Any Herron VTPH-2 Phono Stage Owners out there?

Has anyone recently purchased a VTPH-2? Any thoughts compared to other phono stages costing around the same price of $3,600? That still is a lot of money and a lot of good competition out there. I was also looking at a couple of the Sutherland units (the DUO and the 20/20).

Another concern is that I have a Primaluna Dialogue Premium HP Integrated Amp and was wondering how another tube phono stage would sound with the tube phono stage? Is it better to Mix solid state phono stage with a Tube Amp or keep it all the same (all tubes or all solid state?). My turntable is a VPI Prime with Ortofon Quintet black cartridge. Thanks!
