Speaker Cables With SET Amps

short ones with low reactance(inductance and capacitance).

Many folks are very happy with Auditorium 23 speaker cables with SET amps and/or Shindo gear.

I am probably more budget concious than you but for my SET amp I use Supra-Ply 3.4 and really like the combo..

I had the same question two years ago with my Art Audio Px-25 (6 watt) amp going to my horn system. After a lot of trial and evaluation I have been very happy with Synergistic Research interconnects, speaker cables, and power cords. They do allow the SET- Horn magic to blossom.

The Supr-Ply 3.4 are also a good recommendation.

I've lived with White Lightening cables for 3 years now. I tried to knock them out with other cables both expensive and budget and the White Lightening are still here.
