SOTA vs VPI (or stick with my Rega?)


I currently have a Rega Planar 3 (2016) with a Dynavector 10x5 that suits me and my record collection (mostly reggae, afrobeat, and jazz) but have been thinking about a turntable upgrade as my vinyl collection continues to expand.

Initially, I considered just a simple Groovetracer subplatter and upgraded counterweight, but am not sure if that is worthwhile. So now I've expanded the search to include a used SOTA Sapphire V or used VPI Prime/VPI Classic. I like the Rega's "PRAT" and no-nonsense design, but would be interested in getting more detail and cleaner, deeper bass out of my vinyl.

Any suggestions/advice/thoughts and alternatives welcome. THANKS!
For reference, my system consists of a Hegel H-160, Vandersteen Treos (non CT), Rega Planar 3, LFD Phonostage LE, and Dynavector 10x5.

If you have a good deal on the table for a VPI prime, I would go for it. You will not regret it . Great table and great company with a team behind it that has the best customer support I have ever experienced.  They really stand behind their products 
Soundwatts is correct. Almost any VPI turntable is the best choice.
The older tables are excellent as is the prime. Their product support 
is excellent and their are many options for small upgrades that improve performance. One of these is the dual pivot assembly which I would recommend you purchase for the arm.
I owned the Marantz TT essentially made by Clearaudio with the Vituoso Wood cart. I never liked the magnetic tracking approach it had. Moved to a VPI Scout 1.1 with a Soundsmith Zephyr. I remember clearly first record I played - I was surprised at how quiet the background was and very little surface noise coming from an old well-played lp. The uni-pivot arm is great as it is unreal how it can track a warped record - with clamp on of course. I upgraded to a MIMC Star cart and was more impressed. If I upgrade it will be to another VPI table with on the fly VTA only, not even up for debate. You can’t go wrong with VPI for the money. I too am a music freak and not a tweaker. 48 years of collecting rock, jazz, blues, and the music that does not fit in categories! 

The "Delux Groovetracer", tone arm wire, acrylic platter, plus the heavyweight will take the Rega to another level that rivals the Sota, but that would also include a new motor for the Rega.
