There it is.....just swapped the ear pads, and the sound went with the pads on both the preorder rev. 1 and rev.2 HE560. Turns out HFM changed the tuning with the different material in the pads.
I do like the sound with the new pads though, more sparkle and air in the treble, mids more clarity, bass similar in both. Oppo @hasturtheyellow, noted in the Oppo thread that they use ear pads to tune the sound.....this is a lot like tube rolling imo!
I wonder if HFM realizes the change in ear pads = change in the tuning of the sound......now that puts more light on to what headphone to keep. Going forward what will happen if they decide to change the ear pad design yet again!
