Speaker Cables?

First of all, you need to give some indication of how much you are going to spend...but there is some " Lab Cable" at www.psaudio.com 6 gauge, ,looks like its worth checking out, but will cost over a grand. Which i am sure is too much. also Kimber Kable 8tc is good stuff. but i dunno how much u wanna spend

I use Carol silver plated copper wire. Bueno. Best bang for the buck. Get 12 ga. If you want feedback read its reviews in audioreview.com

As for my system, my speakers are pretty revealling (JMlabs). The silver plated copper wire made an amazing difference. Same benefits as stated in the Mappleshade catalog about its silver plated copper solid core.

Try doing a search in the forum archives. This subject has been covered previously on more than a few occasions. I would only add that you really DO need to pay attention to cable spec's when doing LOOOONG runs such as yours. Too much capacitance and the amp oscillates. Too much inductance and you have NO upper mids and treble. Any long run of wires can also act as an antenna, so you must also take this into consideration. Look for an "anti RFI" design. Sean

MIT is great for long runs. Please refer to my comments in archived thread:
