Recommended cables for NHT 2.9

I'm looking for smooth, mellow speaker cables ($200 and under - used) that would work well with the NHT 2.9. I've read that the MIT Terminator is good (and I may get the T2 biwire), but I'd like more opinions. Presently I'm using cheap, old $1.75-ft Monster Cable in a bi-wire configuration from a Counterpoint SA-220. The cables are 4ft long on either side. Thanks for your help ;-)
