Quad 2805 reliablity? Distance from wall needed?

I've heard Quads and enjoyed them but I keep
reading about their reliability problems in both
private and public postings (even in reviews).
I hear about blown panels, etc.
So what't the real story (primarily with the current 2805)?
(I used to have Apogees long ago that proved to be a nightmare with one ribbon woofer that could not be repaired after 3 trips back to their repair facility at the time. A shame because I loved the tonality and
fatigue-free listening.)
And one more question about the 2805s, I keep reading that they need to be far from the wall behind them. My Apogees were fine 2-feet from the wall, so can Quads perform without any fatal flaws at this distance?
Thanks in advance for anyone who cares to answer.
