6550 to KT88


I switched out my EH6550's to JJ KT88's yesterday in my Rogue M120's, quite a difference from the get go...much better bass, sound stage is wide/deeper and overall I like the way they reproduce the music better... so now I'm wondering if the KT90's will be any better? Anyone go from the 88's to the 90's and stay with the 90's? Thanks for your comments.

Be very very careful with the JJ KT88s. Their reliability was a disaster for me with them not lasting more than 6 or so months. Upon destruction, they launched a power resistor in the amp (ARC VT130) each time. I went back to 6550s, lost a little of the midrange warmth but gained a more neutral tonal balance and reliability to boot.
