I'm pretty happy with what I have, but I'm wondering if I'm missing something. I have a Cambridge Audio Azur 651R AV Receiver.
I stopped quoting right there because we found your problem. There are only a few things in all of audio that might be worse than a receiver. Patch cords and power cords shipped free in the box are two of them. But only if we're talking receivers. You indicated AV receiver. There is nothing in all of audio worse than an AV receiver. So no point quoting further.
So yes, reubent is right. Hedging a little probably trying to be nice but what's the point, AV receivers are garbage, might as well just come out and say it. Within the first minute you compare one to a similarly priced integrated you are gonna know it anyway. Might as well just save time and be straight about it now.
So go get your new stereo integrated. Then, about those power cords.....
