The Duo phono preamplifier is green at heart with less than half a watt standby power consumption and auto power down feature if the unit isn’t used after a 20 minute period. This in turn gives the unit the same worldwide voltage for compatibility wherever you are in the world.
The Duo seems to exude an air of accomplishment. It’s a solid, lightweight piece of tech that just looks plain good... A rich and rewarding listening experience I just can’t tear myself away from... Few other options out there can match this kind of listening experience, which to put it mildly, is pretty amazing.
