By the way I noticed in another thread of yours with some concerns about overheating, the Stratos series does not even break room Temp.. Its the coldest lowest noise(no hum) amp I have ever encountered with high power and current like this. you could be stunned when touching it that it never seems to turn on.... Also a lot of the times odyssey recommends leaving them on 24/7 they pull no power and create no heat in my experience.. maybe a couple bucks a month on the power bill but I never noticed it one way or the other with them on playing all the time or not used at all...I had Krell, Classe', Forte, Ps audio, Threshold, Muse, Coda, Bryston and probably a couple more I can't think of that I have had... All ran pretty hot, and a couple RED hot after being on for a couple hours when Driven or sitting at idol.. This just does not happen no matter what I do to the odysseys for 24 hours plus.. very efficient solid amps with better part quality than any for the most part that I owned.
