Aesthetix IO Signature upgrade path?

Addition of a second supply and Full Eclipse upgrade are important to performance. I've owned all of these and listened long term to each level.

The most important thing is replacing all the stock tubes with better NOS, next would be the caps (Eclipse upgrade) and then the second supply.

I don't know if still available, but for awhile Jim was allowing customers the option for Partial Eclipse, which is electrical upgrades but not the new chassis.

Again, having lived with both I suggest the electrical upgrade, finding the new improved chassis pales in comparison along the upgrade path to best performance.

I looked at your system and did not see what power cords you use. If stock you should look into one of the better aftermarket brands here at Audiogon, almost any of them are better than original equipment.

Hi, I was over at Albert's house a few years back. He had some custom made Purist umbilical cords from the power supplies to the phono stage. Ummm wow. We want back and forth once.

This was a monster improvement on this phono stage. They were pricey, but wow. Not sure if these can be made again...

Why not just call Aesthetix?, those people are incredible when a customer calls, Im sure you will find the answer to all your questions. Remember that they build from scratch this incredible units so they Know what could be an upgrade and what not.
