Best 845 amp?

Tmhaudio, re the 845C question, I don't know. Sophia claims theirs is new production. SuperTNT, having stopped selling the original "C" under their own name and discouraging people from buying it, may well be selling from old stock. I had a pair of the "original" C version and did not like it as well as the "B" in my amps. But this new one from Sophia is much better. To me it's certainly worth the difference in price, which shrinks a lot if you factor in the cost of getting it shipped from China (from SuperTNT).

Dopogue - thanks for the comments.

Two questions re: the "new" Sophia 845 metal:
1. Does it have any special requirements re: plate voltage? My understanding the original 845C had a problem in this area.

2. Are the overall power & dynamics reduced as reported in the original 845C?

Thanks again for the comments!

I'm not technically knowledgable enough to be able to help, sorry. I do know that my amp designer/builder had to alter the bias substantially (up or down? don't know) to accommodate the 845Cs after my using 845Bs. This despite the fact that Sophia said no bias change would be necessary.

Regarding dynamics, my sense is that these particular 845Cs are quite a bit more dynamic than the Bs. Whether they're more dynamic than the original Cs, I'm not sure but I think so. Dave
