How good are these amps? I have 200w Class A mono blocks and have been eyeing these for sometime. What are your thought on them and hwo do they sound?

TIA

I was quite fascinated with what Trcnetmsncom had to say about his perception of a high end flaw in the MA-2s. Tom's likening this flaw to the high end rendering of the Martin Logan CLS 2Z made clear to me what he meant, because I auditioned those speakers a long time ago and I disliked them right from the beginning just because of that. I have the latest version of the Ma-2s, haven't rolled the 6SN7s so far and I just don't hear what Tom hears on my particular speakers, the big Sound Labs. Not that I doubt the sophistication of his hearing, nor his experience with live music. I share that with him, being a regular concert goer and intimately familiar with the sound of both violin and piano and just cannot find the flaw he mentions in my particular setup, which he obviously heard on several occasions on different rigs. This may well be a hearing impairment on my part, because I am advanced in age, however my wife, who plays the violin also cannot find anything wrong with the Sound Lab's/ MA-2 rendering of her instrument. We listened again extensively to Hilary Hahn's exceptional rendering of Bach's Sonatas and Partitas and could not find this particular shortcoming.
We then tried piano on LP: Martha Argerich's rendering of Liszt's b-minor sonata, an early DG 2530193, again the highs were clear, crisp, without a trace of harshness or brightness. So this is puzzling. The big Sound Labs are not an easy load, but obviously pair very well with Ralph's bigger amps. Possibly we have just struck it lucky with this combination and would have been equally unhappy, trying the MA-2s with the Avalons. No lack of "denseness" either, with our stators to our taste and ears.

Thank you Tom. I found your contributions both important and thought as well as "hear" provoking. Obviously we strive for the same thing, the best balance of all "sonic virtues" as you put it so well, with "no area severely lacking". Obviously your benchmark is your experience of the live event as it is mine. We may have different tastes and rigs, but it feels good not be alone in this.
