“I learned that the M-900u uses v.4.0 of Luxman’s Only Distortion Negative Feedback (ODNF) circuitry, which they say reduces high-frequency distortion. Luxman says that the amp’s circuit boards are creamy white because they don’t use a green solder mask, which the engineers feel mucks up the sound.
