I am familiar with Wally tools, have used them, subscribe to JR's blog and have a friend who has loaned me his full set of tools. The two approaches are fully compatible and in fact if you can first set up your TT with Wally tools, then use AnalogMagik(the correct spelling of the program - I got it wrong) to fine tune you will get the result more easily methinks. As I gain more experience and confidence with the program I am coming to the conclusion that the key parameters are azimuth and zenith. It is here where the magic (or MagiK) occurs. Of course there is more to it than that. For example, Wally tools did not disclose limitations in two of my cartridges. I am also learning that VTA is not that big of a deal really, meaning it can be way off without adding much distortion. This is the kind of thing that AnalogMagik can show.
