Default Super I/v active IV v1.1 revised +XLR +gain +low pass filter

Super I/v revised
-24khz low pass filter(Qfactor=2.4) decoupling caps and XLR of course
-the design allready been tested very good sound high wattage resistors -----where needed reduce noise and increase quality
-no more pop ups
-at the @cross point@ can be set low when no audio on DAC using simple NPN with collector to ground

Recommend tweaks and improvements
dont increase gain more than 5 times ,better having the first feedback resistor higher

What is super about this? It looks virtually identical to datasheet bog standard, except for the very strangely chosen & I would say ill-advised (un-spec'd)electrolytic accross the inputs.
