I just recived this unit yesterday and so far it sounds great. One question though...on the front panel there is a mute LED with a small hole. It would seem that this should be a button rather then a hole. According to the manual it says to "push" it to turn muting on, but there is nothing to push its just a hole surronded by an LED. The LED does light up when I use the remote to mute it. Also - there is no mention of the remote in the manual. Could it be that there once was a button there before there was a remote included with the unit? I called J&R, where I got it from, and they say that they're all like that. They said I could exchange it if I wanted, but its all hooked up in my rack and I'd hate to pull it apart, ship it back just to get another one with the same thing. I just wanted to check with actual oweners to be sure.
