Searching any forum including this one is like calling an automated customer service number. It never has the options you’re looking for. Here is my question, I am currently using my Marantz cinema 60 for 99.9% streaming audio. I am running two sets of speakers (one set is hardly ever on) both are powered by a Marantz 7055 amp. So the avr is merely a processor at this point because the speakers are hooked to the pre-outs. However the receiver still gets hot when it’s not pushing anything. Im Curious as to why when there is no load on the avr it would still get hot. \nMy second curiosity is power supply to my home. I thought I was crazy that the performance of my speakers fluctuates depending on the time of day. Early mornings and at night I appear to get more clarity and volume at the same setting. I looked it up on line andI guess it’s a real thing. According to PS audios Paul McGowan it is absolutely an issue in their factory. Of course they sell a power supply to correct that for 12k. I know there has to be more reasonable solutions. Has anyone even experienced this and found a solution?
