With 40 presets available to program your favourite radio stations, the C 427 makes listening to the radio both smooth and enjoyable. With great reception and ease of use, the C 427 heightens all the things that make radio great, resulting in a gratifying experience.
As I use no instruments to measure audio equipment, my comments are strictly subjective, First, I'm a huge fan of NAD equipment deeming it to be the equal of the once great Dynaco equipment. NAD has been dubbed the poor man's Marantz or Macintosh, and I agree.
This C-427 unit replaces my NAD 4155 tuner. To me, on good stations, the sound quality between the two tuners is identical (superb). The C-427 is more sensitive in picking up stations. It is always in Standby mode when turned off, so unless you unplug the unit one's preset stations remain in memory. In the 4155 tuner, there is no standby feature, so when you turn it off all power is removed. On it preset stations are memorized via a capacitor that will slowly lose its charge. If not used regularly, the 4155 tuner presets will disappear and must be set again. The C-427 utterly avoids that problem.
One negative feature on the C-427 is the shiny legs supporting it. They are out of character with the otherwise beautiful simplicity of design. All NAD equipment is aesthetically understated--to me a most desirable characteristic. So gegaw lovers (with many switches and sound controls) should probably look elsewhere.
Bottom line: A very fine tuner well worth every penny of your investment.
