If the power cords any good then everything its used on should sound better. Ditto conditioners. Otherwise, guess what? They weren't any good to begin with.
Sound quality improvement via simple “isolation”
I’m enjoying music from my internet provider at home using HDMI from my cable box to Oppo 205. Found an old original MIT Z Isolater while tidying up on a frigid (-8 degree celcius) day here in Vancouver,BC. Idle hands are the devils workshop? Decided to try it on the Actiontec ECB6200 my cable provider supplied. I am “very” pleased with the enhanced audio through my Spectral Audio/MIT Cables/B&W system. Picture quality on my ~5 yr old “Pany” may be a touch brighter/clearer as well. Does this make sense? Have any others who listen from their internet provider tried AC isolation/conditioning on the unit provided? Cheers to more refined replay :)
