SPU Gold Reference vs Silver Meister vs Synergy?

Anybody listened to those Ortofon SPU cartridges?
How are they different?
Here are the current SPU G lineups, in the order of their price.
95th > Royal GM MKii > Synergy GM > Silver Meister GM MKii > Classic GM E MKii > Classic GM MKii.

Ortofon does not produce any Gold SPU cartridges. Where would SPU Gold reference belong in its price?
Gold reference was speciality product as 80ties anniversary or the 90ties anniversary so to speak....main difference is the use of the replicant 100 stylus ....as david said you can fill page describing each of these cartridges, as each is very different in sound, but you can say for sure that all are VERY musical cartridges. There is also Japan only limited number SPU Spirit which for my $$$ is one to look for......
I have both Gold and Gold Reference. For me the SPU Gold (with silver wire) is way better than the Gold Reference. Though I haven't had a chance to listen to the Meister and Synergy.
Prcinka, Do you know what makes the SPU Spirit special? The special addition SPUs I own have a different balance than the Classic, the goosed the high frequencies for these cartridges, without that I'd like them a lot more.

if you go to theartof sound forum and type there you can find the whole chart for any SPU cartridges under the thread by "fordy" SPU Spirit...The wire is 8N copper for the coils...
I recently spoke with someone who knows SPU's, and he summed up the following 3 SPU's this way:

SPU 95th

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.
