Elegant and Practical
With its elegant all-alloy casework, the Masters M23 HybridDigital Stereo Power Amplifier is as pleasing to the eye as it is thrilling to the ears. The M23 has the same quality of construction for which NAD’s Masters Series is renowned. Rigid panels and magnetic iso-point feet provide a rock-solid foundation for the M23’s multi-layer circuit boards and intricate internal construction. Truly the M23 represents a new pinnacle in power amplifier design.
