Does room temperature affect your sound?

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

Well OP, I go outside flip up a hoodie and come back in.. Stereo sounds BAD.. Flip the hoody back, take my hat off. Perfect. I forget sometimes.

The voltage thing is interesting, I never though about that in the winter. I guess folks do heat homes with electricity. I use valve amps and have for 30 years. I just have an old fashion floor heater that is Natural gas fired.
It stays at 60-62.

I keep the humidity high enough to stop static snap, but no problems with finishes in the house. Humidity stays the same here.

I guess were talking air density, sound flying through fog sure sounds bad.. Happened in SF a couple of times.. The fog would roll in an just ruin a concert, muffle the heck out of the sound in open stadiums, or Amphitheaters.

Regards

Electrical conductivity improves as temperature falls. Superconductors have to be frozen. As fall as sound production by speakers is concerned,  I would think altitude might cause a greater change in a speaker's characteristics than temperature as air becomes less dense and barometric pressure drops. If you go high enough you get no sound at all.

No, but humidity does.  And if you're running your heat non-stop, you're going to end up with very dry air.  Unless you have a humidifier hooked up to your HVAC.

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.
