    I just got the LCD2C and am using them with a FiiO Q1. At 70 omhs and 101 dB / mW it should sustain 115 dB with 25.17 mw (1.33 V x 19 mA).

    The Q1 can supply over 75 mW at 150 ohms so it should be have plenty of headroom. Has anyone tried it with a much more powerful amp (say 500 mW at 70 ohms)? I can't imagine it will make a difference since I only listen at 63 dB SPL (calibrated to 75 dB SPL pink noise at -30 dbFS).

    I'm using them with the Audeze Reveal plugin and Loudness correction in Equalizer APO. The Reveal plugin makes them sound like my Shure SE846 and MultEQ XT32 calibrated speakers. I don't like the stock frequency response.

    Just got the Dekoni velour (=Audeze vegan) pads in the mail (that was fast!). Very nicely made. And, as @Hands discovered, they make the 2Cs sound much, much better.

    I might need to get a set for @cskippy to measure. Velour is not the same as alcantara / ultra suede / micro fiber though. It is kind of a shame that they look more like the legacy pads than the new thinner pads. I actually prefer the new shape.

    Even though Dekoni calls them velour, they are most definitely micro fiber...

    I recently scored a well-behaved pair of LCD-2 rev2 and finally understand why fazors were not loved by all... After having owned a number of fazor'd cans (LCD-2F, LCD-X, LCD-XC) this is the first Audeze I've owned with imaging and soundstage on par with the HD6X0 series, and the first Audeze I've ever heard with "air" and treble extension. It does still have the signature 3.5kHz dip, but the FR swing is at least 5db less than any of my previous LCD cans. I've EQ'd the 800Hz drop into a more gradual slope, and they sound pretty fantastic. It's great to hear an Audeze with some technical chops (bass aside) and no cavernous holes in FR. Glad they're coming back to their senses with the LCD2C.

    Also, the Magni 3 does really well with these. Certainly better than I expected.

    Apart from that abyss at around 8KHz that fucks strings without buying them dinner, of course.

    Yeah, anyone who buys an LCD-2 for classical music is probably in for a bad time.

    @cskippy - can you update with the Elite Velour measurements when you have some time away from BF4 and 3D Printing headphone mods?

    Right, forgot about those. I'll update this post once I get home.

    Okay, here are the Dekoni Elite Velour pads vs stock Audeze pads on LCD2C:

    I really liked the sound of these pads on the LCD2C. It fixed most of my frequency response gripes and also doesn't seal quite as well, as you can see by some (minor) sub bass rolloff, but I appreciate the fact that they no longer create a vacuum seal on my ears. Tonally they are much improved, less shout with the 1.5kHz region knocked down a bit, and some nicely added midbass and smoothed out treble. These are good.

    Here is a link to my LCD2C stock pad measurements for comparison:

    @cskippy,

    Can we re-attach the stock pads after we take them off for months? Or do we need to buy another double-sided ring tape?

    @Jerry I had no problems using Vegan pads on my HE-6 and removing them without issue but make sure you press the adhesive against a cotton shirt about 5 times to take some of the stickiness away or you risk tearing the leather when removing the pads. There will still be enough adhesive residue to keep the pads on.

    The LCD2C that I measured was @M3NTAL 's pair and he didn't want to remove the pads as the adhesive rings provided by Dekoni were too strong and seemed like they would rip the pads.

    After seeing @cskippy's measurements I dug out a grungy pair of vegan pads that came as a bonus with my LCD-2 rev2 that I hadn't gotten around to trying yet. Oh hello, upper mids! Why the hell would Audeze discontinue these? They're more comfortable and they sound better.

    Never thought I'd see the day, but I guess I'm an animal rights activist now. When I get home I'm going to fire up the grill, sear a nice steak and write Audeze an angry email about the inhumanities of lambskin pads.
