SOTA NOVA, HR-X VPI, Technics 1200G recommendations?

Dumb question, but does the power supply have a voltage selector and you've got it set for your correct electrical supply? Cheers,
Spencer

TIME OUT!!! Round over. Everyone back to there corners. I can't bare to see this thread degrade.
@chungjh , I may be somewhat unique relative to this conversation because I've owned close to all 3 of what you're considering. Over the last decade, my turntable has evolved from VPI TNT6HR w/12.5, 12.7 arm to Technics SP10MkII w/ Technics EPA-250 arm and now to Sota Nova Series VI w/Eclipse speed control package & Audiomods Series V arm w/micrometer. 
IHME, you've got two options, the Sota & Technics. Both I would rank far ahead of the VPI. Between those two, a number of valid points have been made, and it's gonna take some soul searching about your personal preferences to reach a decision. 

Sota pros: Great personal support if you need it. That includes custom armboards for any tonearm you choose now and later. Fabulous wood cabinet options, if that's your thing. See my system pics :-) Vacuum hold-down & clamping system is proven, and hard to beat. The suspension is proven and hard to beat. Heck, after trying 10 clamps on my Technics, I ended choosing the Sota clamp. Upgradability to future enhancements protects your investment. Agree that the structural integrity improvements are worthwhile. Mag lev platter is a joy and not the exaggerated quirk some may be envisioning. 
Of course my comments on SQ reflect the arm & cart too...so YMMV, but I find it smooth, effortless, natural with great musicality. It totally gets out of the way and lets you focus on the music. Speed stability is great with the Eclipse controller & tachometer.
Listening to Nick Cave - Alone at Alexandra Palace. It's so spooky and engaging, I keep pausing my typing because it's demanding my attention. 

Sota cons: I don't love the interface UX design of the new buttons. One button toggles 33/45 with short press and also power on/off when depressed longer. It remembers the speed used last. Occasionally I find I've inadvertently switched speed. A minor quibble, but I'd prefer separate buttons for 33 vs 45, like some of the older models. Typical belt drive issues that plague them all; with belt wear over time, speed stability is at risk; the controller offsets this IMHO. 

Technics pros(SP10mkII in Technics obsidian plinth) instant start/stop, high torque, rock solid speed stability. Big, fast, dynamic sound. The removable headshell on the EPA-250 made for easy cartridge switching if you're into that. I had a lot of fun experimenting & comparing many carts when I owned my Technics. If you're into tweaking, your efforts will be rewarded.

Technics cons: Really needs pricey/rare-ish aftermarket(e.g. copper) platter mat to sound it's best. Caution: your final platter height may affect your tonearm mounting as it relates to height/VTA. No suspension. Really needs high quality platform/rack and/or isolation. Aftermarket platter rings are not an option with stock platter, warped LPs may be an issue. Armboard fit/finish varies widely, depending on source. Overall materials look/feel didn't strike me as high end, if that matters to you; it's plain with looks that give no indication of its performance. It's a far cry from the gorgeous variants you'll see from Steve Dobbins or Oswalds Mill. 

VPI - PM me if you want my thoughts. Let's just say I've owned them, set them up for friends, dealt with them over numerous setup/service questions and IMHO, they aren't in this day and age in the same league.

@chungjh, 
While I agree w/ @chakster that mats won't affect sound as much as a cartridge, IMHE, they have a fairly significant impact on Technics tables and are worthwhile.

When I owned my SP10mk2, @dgarretson came over with his superheavy CU-180 mat, a heavy steel mat and we tried both together. I also tried Funk Achromat, Boston carbon mat, and a couple of others not worth remembering. Every one sounded different. Generally, higher mass was best, up until the point where too much started to strain the motor(two heavy metal mats together). When I pondered the ~$800 cost and limited availability of the CU-180 mat, I couldn't justify the expense. Better to go lower cost and invest more in cartridge, etc. That led to...

I turned to Tran Van Tan, a Vietnamese analog machinist, whose TVT Analog Shop makes custom parts for mostly vintage tables. His 2 layer copper/stainless mat was made to meet my requirements for mass & height and was beautifully made for $250. For me a good balance in sound improvement and value. Can't recommend him enough.  He has many photos on his site that will instantly make an impression http://tvtanalogshop.com/   
@chakster with all your vintage stuff, he may be a good resource in the future for you.

Back to your warps question, the Technics platter shape is not friendly to most ring clamps. I gave up on that with mine. Now that my Sota has vacuum and the Sota Reflex clamp, warps are conquered without a second thought. Cheers,

Spencer

@chungjh,

I answered that for you in some detail one pg 1 of this thread,
