Reaching optimal operating temperatures.

Posted by HiFiMaster (A) on October 11, 2004 at 10:42:38

This subject comes from a discussion on another message board. I wanted to get the input of the experts here.

Is there a change in performance after all the internal components reach the highest operating temperature as opposed to performance after initial powering of the system? Meaning: Does your system sound different after it has been on and playing for an hour or so than it does when you first turn it on and start playing?

I like to sit in my sweet spot and listen to music every day after work (winding down, you know). When I first turn it on and listen, most notably the bass is a little thin and laid back, and the sound is generally a little brighter. But, after about 30-45 minutes, the bass is full and tight, and the mid to upper range is smooth and natural. I have noticed this for a while and also expeimented by playing the same track, finding the second time listening (after 30-45 minutes of warm-up) the track is as decribed above, with fuller bass and a smoother upper range.

Am I crazy? Or can anyone else verify this?

I am, BTW, not truly high-end, pretty close for me though.
Speakers: Phase Technology PC 9.1
Receiver: Sony V333ES
DVD/CD: Integra DPC 6.1

I understand tube amps require a warm-up period. Do SS amps also have a warm up period? I am inclined to think they do.

Any responses would be greatly appreciated.
