If you haven't done Jerg's excellent Fuzzor Mod yet, I'd recommend starting there. That will remove the ringing in the midrange, which improves clarity and separation quite a bit.
You didn't mention which pads you were using... I'm guessing stock leather or velour. The production FocusPad from the HE560 will probably disappoint you because you will lose some bass. However, the preproduction version, "FocusPad-A" will probably suit your needs quite nicely.
How difficult is it to do the Fuzzor Mod?
I tried to PM Jerg abou the pads if he is selling since from what I read Modular is "MIA". No response from Jerg.
Yes I'm using the stock.
So the next best alternative is the Preproduction A-Pads?
