Ok any comments on the NAD at all
Are you using a stock EE DAC plus? If so, you may want to spend about $300 on some discrete opamps (Dexa or Burson) and some NOS tubes (Mullard, Amperex, etc..). To my ears these "mods" dramatically improved the sound for a rather modest investment. If you've done this and still don't like what you hear by all means look elsewhere.
