Best power cord for Subwoofer?

Since you already have Synergistic Tesla series cables, go for the T3. That is what I did and it was a big improvment over a few others I tired. Demo it first through The Cable Company.

I too have a SVS Ultra. I have tried a lot of PCs, and really like the Tek Line Cables microRefence. He advertises here

To Joeyboynj: I think I will take my T3 from my amp and put it on my sub. Thx.....you seconded that notion also from Ryan at S.R.
I'll put the Precision AC on my amp, and put a T2 on my QLS. ALSO: I do have some pics for you of the QLS. I'll send later tonight...
ALSO: is the Reference Sub cord the Tesla series??

Barcardi, A T2 on your QLS? Is the QLS running your whole system? If it is, the T2 may constrict because it is designed as a source power cord and not for high power applications. The best PC to place between the wall and a power conditioner in a full Tesla system is the Precision AC as you already have it. Put the T2 on your amp and T3 on the sub and then switch them just to make sure you like it.

Also, Synergistic makes a Tesla Reference Sub cable as well. It will say Tesla on it. Go to The Cable Company website and take a look of the list of items they sell for Synergistic. It's easy to compare names.

I am using 2 runs of Tesla Reference Sub cable on my sub and also have a T-3 PC on it. Sounds really nice in my all- SR system (it better, for what it costs!!)
