Trickle down theory is a wonderful thing. In consumer electronics, it means that after the R&D Department spends big dollars on creating reference products, all the products down the line will benefit from that research. Enter the NAD 390DD, a trickle down product benefiting from all the research that went into the M2 master series digital amplifier. There is no analogue stage in this amp, everything is digital from input through to the speaker terminals.

This unique modular design means you can configure the amplifier to suit your needs, so if you want to add an analogue input for your turntable you can add the appropriate card. There is also an HDMI input board, for stereo decoding and video pass through with three HDMI inputs and one out.

All of this is for nowt if the amp doesn't sound good though, so its good thing this amp delivers the sonic goods. Come on in to try it out, you'll be impressed by its transparency and dynamics.
