I owned the NAD 355BEE I sold it, I think I was one of the first buyer of this amp from audio advisor, dark no details dull sound, I have no regrets i sold it, I ended up going up, the only way to hear differences in audio is when you jump for example for an NAD amp and all of the sudden your ears can't live without a class A luxman. Is costly but if you are serious about audio, start with a Rega used amp, Brio 3 or Brio R the new version I owned too, excellent and musical don't buy vintage, too much work repairs and other unexpected things that you will like to be away from....make your first steps in the hobby walking right...
