Thanks Ethifi for the advice. There are only two toggle swictches on top of my Cabernet, one is HT bypass and the other is Mute. I did not ask for a Tape Loop in my preamp. Everything is working fine now and the sound was "Amazingly Satisfying & Musical" straight out of the box with stock tubes. The Cabernet is paired with my Plinius SA-102 poweramp driving the Harbeth M20 mini monitors.
I plugged in the smoke glass Genalux KT-66 to my Cabernet power supply unit yesterday evening..replacing the stock Sovtek tubes only, all I could say what Ecclectique said was true, I was very near to nirvana now! After 300 hours or so I will try those NU 350A's. I guess that's it, audio nirvana is reachable through Supratek for common folks like me ^_^. And thank you Slowhand for starting this wonderful thread. You have earned a place in Audigon, Sir!
