Hello folks, i'm new here. I have been using a chromecast audio for several years plugged into my vintage late 80s harman kardon integrated ampand streaming a 400 gig collection of music from my latop.. I have been wondering if a DAC (have the topping e30 in mind) would improve the sound? Also, what would the logistics of connecting the chromecast audio and the e30 together into my vintage amp entail? Thanks!
