You would benefit from some good advice from ANDY @vintagetubeservices.com He would most likely say a set of REAL kt88's are the way to go. Of course you might not want to spend $300-$400 a tube for that amp it might be overkill. The cayin is autobias so you should be able to try out those kt120's with out any issuies. If you really want to find out what would happen ...call USATUBEAUDIO.com they can tell you all about the cayin amps. they are a big dealer for them in the USA.
