Aesthetix Callisto signature or ARC Ref3

I will be pleased to know if you have heard these two preamps, the Aesthetix with the 2PS, and which one do you prefers to be used with SS amps.
My other consideration was Audio note Kondo M100 mkii or the 77, but they have a stratospheric prices, do you think that there is so much sound quality difference between these two preamps and almost the kondo M 100mkii?

I suspect the Kondo will be hard to beat.

But the price for kondo is $60.000(M100 MKII) and M77 $40.000, against $10.000 for the ref 3,also I ask: may I improve the sound of REf3 with betters caps?

You may replace the 6550 tube in the PS with NOS TungSol Black Plate 6550 from the mid 50s (or second tooling Gray Plate from the 60s), and 6H30 tubes with some NOS types from early 80s.

I'm awaiting NOS TungSol Black Plate 6550 tube myself as we speak, so I will let you guys know.
