Bob recommend the Pass Seysmour and, actually, he use them on his designs (TG Audio). I changed the flimsy cable that came with my humble TT (a 22ga) for a 14/3 that came stock with a Parasound amplifier. It turned to be an improvement. Now, after changing the plugs on a pair of Audio Magic Xtream power cords I am convinced that it is a major upgrade to any affordable pc. I used a Marinco for one and a Pass Seysmour for the other. The PS seems to be more detailed and with more air presenting a big soundstage. The Marinco was less detailed in comparison but timbre was more natural.
I will swap the plug on my TT and left the inside connection hard wired as is now.
Thanks, Jose.
