The Rega's don't have a suspended TT sound that I can hear. It's not a suspended deck, so perhaps there is a confusion in terms. Do you mean like a Systemdek (I used to own one) or (shudder) Linn?
The Rega charm is that the whole package is more or less tuned to a certain sound. It's definitely like a cocktail, greater than the sum of its parts. Perhaps that's one of the reasons that the Rega really changes once it's mounted to a wall for example. Again, I think it's a carefully tuned product.
Now, where we can agree probably is the Rega lack a real weighty, meaty sound. I'd totally agree with that. We could talk about this if you'd like, but it's no massive or idler design.
If you're listening to classical instrumental, the Rega is going to shine in my opinion. I'm not sure what price difference we're talking here against a project, but I've seen Planar 3 with RB300 combos for $350-$500 or so shipped?
