Which VTL is what matters? VTL 450 Mk3 is in a different league than the earlier product. The original 450 should not be compared to the 210. And the S400 is not a 450. I much prefer the new 450 Mk3 to the earlier versions and the S400. But when you compare to the MB750 it is different. Then the additional power makes a difference, but the improved circuit of the 450 mk3 gives it an edge in detail and transparency.
For me ARC always sounded like SS while VTL sounded like great tubes.
