Thanks for the recommendations, @zolkis! I am tempted to get the Stax earpads, but the price tag is way too steep for me to justify them at the moment. For the other pads you linked, do they all require the sewing to be broken to access the inner foam? Also, after trimming or replacing the...

@zolkis, are there any stock pads you would recommend for the TH900 that come anywhere close to the modded pads you enjoy? I have modded two TH900 pads now and have grown tired of the unpleasant appearance of the crumpled protein leather and the lack of durability (the protein leather flakes off...

Great work experimenting, @zolkis . Your write-ups are helpful as usual!

I plan to attend as well. I don't plan on bringing any gear this time.

Sure, I can try. It has previously taken me an awfully long time to cut the foam to the exact dimensions. I'm considering using a heated blade or a fancy heated string foam cutter this time to see if that makes this easier.

I have owned and listened to several HiFiMAN headphones over the past few years (HE400, HE400i, HE560, HE-6, Edition X, HE1000), and they have all sounded terrific to me. Naturally, I am excited about HiFiMAN's latest flagship offering, and would very much like to own one.

I recently changed my felt rings out for the original foam dampers, turned to the bassiest position recommended by Whitgir. I think that it's tightened up the sound a little. I'm getting slightly deeper bass, and more punch/dynamics overall. This is a good thing to my ears. My protein pads have...

  If I'm not wrong, R2R, Ladder, and Multibit, all refer to a Resistor Ladder DAC.

  You can actually create angled carbon pads if the shallow pads bother you. That's what I did (~24mm back height tapered down to the recommended 7-8mm on the front, and it worked well for me, without any noticeable effect on the sound. Note that I actually stacked a "booster" piece of foam...

  Of course. Whatever works best for you!

  Here's a video that shows you how to remove the pads:   https://www.youtube.com/watch?v=BjOr2kcQJDk   For the carbon pads, the leather will be loose. Grab the loose leather, instead of the foam stuffing when you are twisting the pads in and out of the slots.

  The pad mod makes the biggest difference. Did he include the carbon foam pads as well? If he did, put those on and give'em a shot :)

  I helped him mod those. I hope you enjoy them :)

  Looking good! What made you remove the felt from inside the cups?

Green.

  And that's why this is one of the tracks I use to test bass impact :) Glad you like it! Thanks for the feedback too--looks like there's something going on in my cans...

  Nice job! I might try swapping back to the foam rings soon for a little change in flavor.   Quick question: do you hear any ringing in your TH900s when you play extremely bassy music at moderate-loud volumes? I'm getting some ringing in mine, and I'm wondering if it's a driver  or enclosure...

Also, I finally got my DSP update! I'm going to have to do more listening, but I am quite satisfied right now. My first impression is that I'm getting more focus, and the soundstage is less in-my-face now, which I like. I'm also getting more treble sparkle, albeit a little artificial-sounding...

Anyone ever experience a transient problem where DAC-19 only sends (pretty high) output only to the right channel? I'm noticing this sometimes when I power cycle my DAC-19, and once even without a power cycle, but the problem goes away after a few minutes.

  Thanks for the tip. I've added Audio-GD's Teamviewer ID to my contacts list. Let's see if this works tomorrow morning.

  Are you using it in reverse, i.e. to connect one source (DAC) to two outputs (speakers and headphone amp)? If so, how do you have it set up?

  Turns out they just straight up missed my appointment. Wonderful. Time to try this again.

  Right. I realized this and e-mailed Audio GD 5 minutes after my appointment start time. I received no response for the next 30 minutes. Is e-mail the only way to send Audio-GD the password at the appointment time?

  Ah, right. That's very probably true. @WillBright from Massdrop might be able to comment on this.
