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 did it. The difference is not huge, but definitely noticeable, better inner detail and smoother high end without limiting the bass. Surprisingly, it also seems a bit quieter, counterintuitive when you're adding a tube. The best thing is being able to roll the rectifier, which in Dan's amps can tailor the sound. I really like the 5U4GB over the stock 5AR4.

My unit started out as a PH 9.0X, so results might be a little if you have the base model.

mdrone,

I did update the umbilical at the same time, with Dan's in-house offering. 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.
