I traded in my 19 1/2 year old solid state Bryston 4bST amp and BP25MC (not a MillerCarbon Edition :-)) pre amp last year with neither component ever having an issue. I turned them off every night and on later the next day. Leaving them constant on didn’t seem to improve their performance. The guru at the hi-fi store recommended I leave my new solid state gear on.
My Apologies to Miller Carbon
You suggested I leave my solid state components on all the time in spite of the trickle charge when off. Today after almost 2 weeks I heard better more solid lows, more air between the instruments, less hash, etc. Miller Carbon also introduced me to the Schumann Generators (2) which I also find helpful. I have very heavy Vandersteen speakers and am deliberating those suggested springs. Thanks MC
