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.

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.

Barcardi, what Synergistic is saying is to only use the QLS on active MPC adaptors. Not the whole system. Also, Synergistic mentions that the QLS was created for Tesla actively shielded systems that decided not to go the upgraded route of a quattro. The quattro is currently the top of the line, since the Enigma is all sold out. Ted has mentioned in another tread that they may be working on another model with tubes in the future.

I compared a PS Audio Statement SC vs a Synergistic T3 on my Rel subwoofer. The T3 was much better. Deeper more accurate bass, better reverb times and resolution. PS Audio PC's are no slouch on subs, I use one on my HT system sub. But the T3 is more musical and 3 dimentional and mates perfectly with a all Tesla cable system.
