different strengths for different cables?

Hi Rustler - maybe I can help. Your question about bi-amping the speakers is valid, but I have to tell you - my experience as well as my customers' experience is that you are going to be less than enthralled with the results, particularly with the Arcam. Yes - in theory this allows you to double the power/current, but in practice, the difference between single channel/speaker and dual channel/speaker is very. very slight. Experiment if you want, but I would do it on a limited expense basis first so you aren't disappointed AND out a lot of money.

many thanks jwpstayman. I'll give it a try, but not at any great expense. Any particular reason why you singled out the Arcam?

Because we handle Arcam, my customers and I have had some experience with this unit.
