The few times I've heard an SME (V) with ZYX (UNIverse) were not impressive. That arm seemed to smother most of what that cartridge can do.
How much that would apply to a 312 S2/Yatra combination is very debatable of course. Wildly different price and performance points.
With respect, Pierre1976's blanket recommendation would only be useful if he's actually heard every ZYX cartridge. I've probably heard more ZYX models than anyone save nakatsuka-san himself, but I'd never make a blanket statement like that. For one thing, several models are VERY different from the "typical" ZYX house souond. Love the enthusiasm though. ;)
