The Cary's phono stage is better than the Mac's, at least on the C2200 that I had. But I have a seperate phono pre now also, since I have a LO cartridge as well.
The VTL is a sweet preamp, but much more expensive. In that price range I would move to the higher end Cary SLP-05 or the ARC Ref3 (sorry, I don't like the new Ref5 as well).
