Had the S300, but was unsatisfied because its power output was woefully inadequate; consulted James Herod at PS, and he talked me into trading it in on a pair of M300s. So I did...better power, but still a disappointment overall, though I will say that the tonality of their amps is above average; probably their "gain cell’ at work. Would like to hear Bel Canto’s similar amps, which have garnered high praise ~ as I’ve said in other posts, I miss my custom-made Odyssey Stratos; not sure digital [or type D] amplifiers can ever generate enough "grunt" [amps] to achieve the slam of A/B amplification.
Love Paul’s approach, love that it’s US built, love the cost to value ratio, love the customer service...although it cools somewhat when you’re still not that impressed w/their solution, which is usually an upgrade w/in their line, as in my case.
But, and it’s a big BUT, it really does depend on your system and the synergy between parts, and w/the room ~ hardly an original observation, but I do want to concede that their gear may sound fantastic in some systems/rooms. And, to an even greater degree, the most important criterion may be the sound you’re looking for...or should I say, listening for? But like a few others who’ve posted above, I think I am done w/this company ~ my next amps will probably be the big heavy SS monsters that I was trying to be done with...oh well, we learn as we go, right?Hmmm, I hope that this doesn’t sound too negative, I do think PSA is a good outfit ~ their sonic approach is just not for me
