If you want really wide soundstage, the best I have tried is the sony ex600, they are a bit over your budget but have been the closest IEM with a soundstage of a pair of cans. I have not tried the IE8s, but reviews have said that it is still king for soundstaging.
Looking to trade my HD25s for a HE-300.
The HD25s are in excellent condition, unfortunately my glasses started to chip the pleather pads, part of the extra $ will be added for a new set. Also interested in a pair of orto EQ-5 or 7.
PM if interested and we can negotiate the extra money from my end.
You need to get the L7 adaptor for it...I currently have my e7 powering a tube amp, I do not have the L7 yet (found this out 3 days ago) but running the e7 volume to max does not produce any distortion.
I am not too sure on your optimism there lulzsec, they have never restocked any of their boxing day sale items in the past until after boxing week. That being said, there should still be stock in the stores on boxing day for those who are interested.
