Does room temperature affect your sound?

I lived in Summit County, Colorado for 10 years, so familiar with cold too, but dry cold up there, humid cold down here. Anyway I think the change in sound may be more due that I turned off all my equipment for the last 3 days. I usually leave my preamps always on. Will find out tomorrow since I left them on again. And MC, my thermostat was set at 62 degrees since I was gone for a few days. Getting used to your strange sense of humor.

That would make sense, it's probably part of what I am experiencing.

Now, there is a lesson in comedy! Thanks  oldhvymec.

Most of you guys are really helpful. Much appreciated. I have a voltmeter and will check it out.

Doing a listening session now. Kate Bush, Never for ever album, Holland original vinyl press, much better than U.S. one. Sounds as good as ever, uber clarity, space, beautiful. Room temp set at 65, comfortable enough in my heavy sweats and zero static issues due to too much dry heat. I truly believe now the fact I left my phono preamp and preamp powered on since yesterday is the difference. My Halo Parasound 23+ power amp gets turned off each time without any sound consequences as recommended by the manufacturer. But I shall not turn off my preamps anymore unless worried about lightning strikes. Letting those preamps get cold does affect the sound in my system. BTW, power is not an issue in cold heavy demand weather, measures real well in my dedicated house of stereo at 121 volts like any other time. I think this was a worthy discussion even if MC chose to ridicule it. And I do pay attention to the many things he talks about that he is familiar with. They are very instructive. Unfortunately he has a way to demean things that may not be familiar to him. Keeping an open mind is the best way to progress. Thanks to all of you audiogoners who responded.
