I am commenting on your speakers.
I just picked up the Total Victories after living with the smaller Victories. Wow!!!. Beg borrow and steal if you have to, the Totals are that good.
I am going to try a few different tube amps, 845's, PX25's, and my present Coincident 300b amp. I think the load of the Coincident line make amp choices easier. I like female voices, so the PX25 tube might be more to my likeing. If you listen loudly, than the 845's are a great tube.
I can tell you upon first listen, the Coincident amps sound better with the KR300b BXLS's than with the Sophia 300b. Yes I have both in house. I can not comment on the new KR 845's, but I saw their new run. These things are built like tanks. No listening observations.
Good luck.
