RCA cable lenght

Mwiliams; Is it not possible to put the monos next to the speakers? - that seems to be the layout of choice most of the time. Mine are about 2 feet from the speakers while the interconnects are about 7' away in either direction without any issues. Just a thought.

You can do it, you may get a little degradation but shortness of speaker wires will compensate for it. I have run ones 6M if my memory is correct, I used good cable and was quite happy. This is a vary contentious subject as you will probably see.

Depends on the specific devices but, in general, it should not be a problem. I run 10M interconnects without any issues.

There is no hard and fast rule about maximum interconnect length, because it is highly dependent on both the output impedance of the preamp, and the capacitance of the interconnects. The lower the better in both cases.

If you choose interconnects with capacitance of say 20 or 30 or 40 picofarads per foot (pf/ft) or less, and if you have a preamp with an output impedance of say 100 or 200 ohms or less, you'll be fine. If both parameters are significantly higher than that, upper treble rolloff may result.

Also, the resistance of the path through the shield from one end to the other needs to be low, or 60Hz hum may result. Most quality cables should be adequate in that regard, but the only way to know for sure is to try it.
