Anytime Henry!!
I thought your amp was the overall winner. But maybe it was just a case of greener pastures, we both liked each other's better. To me the RM9 was more dynamic, more controlled, quieter and bass control extended a half octave lower. More power is always a nice thing. The output transformers are bigger on the RM9 and the tubes make more power too.
I saw some used JC1s on the goner this week, $6k! That was the list price not too long ago! Now it's 9k!!! For Parasound! I think they are getting proud, as they should be. Last year there was a half dozen pairs on there at once for $3k.
Two days ago I got the crazy idea to try my Altmann BYOB amp on the Ushers. It was packed and ready to ship from an ad on AudioXchange. But nobody wanted my poor little amp
so I ripped it open and powered it up, originally think I would try it as headphone amp. It is still only about 7 watts on the 6 ohm Ushers, but man is it beautiful. Dead silent background, and clearer than any amp I have ever heard. And I can play it in the summertime when thunderstorms come every evening in prime listening time. So I have some ideers on how to scale up the battery powered chips to handle the speakers at full volume. I'm also planning to build the Pass F5 and B1.
