I did get in the burson discrete opamps, only thing is the casing those opamps are a lot bigger.

Burson discrete opamps wooow i was realy shocked about the difference i now hear.

Loads of more air around the speakers lots of detail never heared came out of the opa2604

Depth is amazing dito weightness i now hear tiny details far behind the speaker set.

 As if you listen to a 750-1000 euro price tag DAC.
