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.
Does room temperature affect your sound?
I am interested in hearing if you guys and gals have experienced a sound difference in your system under different room temps. We are now in a major cold spell in Texas and I don't seem to hear my system as clearly as I usually do. It is a little more subdued. Maybe it's my cold body and ears that make a difference. Anyhow, chime in if you have experienced sound at different temps. More specifically, is there an optimum temp for a vinyl TT system? Thanks.
