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.

@orpheus10 @bobheinatz  I'm starting to reconsider the RP10.

Is this a considerable step up from the RP8?

Useless you want to spend uber dollars that would need tweaking the RP10 is a killer.
I have a Sota Star Sapphire with an SME V arm. Love the whole thing. The vacuum hold is amazing and the speed is dead on accurate. 

But the number one selling point for me is the suspension. I can literally hit the shelf it sits on with my fist and it will not affect playback at all. This was crucial as i had it on a credenza for years, which was on our wood floors. Kids running around would cause the needle to jump all over the place. Now I could bounce a basketball next to it with no effect.
