What do you mean by "work with audio"? Do you mean people who use
audio in their work? i.e.musicians,producers etc?Or do you mean people
that repair equipment, like a service engineer? If its the latter then
fair enough. The guy who does my servicing can't tell the difference
between a radiogram and a high end set-up! If its the former then I
can tell you that I have done MANY comparative audio demonstrations of
cd players,amplifiers and the rest to PROFFESSIONAL musicians (most
you will have heard of!) and they appreciate the differences that are
there to hear.Of course recording quality is paramount (silk purse/
sows ear). I suppose its all about experiences, but if you can't tell
the difference in sound between a Quad 34/306 and a Naim nait3....

So which of those colours the sound enough to be noticable?
