I would use the coincident as a amp alone ...bypassing the pre stage using my wonderful (first sound audio preamp from Emanuel Go ) but u think the Canary amps would be better off .... That's nice to here as so many a-gon talk trash about my canary amps ...I just really wanted to try the 845 tube ...I think I might just stay with them I can't see a 6k dual mono being as 11,900 k mono blocks in separation an image placement !! Thanks I was almost ready to do it but was very reluctant !! Thanks again !
