SPU Gold Reference vs Silver Meister vs Synergy?

I have heard the following and own all expect the Royal:
1) 85th Anniversary, 2) Gold, 3) Royal and 4) Silver Meister. And I rank them in that order of preference. But the difference is small and all of them do have a house "SPU" sound. Just the different stylus, wires and other small differences in stylus damping etc. Also, there would be some system dependencies, of course.

Dear lhcho,

Sorry for late reply. I mean SPU Gold. Have not compared to Gold Ref. But I think the newer stylus don't sound as good as the older stylus. I also agree that SPU Mono sounds better than DL102.
