I think they compliment each other pretty well. You will need a shim between the headshell and the cartridge in that the Rega cartridges are very short in height and the Technics VTA will not go low enough to accommodate them. Regarding the phono stage, the good news is that the output of the Exact is very high at about 7mV, so you won't need a lot of gain, and noise won't be a problem even with relatively high noise, all tube designs if you choose to go that route.

Does anybody have any experience with this cartridge and tone arm combination? The technics will have the KAB fluid damper, and sumiko head shell on it. Also, how nice of a preamp would you need to make this combo worth the retail price tag of 595.00 for the cartridge? Currently, I have the fairly modest Cambridge Audio 540p.
