Hello joining late to the convo and I have a different type of question. Currently I stream my itunes lib over my network to the DAC over the ethernet line. I was considering hooking my external hard drive directly into the DAC via USB. My question is would I hear an improvement in overall sound? Opinions please! I love this DAC I had a Sim Audio 100D, this for my system and ears opened things up and bit and the music sounds more controlled with imaging and depth.
