Ideal SUT for Lyra Olympos cartridge?

I have a Lyra Olympos on a Graham Phantom arm and like this combination alot. I am looking for the SUT that can best match this cartridge. I've got a rather inexpensive Cinemag which simply doesn't highlight the attricutes of this cartridge at all. Price aside, what would fellow Goners suggest and where to get it. Auditorium, Express, Shindo, looking for some meat on the bones type of sound and hopefully some flexibility for future carts.

The ideal SUT for the Olympos? - that was the initial question, wasn't it?
Simple and straight answer: a SUT with a primary matching the inductance of the Olympos' coil source inductance.
Further look out for maximum bandwidth (= lowest phase shift) and frequency extension especially in the low register.

Can you explain this a bit more clearly. I am having a hard time understanding your logic since your first statement directly contradicts your second.

I would expect the coils source inductance to be in the micro-henry range and if the SUT primary matched that not only would it be 6dB down to start, the 2-4 ohm DCR would swamp it and I would be surprised to see anything that resembles the input waveform * turns ratio at the secondary.

Furthermore if you desire low end bandwidth, your SUT primary inductance has to be several multiples of the cartridge output impedance which is for the most part determined by the copper losses in the coils (DCR)
