Please help: Speaker wire ?

I second it, MIT Terminator 2 Bi-wire! I'm about to get some single wire ones from Audio Advisor. These are close-out priced, so it'd be foolhardy to miss out. My Terminator 3 ones are beating everything I've thrown at them, including Cardas Neutral Reference, AudioTruth Dragon, Kimber 8TC, Straightwire Virtuoso, and anything Goertz. I'm also about to try Analysis Plus Oval 9, but I don't expect much from it. The reviews I've read on that one seem biased and based on ignorance. BTW, none of MIT's networks contains an "equalizer", and they have zero components of any kind in the signal's path...unlike all of Transparent's cable.

I think changing the wire to cure brightness is a strange approach. Have you considered hanging a rug, tapestry or foam in the room in strategic places to help take the edge off? I highly doubt the wire is the culprit unless you are using very thin cheap junk. Probably the room is what needs tuning. Good Luck!

Tara labs wire is fairly warm and detailed. I have a very live room with glass and hardwood. The kimbers were too bright the Tara Lab Prime helped tame the sound. The JM labs tweeter is very detailed with excellent dispersion-this could be revealing flaws in your amp or source, in addition to the room effect.
