I'm Curious Kennyb, what power cord did you use on your Quintet? I found the highs pristine and pure of tone. My Quintet is on a dedicated 20amp 10awg line with a Powerport Premier outlet, from there I run an AC10 to the Quintet with great results!
PS audio Ultimate outlet or Quintet?
I've been using UO and UPC 200, both use baluns for conditioning. They both work great but I have limited experience in power conditioners. I use MAC sound pipes for cables. Are the duets and quintets "better" products, or simply different-- is it worth upgrading?
