regarded but difficult to drive loudspeakers. The MF2300 also uses all polystyrene capacitors in the audio circuit, machined gold-plated OFC input connectors, and premium quality machined output binding posts. 

Solid State in design, with circuits designed to mimic, to some extent, the sound that Conrad Johnson’s tube amps are known for.

This amplifier has an extremely round, full bass, great liquidity through the midrange, and silky highs…just like they said it would have.

The amp is rated for 240 Watts per channel into 8-Ohms and thrives on low impedance loads. Expect nearly 400 Watts per channel into 4-Ohms.

This amp has massive heatsinking for an amp of this power, ensuring that the transistors run cool, which means they will have a longer lifespan.
