M2X with JFETsThe M2x is based upon the Nelson Pass First Watt M2 Amplifier. However, the first "buffer" stage of amplification has been placed on a removable daughter board, making it extremely easy to swap in different first stage circuits. A total of five first stage circuit designs are provided, and naturally one of them is the Nelson Pass First Watt original. Read the M2X thread on diyAudio to learn more and join in the discussion. The M2x is a Push Pull Class

The MP7770 amplifier has quite low distortion by itself (I measured about 0

mostly in musical instrument applications

If you choose to solder your speaker connections to the binding posts

Some information from Cardas is below

but these are not readily available

and much more into 4ohm

Neutrik XLR input jacks

but it's perfectly at home in the 'big rack' as the heart of a high-fidelity audio system

If you are a big believer in single ended class A
