I think going from the low-mass Rega design to a high mass VPI would likely do two things: 1) Give you the warmth and solidity you're looking for and 2) Put you in the unique - and enviable - position of being able to speak authoritatively on the differences between the two very different design philosophies.
Where to go next with the turntable
I've been a long time owner of a Rega P7, and I feel like investigating an upgrade, I'm ot sure if I want to stick with Rega (P8 or P10) or try something else? Currently using a Soundsmith Zephyr MK III cart and Hegel V10 phono stage,
What I have now sounds good, but some more bass/warmth would be welcome.
