Thread: Tubulus Argentus XP Umbilical Cable

Anyone have experience with this as an umbilical for an XP-22 or any other Pass preamplifier in the X-series?

I am also interested in knowing about experience with Revelation Audio Labs for the Pass X-series?

Are there any other manufacturers?

Thanks

A number of years back I purchased 2 Revelation Audio Labs umbilicals to use with my Pass XP-30, & I continue to use them. In my particular system, they only made a minor improvement, & to me weren't really worth the cost, but others have claimed they made a substantial difference, so YMMV... If it's possible (which I doubt, since they are made-to-order) to get return privileges, you could see what you think for yourself. A heads-up: unless the construction has changed, the cables are quite stiff, especially coming out of the connectors, & I had to move my XP-30 farther away from the rear wall to accomodate them.

Crumhorn,

Thank you for valuable information in several ways. I see your system should have been very revealing of any changes the umbilical made. I have so much money invested in my two systems any additional expenditures have to be worth the expense.

Stiffness of the cables would be a problem for me. I do not want to move my rack any farther into the room. It would also be a major pain to move. I plan to use the two boxes stacked so the bend in the umbilical would have to be a tight curve.

They made a big difference on both of my Supratek preamps and the latest one from July does seem to be a bit more flexible than the one from two years ago. Reach out to Brad by e-mail and discuss it with him concerning your stacking arrangement. You may just have to go a bit longer to get that bend radius you want. My power supplies and control units are on different shelves so hasn't been an issue for me.

I have only heard good things about the umbilical cables from RA.

About 6 weeks ago I had Brad do an umbilical cable for my Phasemation EA-1200 phono stage. Very happy and highly recommended. He even uses the custom Japanese connectors Phasemation use.
