The CJ premier twelves have a naturally warmer, more easy going sound than ARC amps and more than most amps actually. My choice would depend on other gear in the system.
Do all 6550 based tube amps sound the same?
I am looking to add a tube amp to my system. Both of the amps I am interested in, Conrad Johnson Premier 12 and Audio Research VT100 MK 11 or 111 use the 6550 output tube. In your experience do they all (6550 tubes) share a similar sonic signature? Thanks for your help.
