It's a matter of taste and NEVER about which one is better.
Some people (including me) prefer the Rega over the VPI because of the richness and musicality of the Rega compared to the "revealing" nature of the VPI deck.
Please note that "revealing" does not mean harsh or over the edge. It just sound more analytical to my ears, nothing more, nothing less.
I owned the original Scout when it first came out and it sounded superb with my DV 10xGold L/DV P-75 combo. Cannot comment on new model but I'm extremely satisfied with Rega now.
Luckily I have a great friend who owns a local dealer. I visit often allowing me to listen to great tables for long periods of time.
Based on multiple listening sessions, I would only upgrade to a Townshend Rock 7. Again, a matter of preference.
It all boils down to taste and synergy?
