I have a question about an older receiver I have, the Harmon/Kardon AVR 225, which I bought a few years ago and which I have enjoyed immensely. It's powering 5 JBL Studio Series speakers (S38s, S-center, and S26s) and a Parts Express 120w sub. I've never heard the thing clip, despite running it sometimes as high as 5 below reference (almost all the way up) for a couple hours, and it doesn't get hot thanks to a fan in my cabinet. But in comparison, an older Sony receiver my dad has only needs to be turned up to about a quarter of its volume knob to achieve the same volume level as mine turned up nearly all the way. My question is: Could it potentially be harmful to run my receiver at a volume that high, even if there are no apparent ill effects and even though it seems to be handling that level of volume fine? This thing is my baby and has been a trooper, but I'd like to know from you all who know far more than me whether I'm in danger of hurting it. Thanks much in advance.
