I owned a Cary SLI80 F1 signature 2 years and loved the sound. Spent most of the time in triode mode, but needed to go into UL when playing heavier stuff. The unit I had was a bit figgity and had a couple of service issues...YRMV.... I sold it recently and acquired a Audio Note SG88. Complete opposite of what I expected...much better overall in UL than Triode. I am feeding higher efficiency Paradigm Studios and the sound is good either way...but anything group beyond a trio needs UL. LP's via my VPI Ares 2 sound way good. Unit runs cooler than the Cary, and is very convenient to use. Volume control on the remote is too "fast"....other wise overall, a modest but clear improvement over the Cary. Good luck.
