OP here, chiming in. I don't think nonoise hijacked my thread at all, in fact he has presented a very tempting speaker, based on the reviews he referenced. I was struck by how similar the Ryan and Revival Audio logos are. Not intentional, I'm sure, just a point of curiosity. I hope a dealer local to me (northern California) will carry the Revival Audio speakers--I'd love to hear them.
Meanwhile, thanks also to Celtic 66 for the suggestion. I rather suspect that my Furman power conditioner is kind of weak link in the chain. I used to own a PS Audio Power Plant Premier, but it failed and couldn't be repaired by PS Audio (couldn't get the parts any more I was informed) so had to sell it off at a fire-sale price. I did like what it did for my system though, when it was functional.
