Hi Steve,
Yes, as far as I can tell from searching t'net, they take the view that adding the VTA adjuster compromises or effects the rigidity of the setup, but the fact that they provide one now is probably acknowledging the problem created by some of the large (non-Rega) carts.. I conclude from this that if the cart will fit and work well without VTA, then that's the best setup, hence my post, I need to know if the cart will fit. I've even seen advice somewhere that recommends removing the turntable mat for heavier vinyl instead of adjusting VTA.
Back to the cart itself, looks like the best value carts for a great sound for my deck are either the MP200 or the Dynavector 10X5. Before actually paying out for the MP200 I will go and have a listen to the Dynavector at Paul's "Lounge". He had one on a P6 last ime I was there. That also sounded very good as well.
