The KT120 compared to the 6550C Tubes


I have a ARC Ref 110. I'm thinking about up-grading to the KT120 tubes.
Would the KT120 tubes enhance my amp? thanks Rese59

Thanks Gpgr4blu, This is my first tube system, which also includes REF 3, preamp and a PH-7 from ARC. just looking to tweak what I have right now and move up to the 5SE, and the REF 150 later.
