Does your system sound better in the winter?

Summer is not a good time for critical listening. Between the air conditioner noise, brownouts, cricket and cicada noise, eating outside, etc,-why bother. Who wants to heat up the tube amps with the a/c blasting away? Most of what little summer listening I do is thru headphones in my 2nd system. Even then I put my Grado's aside and use sealed headphones to try and drown out the AC noise. I have finally found a decent pair of sealed headphones-Ultrasone HFI600.

Yes, I have noticed better sound quality in the colder months. Here in Houston I still listen frequently in the summer, but with my heat generating all tube system I can cool the room simply by opening the windows.

Phild you might consider a Tripp-Lite LS 604 line conditioner ($138.65 with $10,000 insurance). This device will bring voltage as low as 87 volts up to a minimum of 107 volts. A maximum of 140 volts down to a maximum of 126 volts.
Don't risk ruining your stuff from a brown out.

Could it have to do with the slightly denser air at the cooler winter temperatures? Since sound doesn't travel in a vacuum, going towards the other extreme could mean better transmission of sound. Seasonal humidity differences might also make a difference.

Or maybe your earwax is softer in summer. Or maybe your outer eardrum cells are drier and less pliable in winter. Or maybe the coclear fluid in your inner ear is slightly more viscous with the cooler temperatures. Or maybe when it's hot you have different bloodflow patterns in your ears. Maybe snow and ice act as ambiant sound absorbers or diffusers.

My best guess is that it's just generally quieter and your equipment likes the temperature better.

It is not only the summer noise. At least in my case, the power quality is worse in the summer. All summer I have had to endure a persistent and loud buzzing from my system. It is so loud I really can't listen to it during the day. And no, it is not a "ground" problem. From the hours of 2:00 AM to 5:00 AM my system is dead quite. It is also quite though the rest of the year.

I hate summer!
