Contents of this original post:
This one is CEE TEE's pair. It's bone stock.

Super neutral, and maybe a bit hot at 3-4KHz, but I couldn't hear it on CEE TEE's amazing Moth prototype amp. Seriously, I loved that combo! It made the HD600 just ever so slightly less fast and euphonic than some Stax. That's an insane feat to achieve. Resolution is almost up there with HD800, and the only thing it was missing was the soundstage of the HD800 to me. Absolutely awesome little thing!

Channel matching is impeccable, and only offset a bit due to my poor positioning skills at low bass and >8KHz. I'd say... it's practically perfect by any means.

CSD shows extreme speed even down to 400Hz on my rig for both channels. Notice the extra decay is mostly due to enclosure/ear pads. In actual practice, I heard this headphone as being much faster than it is generally described. If it's a bit soft/warm/veiled, I think that's more due to rolled FR >8KHz and slight bass bump rather than to any resonance or decay. This is about as clean as anything can get IMO. Certainly much cleaner than some Stax (trust me, I still have measurements of the Stax SR-X Mk.3!), and some (if not most) planar magnetics. LCD-2 and Code-X actually don't measure this well on my rig.  :-0

Side note: I created a new thread because I bought a HD600 as well. Will measure it and compare to this pair once it arrives. And then I may do some simple mods, but... honestly? If there is such a headphone that I don't mod at all, then this is it.

Yeah, I really want a pair after listening to one. It's the most natural sounding headphone I've heard.

Yeah... I'm honestly not sure what the differences are between my rig and others that cause the other rigs to not show the amazingly fast speed of these drivers, but I think they are quite fast and clean, and that contributes to their resolution and detail retrieval capability.

If not for the weird ridge around 3-5KHz, these would be practically perfect IMO.

Don, coming from Yamahas I could definitely see the HD600/650 as sounding... thin.

Yeah... CSD is certainly a bit on the thin side on this HD600 that I measured. Will see how the pair that's coming will fare.

I have some ideas for small tweaks that may take away the upper mid peak.

I sold mine a little more than a year ago and after a few "upgrades", I could have definitely just lived with all the good stuff it does and its few shortcomings. After hearing this headphone out of some crazy rigs, it's clear that it scales amazingly well IMO.

While I do feel the slightly hot lower-treble is audible (extra vocal forwardness or bite) it's not objectionable to my ears. Never felt the need to mod that away.
