Hello T_Bone, when you use a FR-7f then you are on the right track already. It is a very good System. The FR-7fz is not the last version (even when the "z" suggests that), it is a 7 series with a higher output, 0,25mV (easier for a lot of Phonostages, the other ones are below 0.2mV), 5 ohm Impedance, 7x10(-6) Dyne and is like all from this series a blind buy when you can get it. When you want to see the body, go to my System, there is a pic :-)
It has an interesting History, in Japan there a specially selected 7f* units made, too, custom order with specs you can even dream on 30 years later. I listened to one of those, it was the first time where I thought the description "You will eat your heart out" hit me. Unfortunately too rare to start a discussion about that, but I am absolutely sure, when a manufacturer today would build such cartridges again (with different optics) and the Hype which is made for average units today, it would be a revolution.
