I have the 204 and was an early purchaser of the ModWright PS for it. I did not compare it to other LPSs though, so can’t say how that would be. I decided on the ModWright based on Dan’s excellent reputation as a designer and the fact that he was designing the PS purposefully for the Weiss. The fact that it was an aesthetic match was a nice bonus.
I have been very happy with the purchase. Improvements in soundstage and imaging, and somewhat surprising to me was also an improvement in timbre. I did write up some of my thoughts about in the summer if I recall.
While I can’t help with comparisons, I can say I am a happy customer. Also, ModWright in general was terrific to deal with.
