Tweeter at ear level is generally considered 'correct', but I tend to prefer my ears being at the midway point between the tweeter and cone. This way you get a bit of up/down movement with low/high balance, and that extra spatial imaging tends to help my association with how many highs and lows are in the mix. With the ears 'on' the tweeter, on the Opals at least, it sounds like the mix is coming from below and I don't dig it.
Ermz im curious to see what your setup it like. I gonna go through the pages now and check if you posted a pic
