sell away the RS1 and stick with the k701!?! No way.

Thanks for the reply but I think I want something open-backed, not a closed design. I'll always be in a quiet place, and there won't be anybody to disturb.

I'll be using a Denon amp and a Denon CD player, but not a headphone amp, a normal amp for big speakers. It does have a socket for headphones though, which makes me think I can also use it with a good pair of headphones and get good results. Am I right?   If so, my budget for this is $300...
