SPU Gold Reference vs Silver Meister vs Synergy?

I recently spoke with someone who knows SPU's, and he summed up the following 3 SPU's this way:

SPU 95th
SYNERGY
ROYAL

He said the SYNERGY had more of the classic (old school) sound while the 95 swayed toward the more modern sound relative to SPU's. The Royal was somewhere in the middle of these.

Please do your own research, but those were his findings. I know the proper arm is important, as it is with any cart.

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.

Thanks for all comments.

Ddriveman,
Does Gold mean SPU Gold or SPU Gold Reference?
Someone suggested that Gold sounds better than Gold Reference.
My experience of SPU is SPU Mono, SPU GM e MKii, and SPU Gold Reference.
SPU Mono (MM, high voltage) sounds better than Denon DL102 mono.
GM e MKii sounds worse than other Ortofon MC cartrdiges I've owned, including MC20, SL15e, and SL20q.
Gold Reference dows not sound better than SL20q to my ear with my systems.
SL20q is with Clearaudio Bluemotion and Ortofon MCA76 phono MC amp. Gold reference is with Garrard 301/Ortofon RMG309 and Budgie Cinemag SUT.

I would look for better SUT for the SPU cartridges....It may be more $$$ but you will gain a lot....you may start with Patridge 7834 or Ortofon SPU T 1....

I am using a Bob's Device SUT with my SPU Gold. The SUT does give a significant improvement.

I would like to try the Auditorium Hommage T1 SUT but it's too expensive....... :-(
