technics sl 1200 gae


is there anyone in America who mods this deck to the level of the English timestop evo sl1200? it's great for rock 45's but how do you drag more finesse out of it for lp's

It’s great for all genres, but the cartridge is more important with GAE if you want to improve it. It a brand new High-End turntable why do you want to mod it like people do with an old SL1200? It's already night and day. Which cartridge do you use?

see timestep uk website. they mod that g version.  that version can be upgraded. considering a purchase to replace my linn. I have older collector records

some mono shibata or decca?  . microgroove mono

In my experience, the issue people have with the G is run in. they take a while. Longer than many but you will be rewarded. I would not do it.
Sure, you can upgrade G, GR or even GAE by changing the tonearm (if you want), but why not buy used SP-10mkII or new SP-10R if you’re looking for higher quality turntables? You are limited with a choice of tonearm for SL1200GAE plinth, but you have no limits with SP-10mkII or SP-10R (except for the very short arms), you can use "10.5 or "12 inch tonearm easily.

some mono shibata or decca?  . microgroove mono

So which cartridge do you use ? 
Decca cartridge is definitely not good for Technics tonearm. 
A cartridge with Shibata profile is good, especially the Victor X-1II
