I know Regas aren't suspended, but aren't high mass or specially stiff either. I'm referring to that "speedy" yet thin sound which is common -and mainly a sonic goal- for suspended TT manufacturers like Linn. I haven't listened to any Rega TOL though, hence my pointing out that I'd stay away from the glass platter models.
I agree that build quality is very decent for the price, arguably the best in that segment of entry or mid-level decks. But for sound aren't my cup of tea, which on the other hand is one of those silly generalizations "audio people" do, for I haven't listened to every combination of Rega TT with different carts, nor checked everything is perfectly adjusted. I suppose I tend to disregard them for those little things of them like not providing VTA and azimuth adjustment, or saying discs need no cleaning
