It sounds like the opinions are pretty strong in favor of moving gear out from between your speakers. A potential negative of course, is going to a real long RCA cable to do this. I don't want to sidetrack the thread w/ this, as we have all either had experience or read about the variables.
They say under 3-4 meters is Ok, but it also depends on the preamp's ability to drive the longer cable....
Many people seem to just simply position their gear lower, which is IMO,less practical if you are running a turntable.
There is also the option of longer speaker cables. Again,
there are variables involved here too. I would think 12-15
feet would be necessary to make this work, and still look
good. The SC length needed certainly depends on if you run a stereo amp or monos. This setup would allow all gear, including the amps, to be placed on a different wall.
I have heard that Auditorium 23 speaker cables sound does not degrade in long runs. I am not suggesting that this does not hold true w/ other SC manufacturers.
