I just happen to be looking for a SUT for my friend’s MC cartridge.

By design, this SUT 12.9 x-factor shows 100 ohms loaded impedance to the MC Cartridge. For many cartridges, fixed 100 ohm load can be an advantage. (typical 12.9 x-factor shows 283 ohms to the cartridge).

Rothwell says for cartridges with .3 to .7 mv signal strength; for coil impedance less than 20 ohms. 100 ohms is the ’ 10x formula’ of a coil with 10 ohms.

i.e. my friend’s Goldring Eroica LX .5mv signal, 8 ohm coil resistance. Goldring recommends 100 ohm loading. .5mv x 12.9 x-factor = 6.45 mV signal to MM input (allow for a small amount of signal strength loss).

i.e. my AT33ptg/II .3mv, 10 ohm coil impedance. only 3.87 mV signal; formula’s 100 ohm load. A bit low signal strength for me, I use my SUT’s 20.68 x-factor: 6.02 mV which shows 110 ohms to my 10 ohm cartridge.

Note: no MM Bypass; single input, it’s a specific solution which keeps the cost down.

This Entre ET-100 has 3 inputs, MM Pass, and 3 optional settings

I chose this one, Fidelity Research FRT-4: 3 inputs, MM Bypass; 4 optional settings

My Voxativ’s come next week @ 2G’s, Best 2k i ever spent in this hobby.
Best bang for the buck. You know its hard trying to find a great deal in this hobby,
But I think I found one.

Denon SUT for two arms, 2 settings, and MM Pass, $230. or offer

40 ohm setting

for any cartridge with coil impedance 40 or less. designed specifically for Denon Cartridges DL 103 and DL 103s
1:10 x-factor, +26db
................................................

3 ohm setting

for any cartridge with coil impedance 3 or less
(compared to others, probably 1:36 x-factor, +31 db, verify)

I just noticed this was in the 'speakers' category, sorry.

@elliot, no worries!  Its actually for everything, not just speakers!
