 Series II, being offered by a dealer at $2495. I note, though, that in addition to being listed at the dealer's site he is offering it with a "buy it now" option at a well known auction site, so it could be spoken for at any time. I have no affiliation with or knowledge of the seller. Regards, -- Al |
This could be interesting... http://app.audiogon.com/listings/solid-state-pbn-sierra-audio-whitney-power-amp-2015-03-13-amplifiers-32713-debary-fl--2 Looks like it can be run Class A/B or A, and it comes in at half your price target. 120 Wpc but doubles to 240 Wpc into 4 Ohms I'm guessing in A/B and 100 Wpc in Class A that may well double into 4 Ohms. Here's the kicker, you can buy two and still be within your budget and probably be at 200 Wpc pure Class A. I've heard Peter's amps and they are quite special. Very well made and designed and consistently get stellar reviews. I'd be sorely tempted if I were you given your budget and requirements. No ties to seller BTW. |
Yeah, in a quick search I wasn't able to find specs other than a reference to the Whitney in this Ultra Audio review, which is where I got my 100Wpc Class A spec from. http://www.ultraaudio.com/equipment/pbn_olympia_l_mini_olympia.htm I know that's kinda weak. BTW, what does "2...5Wpc each in Class A" mean? Not sure I follow. I know Peter does seem to favor using relatively large transformers in his amps, which made me think 100Wpc Class A could be possible. He is also very high on the power and performance of his amps in mono, so I was kind of (maybe incorrectly) extrapolating that those past design elements may have also made it to the Whitney. But again, not having seen the specs I could be completely off base here. |
