Will upgrading Umbilical cord power supply to preamp improve sonics


H, Is there any advantage to an higher quality umbilical cord. Cables everywhere else make improvements for me through out my system. I've never put much thought into this and don't even know where to buy or if they are even available and if so where? If anyone has done this upgrade was it a large improvement and not just subtle and what was cost per cable? Thanks

I had ARC SP15 ungraded cord before upgrading entire preamp with Black Gate caps and everything else(Ceramic Tube Sockets all caps etc).The upgraded Umbilical made a dramatic upgrade in sound quality hope you can get a top technician to do it.Good luck!!

Indeed. My experience has been every inch matters, and I mean all the way back to the panel, and beyond. How much, and at what cost? There's the rub.

Thanks, I will contact the above cable company's, now I know where to go. I'm quessing like everything else copper,silver and quality of connectors determine sound.
Although they make good products I would be very cautious when dealing with Revelation Audio. Please do some research.

Dont forget the connectors as well. You havent mentioned what type of preamp you own.
