Power cords for Audioresearch.

I am using the Taipan Alpha (20A) with my Hydra 8. It is indeed a very "fast" cable. I have experimented with the Shunyata King Cobra, Black Mamba, Audio Magic and a bunch of $3000 PC. In my system the Elrods and NBS were the most neutral. The King Cobra was an eye opener when I tried it several years ago: I was amazed at the improvements in my system. Again, you need to experiment with different cables.

I just bought a ARC VT100 Mk III and tried my Audience Powercord that I have used on my Lamm pre-amp. Maybe due to how the amp needs to be grounded or some other electrical issue but the amp lost it's focus and the solid soundstage that I had with the stock power cord was gone. The stock cord is excellent. Don't mess with success, let alone waste your money.

Anything from Custom Power Cord Co.

I use Synergistic Research Master Couplers on my ARC gear. When placed on my 100.2 there was a extreme difference over the stock cord.
