Yeah, I'm fairly confident mine is Rev.2. At stock, it doesn't sound that bassy. Kinda neutral... but with a ton of body and thickness. It was frankly a bit too full, so that's why I started modding.

I think I got somewhere... but the problem is that my pair has a channel imbalance, so I ended up modding each side differently to compensate for the slight channel imbalance. And I'm not sure how I can proceed with writing more instructions since those may just be specific to my pair after all... but... I guess I can try to give some pointers?

Imbalance is the absolute worst. OCD trigger !

I measured very carefully using my phone and one other generic microphone I ripped off of an old unused recording rig (the cheap kind), and got the imbalance down to 0.5dB...

I almost thought I'd have to resort to soldering a resistor in series, but I'm glad that didn't happen. Now both channels are happy, and I'm actually getting a consistently bigger soundstage than the HE-560, likely as an effect of the channel matching... but I'm not sure. Will have to see someone else's measurements of this pair since I'm not sure I set everything up right.

But there's no doubt IMO that a modded LCD-2 is my new holy grail. HE-560 was good, but this is better. <- sorry, Jerg. :p

I'm still trying a few things with the HE-560 to see if I can get it to this level, but... it's becoming painfully clear that the driver may be the limiting factor after all.

I mean I don't doubt your impressions are your impressions, but you modded your HE560s using an entirely different thought process and goal from mine so it's hardly comparable.

Haha. I know. I was joking. Sorry, that might have come off wrong.

I'm still looking at the HE-560, and will probably send it back to Marv in a few days. And then you'll know what I did. I'm sure what I did should give a different frequency response... though whether that's for the better or not is really up to the beholder.

Right now, I'm trying to make it so that good technicality is obtained as well.

Might want to get a used pre-fazor LCD3.  The LCD3 driver seems way more capable than the LCD2 driver (that is if you get a good one-- if Audeze is still having that problem.)

The LCD3 diaphragm is thinner, and the magnetic array is a true dual sided, whereas the LCD2's is alternated.  LCD3 just doesn't punch as hard though.

I personally never cared for the LCD2, but the LCD3 I had was nice.

Yeah... I'd think the LCD-3 would be easier to deal with. Provided you get a pair that's got good drivers. It sounds to me like the LCD-3 is even more prone to driver issues... being that it's using a thinner diaphragm.

At this point, I've learned quite a bit about planar, and from what I can see, it's generally like this:
Thicker diaphragm = more thumpy, bass more substantial, kinda more veiled depending on magnets, and not able to pull planktons out too well, though better than most dynamic.
Thinner diaphragm = less thumpy, more snappy, audibly faster, less veiled, able to pull more planktons, approach e-stat performance

Legend has it there existed a LCD-3 that could match the Stax SR-007, and maybe even exceed it. But that thing lasted for only 24 hours, and I'd guess... due to diaphragm strain and tension.
