Currently been using Apple phone or USB thumb drives for playing music which are limited to a higher quality. I would like to use my FLAC music along with EQ setting adjustments within the Hi-Res player USB that will signal out and into the Harley Davidson USB. Are there Hi-Res players that do this? Is this called USB DAC? Will Onkyo DP-X1A provide what Im looking for? Thank you Hoping to be educated!!!
