Just got the Ortofon EQ-8 in this morning after offing some stuff at HF. It was recommended to me by HF's ShotgunShane. I've spent a good amount of time listening to it and...
Good Googaly Moogaly man. This phone is god damned astonishing and probably the best phone I've heard for rock music full stop, full sized or otherwise. It strikes me as feeling like a hybrid of Final Audio's FIBASS and Ultimate Ears' UERM. It possesses the former's confrontational, in your face and practically raw presentation and the latter's linearity and wide, open sense of space. It feels like music is just laid completely bare on the EQ-8, and the overall sensation is like immersing your entire head in a sphere of music. Seriously, the sense of space and immersion is crazy for a single driver. It feels like it fills every inch of your skull and then some. It's up close and personal like nothing I've heard. If emotion is your bag, then this is your phone.
The only caveat I've experienced thus far is that it can lean towards edginess in the upper mids, but it's manageable and far from a dealbreaker in my book. By the same token, it's this same quality that translates into some seriously sizzling guitar leads, sparkling rides and cymbals, soaring vocals, and mesmerizing synth lines. I'm very impressed by the bass articulation as well. It's very articulate, linear, seriously punchy and textured even if it doesn't quite plumb the lowest depths. But damn son, those mids. Fuck.
Anywho, HF's shigzeo put a lot more time into articulating this phone's strengths than I did:

I don't quite find it as persnickety in drivability as he did though, (I'm just using my iPhone 6) then again, I don't currently have a low ohm portable amp on me. There's still a unit at Musica Acoustics for $260-ish if anyone's interested. I loved the Stax acquisition but damn man, I dunno, this phone man, this phone.
