Rega P10 v Complete rebuild Garrard 401!


I currently have a Rega P3 that I’m generally happy with, but looking to upgrade and I’m in two minds.  Go old school with Garrard 401 or keep with new tech and get a P10.  Both are well regarded and there are plenty of individual reviews.  However I’ve not been able to find a comparative analysis (not really expecting to) so i thought i would ask here.  It would be paired with a Line Magnetic 508ia tub amp and Harbeth HL5 plus speakers.  
I listen to a wide range of music, from classic jazz, funk, soul and classic rock but admittedly i spend the majority of my vinyl time listening to thinks like Bowie, the Smiths, New Order, A Certain Ratio, Chameleons or similar.  
Any counsel?

Congrats on the choice of a Woodsong Garrard,
I have his 301 in the very substantial plinth. I prefer the look and feel of the 301 over the 401.
But I understand the performance is comparable.
My plinth is the dual arm board one. Excellent design and super solid. Chris is clearly one of the most knowledgable and skillful guys, He does all the work himself and is a perfectionist.
My Garrard 301 was fully refurbished by James Campbell  jec@afo.net in Pennsylvania. I also use his unfinished wood plinth for 12" arm.
My arm is the original Ortofon RMG 309. I use SPU cartridges -- Silver Meister MKii, Gold Reference, and a mono.
My phono preamp is Magi Phonomenal. SUT is Live! MC-10 with Hashimoto HM-3.
Overall spent less than $4K without cartridges. 
Just for a reference. 

I’d like to know if it is possible with the REGA 3000 tonearm To changeVTA and azimuth or not ? I hear about spacers for dialing VTA… who can explain to me please ?
