Recommend a long subwoofer rca?

Monster Cable makes a interconnect designed for sub-woofers. I have not tried it, but they do cables right.

Monster cable is mid-fi. I've had their stuff. MIT destroys them. With their patented passive networks monster can't touch MIT. Buy some MIT off audiogon then go to your nearest audio store (where you can return it later) and buy some monster cable thats twice as much. Then when you've wasted all your time you'll know why there is so much MIT on this site. Because it's popular and great stuff. I started with their lower T3 and have never looked back. Now I own $5000 worth of their wire. Trust me you wont be sorry!

A long run won't help things. I use MIT T2 for the sub, but mine is an augmented setup, so the sub isn't between preamp and amp.

I used to have the monster sub cable. Don't waste your time and money. They are mid-fi. There is much better out there.

This isn't an answer to your question, but rather is an inquiry of my own. Supposedly, balanced cables are better when running long distances r/t noise. Why aren't subs built with XLR connector's on them? Also, are there any XLR-to-RCA adaptors out there that are any good? Do they defeat the purpose of running a balanced cable? Any feedback would be greatly appreciated.
