Same thing here. I was considering the 6xx, but the X2's sound close to the HD600's.
So I guess I'll ask: X2's or HD600/6xx vs the HE400i ???
I own a pair of HD650's that I got from a guy who owned a bunch if these. He said the HE-4XX, which seems to be somewhere between HE-400S and 400i, sounds very similar to the 650 but a little harsher in the treble. The X2's are bassbassbass, but still very good quality. Hard to go wrong with any of them, but the HD650/6xx are highly recommended for a good reason. They don't fatigue your ears and are very comfortable to wear for hours.
Hifimans prioritize clarity along spectrum with a tiny bit of emphasis in the highs for extra detail, and with okay soundstage but nice imaging. 600s are mid centric with neutral bass and nice highs, 650/6xx as well but with a tad less treble and a tad more subbass. Both have small soundstages but very nice imaging. X2's are lots of bass (mostly subbass) with recessed mids and treble accentuated a bit, and large soundstage but in my opinion not great imaging. The X2 does not need much in the way of amplification, the others however do to sound their best. They are all open back and so not good for isolation... Basically they are all stay at home cans. Hopefully this helps.

Oh, and the 58x have less bass, way more midbass and crispy treble, and need less of an amp but still do best with one.

I beg to differ. The sennheisers are widely known for their clamping force that bothers many. This should be noted. I have the hd6xx/650 and can tolerate it with a big head but I dislike it still and prefer my akg 7xx
Massdrop is reformulating them a little to add a slight increase of bass, or so I've read.
Sennheiser themselves confirmed it, though how much is unconfirmed. I wouldn't expect it to reach Philips X2 or HD 599 levels of bass, but it should feel more natural.

I would also like to know this. It seems that to get a real upgrade from the Fidelio X2's you gotta go really high end.
