Speaker Cable for Thiel 3.6

MIT MH-750+ speaker cables on my CS3.6's are the best performers / but / I have not tried Cardas yet.My speakers also sounded a tad bright until I put MIT speaker and inter-connects into the system....Whow, what a difference.

What amp/pre-amp combo are you using?

I used Straightwire rhapsody cables with good results and they can be found for a great price.

I'm using NBS Monitor IIIs on my 3.6s now and it works great.I'm powering them with Krell KRC 3 and FPB 200 w/ EMC1 as source.

Room acoustics and speaker placement needs to be really payed attention to also for the 3.6 to be at their best.
A lot of work I know but once get it, it's very rewarding.
One of the best speakers of all time, period.

Thank you all for your detail and informative suggestions.
