What an idiotic comment!
You asked for advice; I gave it (with a background in
audio, audio-gear design, and familiarity with the gear
you were asking about...). Next time, indicate what
answers you want to hear, so that when we take the trouble
to answer your question, we will not waste our time
and yours giving you answers that you don't want to
hear...;-)
