Speaker Cable Suggestions

You will need to experiment.  Even with a LOT of test equipment (and the engineering experience to go with it you can't predict the sound ahead of time).

That is why places that allow use & return exist.

You CAN narrow the field a bit by finding cable with low vs. high inductance - e.g look at Kimber's uH per m specs. and compare to others.

Buy some cheap cable and use against the others to test against it.  Be sure to do the testing blind and see what you find out.

Silver won't change anything except your wallet size, and there is no reason at all to spend a lot of $$ on cable, tho various configurations can change the sound (tho they may not universally improve it).

silver is fine as long as you are not overcharged for it

Yes on used cables and change until your complex load (speakers) give you the sound you want

Kimber tells you the inductance of their cables...

for the record I have some free kimber I used on Vandies; when I switched to maggies inductance is not an issue as the Maggies don't care" about the inductance of the cables (nearly pure 4 ohm load at all freqs.)

Speaker Cables cannot "change" (for better) the audio program, but they can certainly alter a highly complex load (impedance) so that a listener might like the resulting sound better.

No need to spend a lot of $$ to get that however.

Unlike the woo-woo with interconnects, the alteration of sound from speakers with complex impedances by speaker cables is well understood in electronics.

the only help for the OP is to try different (inexpensive) cables from one of the 'rental'/return places until he finds something he likes

no way to predict what sound alteration will be most pleasing

how could speaker cable change the noise level???

duh
