I bought a duet and returned it since I didn't like the sound of it compared to my 20A HC Ultimate Outlet. I would say it is mostly different and definitely not an obvious upgrade in my opinion.
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?
