Modwright Phono stage power supply ugrade

I recently noted Modwright is offering an upgrade for the power supply of their PH9.0 phono stage. It adds tube rectification to the current supply.

Has anyone gone that path? If so, how did it modify the sound of the already lovely phono stage?

Thanks

I only had the preamp for a month before I did the upgrade, so I really can't comment on changes in the sound. I upgraded the umbilical to a Triode Wire Labs cable. I think MW was recommending WyWires, but they were too pricey for me.

In my system the Parasound was a bit noisy, although it is very good. The Pass Labs was excellent and very quiet. Both have dip switches at the back, which with the configuration of my system, made access very inconvenient. For me, the MW 9.0x is the best of the bunch. It sounds wonderful and is dead quiet.

The new umbilical is substantially better constructed and I'm sure makes some level of improvement, but TBH I'm not much for cable juju above a certain basic standard.
