this circuit may be what I am looking for BUT I fear all them transistors may produce alot of noise seeing how the amp is connected to the filter outputs

also thought of 10 LM3916's but now were $30+ just for a display (chips only)
my thought was use several uln2803 and maybe an Aleghro A6279EA-T
just rambling ideas
theres got to be a way to build a LED vu meter but at a low cost using modern chip technology.
any input would be helpful
