heat

Our system is within a few feet of our wood burner. The audio system has cooling (Infinity) fans where needed. But we went through two TV's. Big screens. A Panasonic and a LG. Finally quit using the wood burner for anything other than coziness. No more heating that room with the wood burner. It's nice in these Ohio winters, but electronics and heat don't mix. At work, we had fans in all our electronic cabinets to try and keep the heat to under 100..And this is industrial equipment...    

All electronics fail first due to mechanical fatigue. This can be caused by several things, vibration, hot and cold thermal cycling and intermetallic formation.

I use covers for each component when not in use.  Easily removed for playing time and easily put back into place after playing time (but only do so after the equipment has completely cooled down).  In order to have a nice look of fit & finish, I went to a local yardage shop and picked out a light weight and nice color of soft velvet.  I gave them the specifications for size that I wanted for each individual component (components vary in size).  They cut the pieces and sewed a box stitch around all edges.  These look as nice as the purpose and function they provide.  And low cost, too.  I hope this and other comments above help you in your quest.

Number one most important comment in the above posts, that you absolutely must pay attention to, is NEVER to play your equipment with a cover on it.  Ventilation during playing time is essential to product life, if not survival, including fire hazard, which could mean your own survival.

even if you play your stereo at low listening levels is it still bad to have covers on your units??
