Operating temperature of CD players?

Mostly, yes, it depends on the unit's construction and its immediate surroundings. Do 'dedicated' CD players in a seperate case do this? Typically, no, but it depends on the surroundings. If the CD player is in a cabinet with the receiver or on top or another unit, it will heat up. I was previously using a fairly old/cheap CD player in a seperate case that didn't play MP3s, and I don't recall the CDs ever being noticable warm when I opened it. Isn't this bad for the CDs? I have heard that they will deteriorate when exposed to temperatures over ~80 farenheit for long periods. Is this true? Or is it more true of CD-Rs than 'pressed' CDs? The unit is quite well ventilated so it's not a problem that can be fixed my moving stuff away from it. I need to decide if this 'feature' is something I would get from most any 'bookshelf' stereo or if I ought to return it. It's not a problem, but if you are really concerned, add a small fan to cool the unit. (But this will introduce its own problems such as noise and dust.) It is possible that storing your CD's at mildly elevated temperatures for years may decrease their ultimate life, but I think we will need a few more decades of experience to know exactly what that decrease might be (if any). 100 degrees is somewhat lower than the ambient temperature in some areas (Such as Europe this summer). So far there haven't been any reports of "wilted" CD collections. That said, there is a group of audiophiles claiming that CD's subjected to a cryogenic process sound better than regular CD's. I don't think they researched the effect of their process on the ultimate life of the discs or considered the possiblilty of repairing potential damage done by playing CD's at 100 degrees. ----------------------------------------------------------- SPAM: wordgame:123(abc):14 9 20 5 2 9 18 4 at 22 15 9 3 5 14 5 20 dot 3 15 13 (Barry Mann) [sorry about the puzzle, SPAMers are ruining my mailbox] ----------------------------------------------------------- |
