I'm very happy with my purchase and can see living with this for quite some time.
I understand perfectly. When you acquire a truly superb sounding audio product/component you cherish and appreciate it. There’s no desire to flip it for something else (Essentially it pulls you off the merry go round). Congratulations!
BTW I believe that you will love your Supratek preamplifier paired with the terrific Toolshed 300b amplifier. You have chosen an excellent signal pathway for your audio system.
