Hi, hope everyone is having a nice holiday!!!! I have kind of converted my garage into a stereo room and have all my vintage stuff set up out there. Five sets of old speakers (Wharfedale, Bose 301, CV DX7,etc.) driven by a not so old Onkyo amp, JVC CD player, etc. My question is---will running this set up in 45 degree temps hurt any of this equipment ??? Does it need to "warm up" for a few minutes before playing?? Or can I just hit the system power button and go for it ??? Thanks.....
