Metal chassis with black textured semi-gloss powder coating

LCRMKIII has polypropylene film capacitors for the low frequency filter pole. This gets the bass to sound much more accurate.

Also an extra quiet gain setting resistor is used on the front end amplifier stage.

The gain setting resistor is a very low noise, high temperature stability component.

Cartridge loading capacitor is 100pf Wima foil polypropylene paralleled with 22pf MLCC for a more accurate response.

Cartridge loading resistor is a Caddock bulk foil type. This, along with the polystyrene supply capacitors mentioned below, really clinched the sound for an accurate representation of transients and first reflection room sound cues.  

Polystyrene filter capacitors are used on the power supply line feeding each op-amp. These must be located very close to the power pins of the op-amp so that they have a low impedance path to deliver fast transient current. This gives more sense of "air" and allows fast attack instruments better fidelity.

The PCB is 2oz copper thickness to give lower trace impedance

This unit has extra ferrite beads on the power line to reduce hash noise from the wall voltage.


For moving coil cartridges, the LCRMKIII will need a step up amp such as our Copla (check out our other listing in Audiogon) or another type of SUT.

Lounge Audio cannot test every cartridge known today but based on our internal testing and our customers' input, we compiled the list below. Keep in mind that any cartridge above 1.6 millivolts output should work fine and you can always send us a message for us to double check compatibility
