Most amps sound different. Though it is subtle in similar dedigned tube amps with same tubes. I own an arc with 6550's and the P12's which have Kt-90s they both sound great. I would say that the CJ is a little more romantic, its hard to explain. While both amps have great soundstage and defination the CJ is a little more softer , mellower sounding. You can also check with Kevin @ www.upscaleaudio.com in regard to which tubes will suit your music style. Both amps are among the best available. You will probably love either one. BTW make some room they are both pretty big !
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.
