I used a Plinius P-8 amp for a while driving Shahinian Hawks in a well-damped 2000 cubic foot room. The P-8 is the amp section of the 8200 and is, according to the distributor, virtually identicalto what they are now using tin the 9200. I listen mostly to large scale Euro-classical orchestral stuff. The P-8, and the SA-100MkIII I now have, both seem to expose wll the brightness present on your source material. Mellow cd's and lp's can sound beautifully full and powerful. But, anything less than smooth on top will sound almost (to me) unbearably bright, especially on violins and trumpets. I noticed this the very first time I hooked up the P-8 and still notice it, to my chagrin, with the more expensive and sophisticated SA100. If you have speakers that are trelatively flat on top, this could be a problem. It could be that the Plinius is a very accurate reproducer and you get out what you put in. It could also be that the Plinius is best matched with speakers that are a bit rolled off in the treble.
Otherwise, these struck me as very fine amps.
