I blew a mid-range driver in one of my Totem Arro's one time when I was playing music loud (so 12-1 o'clock on volume dial) through low impedance outdoor speakers hooked up to the B terminals and switched them inside to the A terminals without lowering the volume. Cost $120 to replace the driver...didn't make that mistake again.

However, if you're in the habit of playing music loud I would recommend getting something like a NAD amp/receiver that has a soft clipping switch for when you play the music really loud to protect your speakers.

The RR2150 is a great sounding receiver but it's not a crank-it-up party receiver, in my experience anyways. [EDIT] On second thought it's probably more the RR2150/Totem Arro combination that isn't well suited for levels loud enough to damage your hearing.
