Shorten my speaker cables?

The old rule of thumb, is that given the choice, shorter speaker cables are more critical than shorter interconnects to the amp(s). I am in the same boat, as I've been using the same 12' speaker cables for many years, but l have finally gone to mono block amps and now only need 6'.

When going with shorter speaker cables that are keepers, make sure that your amp(s) is in its final resting place. My last tweak for my current system will be the replacement of most of my cables, so I want to be done with moving gear around.

I have Satoris (shotgun) for a while and they are wonderful.  In comparison to my previous AQ Indigo they have fuller lower midrange (male voices, cello), being faster with silky smooth trebles.  Much better overall.  I considered Oval 9's an read many reviews.  Satoris supposed to be a little better while Oval 9s are a little bass heavy.  I would definitely take advantage of shorter cables, but wouldn't cut.  Sell them - you can get better shorter cables.  Re-terminating can also be difficult.  Satoris are very thick (I think it looks cool) since they consist of bunch of individually insulated strands in helical twist on hollow tube.  One of the strands is not solid, but stranded (tiny wires).  I removed original bananas, cleaned, crimped spades and then soldered. 

I also replaced AQ King Cobra with Acoustic Zen Absolute (both 0.5m XLR).  Absolutes are more refined, have better resolution, blacker background etc.  Overkill for my modest system, but it was very good price.  

Oval 9’s are very easy to re-terminate and sell the rest of unwanted length. You will need heavy duty crimping tool.

The other thing that will help besides going to shorter speaker cables is to go to longer interconnects and move the gear away from in between the speakers. Cheers,
