Length of speaker cables

Hi Steve 0713.  In general, speaker cables are more critical than interconnects. So, if you can, put the monoblocks very close to the speakers and use long interconnects to feed signal to them. You can easily make good interconnects using Belden microphone wire. You should hear a noticable improvement in addition to the serious improvement the new amps will make. Keep Smiling.

Shorter interconnects and speaker cables are theoretically better sounding than longer ones, and longer power cables are better than shorter ones (just don't makes loops out of excess cord - it creates a magnetic field). Also, don't run the cords close and in parallel to each other, try to have them cross, if unavoidable, at 90 degrees.

Whether or not you can hear the difference (all other things being equal) may be questionable, but doesn't this business rely on the theoretical, specifications, etc.? 

Psychoacoustics - if you think it sounds better, it does. 

Morrow is the best I've seen. Very good prices, usually there is a sale, or a 40% discount if you upgrade from any cable. They have a very long break-in period so be prepared.

I had mono blocks & went to used Anthoney Gallo 3.1 Speakers with 8 foot high end Silver Plated O2 Free Twisted 12 Gauge Copper Cables (Cables came with the speakers).   I was underwhelmed with the highs, especially Cymbal Sheen.

Later, I built 3 foot long, 5 Strand Pure Silver, (Just under 12 Gauge Total) Teflon coated Speaker Wires & connected them directly to the Mono Blocks.

WOW did the highs ever Jump out & Cymbals had that Sheen, just as in real life.

I do not know if it was the Length or Silver, but the combination was spectacular!. 

Cut in half and biwire.
