@ctwith3 Those amplifiers were owned across the years, even now. I just rebuilt a Sumo Polaris and a GAS Grandson, both with very high quality parts and they both responded very well. I'm surprised how good these old amps sound. But I've had 3 different Sumo's, a couple of Gas, an old Coda, Classe, Parasound, Kenwood Mono's, Kenwood stereo, an Edge, Yaqin, YBA, Heathkit (still have AA1600), 2 - PS Audio (200c & Delta), a Hafler DH-500, Kinergetics, a Marcof, an old Arcam.... right now that's what I remember.
Actually, these were mostly all decent sounding products. The Kenwood mono's were L07m's. I enjoyed those, but afterward, I bought a Basic M1, I did not like that, also had a Parasound, don't remember the model, employee purchased it in 1980, didn't love it. Again, these are all pre 2000 models.
I'd love to hear the Virtuouso. I had an Aria integrated a couple of years ago, it was a huge value and very nice sounding piece. I just built several Class D amps and am rotating 2 of those in and out of the system with the Sumo and Grandson. I am currently using a SST Ambrosia preamp that I really like. Not sure this answers your questions, but there you go.
