I use a Cary SLI-80 in a secondary system with Merlin TSM_MM and I found this tube compliment to work very well and is very musical.
2 ea - Amperex 7308 Input Buffer Preamp
2 ea - Sylvania 1952 6SN7GT "Bad Boys" Pre Driver/Phase Inverter or Russian metal base 1578
4 ea - Re-Issue Gold Lion KT88 Output Tubes
2 ea - GE 5U4 Rectifiers
I run the amp in triode mode and it sound is very balanced with the Merlins.
