Do long interconnects degrade sound?

I recently moved into a new home and I would like to use my Krell 400xi intergrated as a preamp for my main speakers in my living room (PMC OB-1). The Krell has a preamp out. Currently the Krell is powering my main speakers for my plasma in my den. In addition, my source is also in my den. Ideally, I would like to use the Krell for both applications which would mean that I would have to run extremelly long interconnects from my amp in the living room to the Krell in the den. I know XLR's would be best for long runs, but is 50+ feet too long for interconnects?

Albertporter...Do you really think 600 ohms is a low output impedance? 600 was typical of tube preamps (12AU7 cathode follower) but I have heard that some modern tube units are down to 200 ohms or less. Solid state typically runs 50 ohms or less.

I belong to the "long interconnect, short speaker cable" school of thought.

Albert...0.17 ohms for a line level output!! Are you sure?
That sounds like the power amp.
