Charlie,
I hadn't factored in the cable cost, and yes, 0.5m would be too short.
I have relatively efficient older model 8ohm ARs (95dB front towers, 94dB center and 91dB rear bookshelves(2) + Paradigm PS1000 sub). The room is a finished basement approx. 25'x30'x8'. I typically listen to music at low to moderate volumes but do like to listen to SACD/DVD-A music loud on occasion --- I listen to some older CDs loud but find a lot of the newer one's don't sound very good at loud volumes.
Ragnar,
I think that's just what I'll do
Regards,
John
