I can't speak to the EH KT-88s. But my old amp originally used SED 6550 "Winged C" tubes. IMO, dropping in the KT-120s made a significant positive difference.
Right now there are a couple of threads running about the recently issued KT-150 tube. New Sensor makes both the KT-120 and 150 tubes.
Just a suggestion, but why not ask Cary if your amp can handle the KT-150s? It's a little pricier than the KT-120s, but others have written some really positive comments about the KT-150s.
Gotta tell ya Jake ... I must be an audiophile now. I never thought I'd be a tube roller, but I'm waiting for ARC to sprinkle pixie dust on the KT-150s to drop into my Ref 150 amp. And why??? The amp sounds great as is?????? I'm surprised at myself. :(
