NAD M 51 Masters Series DAC, Preamp w/Beeswax superfuse

This is the very nice NAD M51 upgraded with AudioMagic Beeswax Premier Super Fuse (1 amp/slow blow/short - equal to OEM) Many accolades have been written for this unit. The AudioMagic beeswax fuse makes background quieter (lower noise floor) and as a result the tonality improves - especially leading edge transients - more accurate/natural sounding timbres. The original fuse is included also. This was purchased app. 1 year ago and was used in a pet and smoke free environment. shipped with owners manual (on disc, like original) quick start guide (pamphlet) 2 power cords, remote, and original fuse. color-black
Output impedance for amplifier matching (when used as a preamp) are: RCA-47 ohm, XLR (balanced)-110 ohm
