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.

IMHO, since you like the PRAT of the Rega, stay with that or a Linn LP12.

Though quite fine turntables you will not get that from SOTA or VPI. This based on having owned, and listened to, many VPIs and still owning an SOTA sapphire.
@mulveling thanks for your in-depth response. It is very helpful and much appreciated. All that you mention about the SOTA is what I am looking for in a TT. I am not interested in analytical listening, and do not shy away from the warmth of vinyl as my SS amp is incredibly neutral and they seem to balance each other out nicely. 

@viridian thanks for your feedback as well. I am interested, what about the SOTA Sapphire do you like, personally? I think it’s telling that you still own one.
Oh, the SOTA has a nice solidity to the sound with good body and saturation. It’s more like an idler in that sense, only quieter and more serene, with less punch. My LP12s have better PRAT, as did the Regas that I’ve owned in the past.

The SOTA is, pretty much set and forget which is another blessing. they were originally voiced with the later SME arms, so those are a good choice. I use a Well Tempered, which seems to be a good match as well.
@viridian The Rega has better PRAT than the VPI? I hadn’t heard that before. Very interesting.

Can you elaborate more? (Not hating, I am in the market and listen to punk and faster music so PRAT is important to me).
Take my opinion with a grain of salt, as it is just that. Yes, subjectively the P3, P3-24, RP3 and RP6 were all pacier than the VPI and SOTA tables, that I have heard, and owned. And I won’t try to assign a reason as some feel the Rega turntables run fast (mine did not with an LP playing and the stylus in the groove), or that being bass shy causes the effect (more probable, IMHO).The LP12 has more PRAT yet. I would love to hear an RP10.

Unfortunately, PRAT is a rather one dimensional look, and the VPI and SOTA tables have some fantastic, unerring, strengths beyond their Brit competition. PRAT is just not one of them.
