will different lengths affect sound

I screw-up numbers in my last post - 54 deg should be 45 deg while phase difference between 10' and 20' cable comes to 12.5 degree (assuming resistive load of 4 ohms).

arctan(2/4) - arctan(1/4) = 12.5deg

Snofun3, Since I am accused of throwing "ca-ca" into the discussion let's cut the crap. If you are not intimately familiar with the sound of a given system these tests mean nothing as do measurements. For a moment I thought I was reading an old Stereo Review Magazine.

No, that's wrong.

You needn't be intimately familiar with a system to hear an "A/B" change that's been implemented.

Actually it might be best you haven't heard the system at all, as the change(s) could be more apparent.

why do people always think the rules and laws that govern physics are suspended when it comes to 'high-end' audio? When you hit the light switch in your house, many lights come on at the same time, although the length of wire connecting them to the line source is very different. If you cannot detect a difference with your eyes, why would you think you would be able to hear a difference?

Sorry, I disagree. You may hear obvious differences in an A/B comparison in any system, but there are subtle differences you will not hear unless you are more familiar with the system.
