Wife is remodeling - spkr cable recommendation pls


My wife is remodeling the house. Works out OK for me, new plasma, HT stuff in family room. 2-channel has moved to another room. However, due to new set up, I now need 25' speaker cables from my MF A300 integrated to my B&W N-804's. Cables will run from closet location of electronics (new dedicated power line) through floor, across basement and up through floor again to speakers. Locating amp closer to speakers (or basement) not in the cards.

I had been using MIT Terminator 2 bi-wire and was reasonably happy though I haven't tried anything else (except Radio Shack 12 gauge from old lo-fi system). I was hoping to spend around $500 or less. Any suggestions would be appreciated.

Since you'll be going in wall, I suggest you stay with CL4 (or is it CL3) rated wire. Check out the Kimber in wall at Audio Advisor. IMHO, you don't need top of the line cables for HT rear surround duty. Good Luck! Mike.
Guys, I think he's looking for cables for his 2-channel setup - not cables for rear surrounds.

Wstritt - If I were in your position I would take a look at Signal Cable. You should be able to get a good pair of shotgun bi-wire speaker cables at that length and still come in under your budget.

Good Luck!
Jetkitty is correct that I am looking for cables for the 2-channel but I appreciate everyone taking the time in any event. Thanks to everyone for the suggestions. I have a few more options to look at now that I hadn't thought about.
