I have owned a MkII and two MkIIIs. In short, I liked using Herbies on a very solid base for both the player and power supply. I had good luck with both Mullard (smooth and rich/buttery midrange, but good across the board) and RCA Blackplate (a bit more resolution and tighter bass but still very good midrange) tubes. I used a Shakti stone in conjunction with mass loading (brass) on the power supply, and mass loading (Herbies Stabilizers) on the player, including drawer top. I used Herbies tube dampers on the tubes.
Toward the end of my ownership (about 1.5 years ago), the distributor from CA loaned me a new power supply Lector had just come out with. The thing was about as big as the player and had the capability of running other gear, or filtering power. The new supply made things sound slightly "tighter" but also perhaps a bit "drier." I told the dealer that, in my system, the new power supply may have provided a bit more resolution and slightly tighter bass, but that I found it's sound to be less full and not quite as enjoyable overall as the power supply with the stock player. IMO it was not worth the extra cost.
The Lector players are very enjoyable to listen to, over the long haul, and some actually like the MkII with it's TI PCM63 dac chips best. I replaced mine with a MUSE Erato II which I found to be better in just about every way.
