Will upgrading Umbilical cord power supply to preamp improve sonics

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.

What are the issues with Revelation? I’ve only purchased their products used and have been very pleased 

I did read before my second post when vendors names were given Revelation audio has had some issues with not shipping items after funds exchanged. I'm going to avoid them if this is the case, don't know if it is true but just what I read online. I guess each vendor is going to have a flavor of its own. Now I'll just weed through that now. Just want neutral if these umbilical produce a signature sound.

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!
