Ok ,so I searched,found nothing! Now, has anyone perceived a difference in the performance of their system with respect to differing weather conditions?Speciffically,I could swear that when we have a really great day here in Florida as today was,(low humidity in the 30plus per cent range,Temperature high 60's to 70)I perceive as I did today a marked improvement in sound quality.It is difficult to articulate,but it is the 'you know it when you hear it' change.That is opposed, obviously, to higher temperatures and much higher humidity numbers which of course are more common,even in winter.Maybe it is a 'placebo effect',but I have never thought of myself as particularly prone to such,and have even had attempts made to be hypnotized,unsuccessfully.I see that as a good thing btw.Hey,muchas gracias in advance for input,or not.
