I have the masterclass PA-4. It surpassed the Trichord Diablo+NCPSU and a Whest 3.0 (one of the special editions), Lehmann black cube and a few others. I use it with the Ortofon ST80SE SUT with a Cadenza black and it's not been surpassed in years. BUT the MM stage on it's own is easily bettered and I prefer a tweaked EAR834 clone and to my ears (so far) is the best MM stage that I've heard for the price point paid. I've heard several Croft MM stages (yes I own that as well), and would say the Clone beats that hands down. The Paradise phonostage (which I own) is something altogether and you really need to get it properly tweaked to get the best from it (Speak to Si of this forum).
