I do not leave my stuff on all the time.My amp is high BiAS'd ,but I really do not think it would do harm in shutting it down. I have had it for 12yrs and it has given me great sonics.I do think it does need 20mins to heat up ,but so doies the CDP which I use as a transport now. The CDP gets hotter than my Amp I think.
Having ventilation I do think is important and common sense. Odyssey I think says you should have 2ft. of clearance.I do not believe that stacking is a good thing because of Interference,but I only have 6" of clearance over my amp in order to keep the IC's short between my Passive Pre-Amp.My amp does not use Global Feedback and the shelve above the amp does not get hot so I think it's OK.Any problem with that?
What effect does having amps that have global feedback in their designs state is should be used? I would think that having stuff stacked over amps that use Global feedback would really have a negative effect. What effect does it have if you have something interfering with the field I wonder?
Does anyone have any info on this about Global Feedback designed amp or am I missing something. I do not think I will ever own an amp that uses Global Feedback anyways.All the amps I am intrested in use a DC Servo Loop.
TIA
