What does MMC stand for?

MMC is not a Moving Coil type cartridge.

From High Fidelity magazine's review of the, then new, MMC-1 in April of 1983 (the year I bought a Beogram 8002 and an MMC-2 cartridge) they said this about the Beogram 8002 design and the MMC-1 -

"The 8002 uses neither belt- nor direct -

drive. Instead, coils beneath the platter rim

induce eddy currents that cause it to move.

Correct speed is maintained by a quartz -

locked servo system, although you can

deliberately introduce alterations by means

of a pair of buttons below the digital speed

display on the control panel.

Before starting design on the new

pickups for which the 8002 is intended,

B&O set out to determine whether any particular

transduction system has an innate

sonic advantage over the others. To do this,

the company conducted a series of rigorously

controlled listening tests with high -quality

moving -iron, moving -magnet. and

moving -coil cartridges. As we would have

expected, the results indicated that none is

inherently superior to the others: Superlative

sound can be obtained from any of

them.

B&O's engineers elected to use the

moving -iron principle. which has enabled

them to combine high performance. high

output, and low sensitivity to capacitive

loading in an extraordinarily small, lightweight

package. The low mass of these

pickups has in turn enabled the B&O design

team to increase the effective mass of the

8002's tonearm (for greater stiffness) without

moving the arm/cartridge resonance frequency

down into the record -warp range."

I have used the Luxman, Yamaha and B&O amplifiers with the Beogram 400x and 800x turntables. Those were also with MMC 4000, MMC 6000, MMC-20CL, MMC-1 and MMC-2 B&O cartridges. The non-B&O amplifiers had phono selection options and I always use the setting for moving magnet. With a B&O amplifier you obviously don't have to select anything....they are compatible.

It's really neither MM or MC in terms of construction. It's MMC=moving micro-cross, as others have said. Essentially moving-iron, a technology a few others like Grado implement. To get into the specifics, both the coil and magnet are fixed, and the stylus cantilever manipulates an armature between the two that changes the magnetic field.

But more to your essential question, which is setup. Trackbeo has it right: you want to set this up as a low-output-voltage MM. 

Again, to quote Peter from SoundSmith, on their 'high output' (that is, in their lineup, and the B&O clones fall into this):

"They are designed to be used with standard MM phono preamps – 47K Ohms load, with 100-300 pf capacitance loading - to taste. The pf loading will affect the top end sound/roll characteristics. Preferred gain range is 40-44 db." 

Aside from all that—both the Schitt and Bellari stages are amazing (and I definitely want one or the other), but definitely be sure that a now possibly 40+ year old cartridge is up to task. We're talking worn stylus and likely failing suspension. I will say, however, that SoundSmith's SMMC4 is absolutely phenomenal for $200, and I'd budget for a new cartridge before a new phono stage, unless, of course, you don't have one to begin with.

Thank you for all your input. Still trying to decide on the pre amp. 

Mani vs Bellai VP130. The Bellari is a tube amp which I heard brings in a warmer sound true sound.
