And equidistant and properly terminated. Even if that just means tinning the ends. Corrosion, even surface, is the enemy of electron flow with copper and aluminum. If possible if you don't have a shielded or braided design, try to keep them from running too near power transformers and with tube amps output transformers. And try to keep them from coiling over themselves ie an antenna.

And have fun!

I had a wire run of 30+ ft at least to run my Onkyo AV and mostly for XM news radio thru JBL 130s. And some music.
I just re arranged my placement and cut the run down to about 10 and 15 ft resp.
I really can hear a difference even in a talk radio format. I also made sure I didnt leave excess wire on the ends at the AV clips.
I was surprised. Just thought I would mention it for newbie installs.
Keep the run short..

You don't say what wire gauge you are using. That is the critical thing.

A 30 foot run would be no problem if you use 12 gauge pure copper wire.

For 15 feet, you should be using 14 gauge pure copper wire.

If you are not, you can get Monoprice #14 pure copper speaker wire for $13.26 for a 50-foot roll; #2748.

Bare wire is the best thing for spring clips, but you should cut it off and re-terminate it every year or two to remove any oxidation at the ends.

Hard soldered ends are no good for spring clips, but they are fine for binding posts.
