The LME49860 attenuator /buffer and TDA7294 is not quite as definitive as my A/V receiver, as a matter of fact, sort of thin. I do need to replace some signal path electrolytic capacitors with polypropylene maybe increase the input coupler to 1uf from .6uf.
I hear the TDA7294 sounds better with a 44uf bootstrap cap, with no engineering manual, I sort of feel hesitant to try it.
