I also agree with you that 75 F is much better than 90F.
About 8 years ago I had considered moving to Las Vegas to stay away from rainy winter.
But after experiencing 100 F during summer time over there, I had given it up.
I have heat pump installed at my home which can also work as air conditioning.
But I had better listen to music with headphone with the window open .
Stax 009S headphone and KGSSHV Carbon headphone amplifier give very nice sound almost matching my 2 channel audio system.
Thus I do not mind using headphone for 2 or 3 hours during daytime.
