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

NO! The sound of any audio circuit starts with the power supply. NOT the wires going into and out of the supply. To believe otherwise is to fall for the entirely subjective opinions of the untutored!

You could talk with Chris at VH Audio.  He will probably have some good suggestions and can probably build you a high quality cable for less than others charge.

Yes. I have Revelation Audio going from power supply to preamp section and diy/cryo'd Acrolink 7N P-4020 II from power supply to the amp sections of my Musical Fidelity TriVista. Both made noticeable improvements in smoothness and detail.

I use a Triode Wire Labs Ten Plus on my tube preamp to great effect. I find my preamp to be sensitive to power cord changes, so yes I think it’s worth exploring. Good luck.

Audio Magic's custom Liquid Air Illusion umbilical for Modwright (I'm using it between the modified Marantz SA8005 and PS 9.0 power supply) is the best umbilical cable I've heard. It is superior to both the "Truth" and Wywyres umbiical cables.
