I’m running a similar Onkyo receiver I bought from Amazon just under 2 years ago in another room. Other than running a little hot, I haven’t had any problems whatsoever. I’ve left it plenty of breathing room, so no big deal. In fact, it’s making me lean toward this as my solution in the living room. I want smaller surround speakers, so they don’t take too much visual space. This looks perfect, and the price is right.
