I'd love to hear this. By all pedigrees it should sound quite good, but alas a tad outside my current budgetary allowance!  Only two settings for MC (high or low) but I guess a few more with the variable impedance MM setting, assuming this is in the SUT circuit. ": 2.5 ohms for MC Low, 40 ohms for MC High, and anywhere from 30k to 100k ohms for MM, adjustable by means of yet another knob, labeled Impedance: a potentiometer infinitely adjustable between those extremes, with 47k ohms at the 12 o'clock position." www.trademe.co.nz/Browse/Listing.aspx?id=2963936568

Looks nice and complicated. 47k MC or go home

Why's that Michael?
Some people swear by higher loads even for MM. And with this SUT combo it should provide a welcome variety of load settings for MC.

That variable loading is only for MM ? Specs say 2.5 or 40 ohm for MC IMHO MC's high and low sound best at 47k, provided the rest of your pre-amplification is up to snuff. A few manufacturers agree Fixed load, fixed gain, simplicity ftw  Some vintage MMs like the Shure V15s like about 100k too. It was ironic that the V15/V, hated by many audiophiles, sounded at it's best in a truly audiophile preamp like an ARC SP11

The Japanese know a thing or two about phono. Use a SUT for an MC. Connected to 47k MM input impedance, this provides the optimal low impedance load for low impedance MCs - in this case 2.5 ohm (Low imped MC) or 40 ohms (High imped MC eg. DL-103) coil impedance MCs will; be loaded down to around 100 or 470-1000 ohms respectively. MMs usually only require a bit of capacitance loading, because of the MM/MI high inductance.

BTW, it's actually a Luxman EQ-500 Damn, this thing has separate prs of SUTs for either MC-LOW or MC-HIGH. SOUNDLABS are the NZ distributor & the RRP is NZ$12k (!) - Citroen knows a bargain when he sees one

Now that looks the business!
Soundline very expensive.

Americans know a fair bit too... The classic ARC SP8,9,10,11,14 preamps had wonderful phono stages - ostensibly MM 47k with loads of gain, When you combine Japanese, European and American sensibilities you end up with a company like Lyra

Yes well Lyra dont make anything worthy of any mention...
