12-08-08: LearsfoolNot me. I heard the Rega 3/24 in an all-Rega demo rig and I'll stick with my SL1210 M5G, thank you very much. Some of the "Rega detail" sounded exaggerated and didn't have the solid center image and timbral focus I get from the SL1210M5G.
I would say a P2 easily beats the RM-5. I haven't actually heard the new P3-24, but I have heard the P2 and the RM-5. I would also say it beats the Technics easily. I think that the Regas have a much bigger soundstage, and image quite a bit better as well.
As for mods to one of your SL1200s, I'd recommend you get the tonearm rewire first and foremost, followed by the KAB fluid damper and the Isonoe footers. Get a better mat, at least KAB's 17-oz. Technics "Supermat" or an aftermarket mat from Herbies, Iron Audio, etc. Change out your headshell for a Sumiko or the ZuPreme from LPGear, and upgrade your cartridge to a Denon DL-160 or Audio Technica AT150MLX.
To beat that you'd have to spend a LOT more money starting from scratch with a belt drive 'table .
