Got it BC Danny Ritchie from GR Research recommended replacing the stock power cord with a decent one. So I tried it on my PC. He has a creative sound card with a Saber DAC. Respectable. Nothing fantastic. Emotional bas-x 100 amplifier, X-LS encores that have been slightly improved and two Infinity R12 subwoofers. The difference the power cord makes is noticeable. I played Tools Chocolate Chip Trip. It sounded fine before the cable change. After that it sounded better. A bit more detailed, but the craziest thing was that the soundstage was left behind. There is a drum sequence that literally surrounds you. So, two speakers and you literally have surround sound. You can point at the reels as they move from right to left, alongside and behind you. real journey. For $30? Yes. Costs. Note. It's a thick cable and it's a bit stiff. Make sure you have a little extra length just in case.
