They are new car expensive for sure, but I am glad to be able to hear a system built around it every so often. Yeah, cables have always been bashed, I do think there is some definite snake oil going on which is why I avoid spending too much, I get my power cables from Ice Age Audio because they are well priced(around $80-160 each) and the difference is extremely audible on some gear, the Sony UDA-1 completely changed especially in terms of dynamic range, slam, smoothness, and bass impact, it hits like a sledgehammer now(the Elear's bass was a holy crap moment on it especially when running on optical instead of USB). The Schiit Lyr 2 did as well, I went from feeling meh about the Lyr 2 to actually liking it, it wasn't tube rolling that saved that amp for me, it was the power cable. I just have a couple cheap Furman M-8X2's stacked(read you shouldn't stack power conditioners as it usually takes away body from the sound, had the opposite effect in this case, more body and control). Yeah, I find a lot of schiit gear to have a bit of a haze in their upper registers which I find fatiguing. Some SS amps manage to pull off a somewhat tubey sound. Those Fostex T50RP drivers are incredibly inefficient, some of the worse I've come across to drive, but if you want to know horrid to drive, try the AKG Sextett, easily the hardest to drive headphone I've ever owned, inefficient with 600 ohm impedance not a good combination. The Amiron is definitely warmer than neutral, but I do find when well driven the dynamic impact and tactility is impressive.
I wonder what the Milo would do to my DT 480, that headphone has some straight up scary dynamics and mine is 25 ohms, it would reign-in those aluminum drivers in with real authority for sure. It's a bit hard to explain the experience the DT 480 offers, absolutely no grain, a complete void of it, but when you listen to louder volumes on the DT 480 it's like an all out assault of dynamic slam in your eardrums yet you're not fatigued by hash, grain, etc. I expect my ears to protest but they just don't. Instead the dynamics bore into your skull with an intensity I haven't experienced in any other headphone. At lower volumes it's not like this, just super fatigue free, dynamic, and smooth with one unique(albeit flawed) sound.
