If U stick to unbalalnced: I wouldn't dare contradict Sean on the possible circuit danger resulting fm a long IC :>), but I did do just that w/out any problem. HOWEVER, it is logical that the smaller signal emanating from the pre is way more vulnerable to interference, loss, and other goodies Sean identifies, than the stronger signal that comes from the amp.
In fact, using unbalanced (as recommended by my pre manufacturer) @ 1mtr and amp->speakers 6 + 6 metres (i'm bi-amping), was better sounding in my system than the other way round!
