Speaker cable length

Looking forward for your thoughts and pictures.

 With low output impedance ss amps and the typical heavy gauge speaker cables used today, the length is less critical than years ago when high output tube amps and thin gauge zip cord were used exclusively in yesteryear.
 Reasonable differing distances with most speaker cable won't affect time very much, but depending on the cables used might load the amps channels differently.
 Perhaps the best reason to buy identical lengths of speaker cable is to facilitate resale value.
 FWIW, I always use identical lengths.

If you are using 6 or 8 AWG wire and you are not running in excess of 30 - 40 feet, you will not feel any difference in the sound.

Make sure the cable lengths to both the speakers are the same, and do not coil loose cable if there is any.  Bend them and make them run parallel.

@cakyol. My new lengths are 15 and 20 feet of 10g cable. 

Simao,

you will be fine with a 10 awg wire for those distances. No worries.
