Sorry, missed the replies.
One other issue I had was a massive bump around 76Hz that I never managed tame. I guess they add this hump to try and get over the lack of true bass?
The P3ESR was not as smooth as the Quad S2, I could listen at any volume, any recording and all day with the Quads, the Harbeth started to sound a bit edgy when I played them above low levels.
The room is actually quite a large space, 6m x 5m and pretty high ceilings. Also, wooden floors and no curtains don't help things when it comes to the smooth sound I like.
I whacked in a pair of old Ditton 15s while trying to decide what to put in there, that was a year ago and still got them. Something about them I just love, or maybe they just work with that room.
