Yes,premium umbilical cords definitely improve SQ. Pretty much every company makes them now. If you have a favorite power cord, ask the manufacturer. As with power cords, the connectors are as important as the wire. If you’re looking for suggestions, try Cerious Technologies and/or Acoustic BBQ. Several years ago, I DIY’d my own with 20awg pure solid OCC copper. Immediately heard a significant improvement.

I’ve upgraded the power cables on my components for years and always found sonic improvements. For a component the quality of the Pass xp-25 I would look at power cables from KLE Innovations or Nordost to make a significant improvement. There are DIY cables that will also work extremely well - but they are for the more accomplished DIY’er - they’re not just attaching mains connectors to a piece of bulk cable, but they do look more complicated than most http://www.image99.net/blog/files/category-002a002athe-helix-image-power-cable.html Regards - Steve |

Timely thread, as I’ve got a Supratek Chardonnay two-piece tube preamp arriving tomorrow, winter storm permitting. I’ve seen the RAL thread and also hesitate about it being a silver cord, as I lean tonally to the lightly warm side and that’s trickier with silver. Doug Schroeder’s WyWires umbilical review a few years back says he had to modify his speaker’s high end to control for the cord. Maybe that was one off, as I think the WyWires umbilicals are copper. In any case, I’m open to ideas. Thanks, |
