To add to what
@jon parker said about the Ace:
They are slightly bigger than the original EDP (obviously with more drivers) and touch harder to drive but not too much. To my eyes they do not look as good as the original EDP but to me that is where the advantage ends for the original, the EDP Ace are special.
The nozzles are shorter than the EDP but get your double flange tips ready. I am ordering triple flange tips to give me better insertion depth (that is as clean as I could express it).
I put them in last night for sleeping, put my sleeping tracks on, and fell asleep...a half an hour or so, I was woken up by sub-bass like I have not felt from any other other earphones (bone conduction like no other, not that I have tried them all). It may be the bone conduction but the note weight has heft.
Naturally, I stayed awake and listened to the track and then I hear this astonishing treble extension, it was just so rich. Pianos notes sound so natural but also the decay on the are like sitting by the piano, this is not reverberation, the note does not repeat it just has a natural tail off. I was using nothing more than the Fiio BTR5.
I honestly do not think Bob was aware that these would sound so good when he was pricing these earphones.
As Jon said, do not cancel your order just hang on in there, even if you disagree with us, you would be making that decision after you have heard them for yourself.
