How long it take before your system/amps sound


...the best. My system sounds the best after 12 hours of playing. I didn't realize this until I inadvertently left my system on overnight. I was surprised how much better it sounded compared having the system on for an hour or two. I have tube DAC and amps, which probably are the reason for long warm up. His really surprised me.

My power company recommends that all audio and video be left on 24/7/365. I was surprised they were so knowledgeable about high-end audio.
For me between 6 min and 1 hr. I have a tube integrated and it takes about 6 min for the tubes to get the bias up. After an hour they are fully warmed up. The difference between the 6 min mark and 1 hr is hardly noticeable.
My amps run Class A so leaving them on 24/7 is out of the question and a waste of electricity. 2 hours on and they are at their best. Still sound good after only 1/2 hr. Pass Labs XA series.
