Something in the back of my mind tells me I already know the answer, and asking the question will seem stupid. But here goes ...
When using an external amplifier, is it better to use short amplified runs and long signal cables (from a pre/pro), or long amplified cables and short signal cables.
My application is such that I am using an acoustically transparent screen with 2-3' space behind the screen, which means I could place a multichannel amplifier (for LCR) there as opposed to wherever the equipment rack is.
For thermal considerations of the theater room, the location of the m/amp makes no difference.
I want to say that short amplified cables and long signal cables, but I am not sure I trust myself--not being an audiophile/guru.

Short pre amp, long amp.

Wan, your short amplified cables only hold true in concert venue situations where the preamp signal is balanced. Then you can run 100s or 1000s of feet without loss or hum, but in home installs, you're dealing with unbalanced signals that don't do well over 20-25' runs.

The longer your speaker cable the worse the damping factor gets, so if you don't mind sloppy bass go with long speaker cables. Of course all this depends on the equipment you're using too.

Ok, now there are opposing views. LOL Based on Curt's response (balanced vs. unbalanced), I guess the opposing argument can be true. But I am not using balanced amplification so I'm concluding the interconnects should be short and the amplified cables (speaker cables) should be long.
