My experience leads me to believe that leaving my SS gear on all the time is crucial for best performance. Anecdotal evidence: coming back from a 4 day weekend w/ my gear powered off, it took at least 4 days to sound good again. That convinced me to leave them on 24/7.
However, in the February "Stereophile" review of my amp, the reviewer stated that the amp sounded good after 20 - 30 minutes and didn't improve after that. Oh well.
Also, longevity doesn't seem to be an issue for SS gear w/ literally thousands of on/off cycles. My old Hafler and NAD SS gear were always turned on and off. They're both still going strong at 25 years and counting.
