Thank you, Plato, as well, for your thoughtful advice.
( that took me back a couple of thousand years)
I agree that final determination is within one's own system. But, I'm somewhat familiar with the system it demo'd in and it was with two different speakers, two different CDPs, and I swear it was with the owner's all tube system until I saw the Genesis amp sitting there, grinning at me (I think it winked as well).
As soon as I pay down some debt its time to audition some class D amps.
Its nice to be in the hunt, again.
All the best,
Nonoise
