The first thing I noticed about the change is cleanliness of the audio output and volume. Much cleaner and balanced volume. I tried a few more tracks, noticed a slightly wider sound stage on my R70x (almost non-existent before) and very detailed bass which I have never noticed before. Definitely noticed instruments I have never noticed before far in the background. Bass is less pronounce as compared to all setups above, less punchy but more detailed. Mid and high are well controlled as well, sounds a little warmer/mellower than before. Separation is a not a night and day difference than before but noticeably better. This setup is something you can listen to the whole day without feeling fatigued.
