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

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.

Yes, umbilicals pass the Law of Efficacy; it is easy to hear how they impact/improve a power supply. Do not neglect working with the power cord feeding the power supply, as this, too, influences the result. 

I do not find that the umbilical has among the most powerful of influences of cables, but it is distinct, nevertheless. 

I tried WyWires and Clarity Cable umbilicals on the Plus Power Supply for the Exogal Comet DAC. Each has a distinct sound signature. The WyWires was leaner, and the Clarity Cable fuller/thicker.
