I just did a bake-off in my system of various 'affordable' speaker cable including cables from:
Monster
Pear
Transparent
From time to time i thought i could hear a difference between the cables, but nothing significant, or consistent.
I'm still planning to try Kimber 8TC's, but i fully expect to have the same results there.
My $0.02, any well built cable will do the trick. Anti-cables or something from blue jeans cable would be reasonable choices.
Oh, and my system consists of:
Usher Be-20's
Parasound JC-1's
TACT 2.2xp
Slim Devices Transporter
PS Audio (Modified) GCPH
VPI Scout
Mapleshade SAMSON V2
PS Audio PPP
Assorted Cables from Kimber, Monster, Transparent, APC, and Mogami
