This RE-400 thingie has such an incredible soundstage. 3D is probably the best way to describe it. Imaging is spectacular - you'll never wonder what instrument is playing where; yet at the same time, they're all integrated so beautiful so as to not sound analytical. It's not overly creamy, not yet overly dry.
Right now, if I don't EQ it, it doesn't have as much treble as I would like, unfortunately, and it's a bit warmer than my ideal. With EQ, if you were to tell me these cost $100 I'd seriously laugh; and if you were to tell me they were $300, I'd call it a great value, considering the ER4S costs about just as much, and I'm liking my EQ'd RE-400 much more! With the current EQ setting, it surpasses my ER4S in terms of sheer musicality and immersion so easily it's not even funny; although, it's been mentioned quite often that the ER4S scales up very well with better gear. Unfortunately, I haven't the resources to do that yet. Cymbals just sooo natural and right, compared to that of the more metallic sounding ER4S and GR07.
I'm going to let these play for at least 48 more hours before I say anything else. So far, they've only been in my ears for 2 hours. I'm really hoping these will get brighter with burn-in.
Ohhh... this is delicious...
