    What are you driving the modded HE6 SE @loadexfa ? My HE6 SE is slightly modded as well so very curious about this RD mod. Mods improve the HE6 SE a lot.

    I think there is a clarity and airiness in the mid and treble of the higher tiers HFM that the Audeze lack although RD mod LCD-4 can be different.

    This was at the meet at my place, it was a Flux amp that someone brought. I don’t know exactly which one, I believe the owner said it cost $750 which narrows it down but that still leaves a few to choose from (their lineup is kinda confusing in that way):

    It had a TON of power and had an easy time with the 6se so that should narrow it down to the ones with the most power but I think there’s still more than one option like that.

    I figured I should report back to this thread as well. I am now the proud owner of the HE6SE that I listened to a while ago. Thanks to @loadexfa for his generosity and @rhythmdevils for making this.

    That basically says it all. I also have a confession to make: stock pads were a bit too soft and kinda "hot" to me so I swapped the pads for something less hot (more breathable) and ended up with a more comfy seal. FR didn't change much if at all.

    These are very very good. Reminds me a lot of Code-X but kind of "better" in a way. Hard to explain but I would say it's the "effortlessness". I have not had much time for other things recently but I have really tried to find time to listen to these a lot. They are that good!

    P.S.: these are v1 of the headphone.

    TL;DR:
    Probably among the best soundstage I have heard out of any ortho/planar or just flat out any headphones for that matter.
    Treble still a bit tizzy/zippy but I can stand it on tube amp.
    Need plenty of power but punches progressively harder once given enough. Bass is insane.

    I’m glad you’re enjoying them! With the right amp I was really impressed as well, they got closer to the LCD-4 than I expected.

    I spent this morning drilling vent holes into all the various chi-fi ortho iems I reviewed in my big ortho iem review roundup. My goal was to try to vent them more to down tune the drivers and make them less bright with more bass. I had a lot of success! Unfortunately so far the only one I've got so that it sounds perfect with no micropore tape is the PMV PP, which with a new vent hole in the back of the iem now has absolutely perfect FR. One of the best FR of any iem I've heard. Unfortunately they're not the most resolving of the bunch. I got the S12 to sound warmer, and less bright with a much more open sound, better tone and more resolution, but it still needs micropore tape over the front nozzle. I also got the TRN Krin to sound great with 2 holes in the back of the iems and micropore tape over half the front nozzle. (before this wasn't nearly enough).

    So some great results so far! I've learned a lot and hopefully I can figure out how to get the S12 to be neutral with no micropore tape. it's the most resolving of any iem I've heard now, but having to use micropore tape is a hassle.

    If I have success I'll probably offer these mods on my website.

    I'm currently using a Dremel based "drill press" because it fits into my space and I don't have room for a real drill press. It's working well, though the drill bit moves a bit so it's not as clean as I would like.

    I'm just absolutely loving my S12 now. Next step is to make them more open with more vent holes and try to make them neutral with no micropore tape.

    I went too far with the S12! Drilling 3 more holes had previously not increased bass by that much, and I wanted a bit more, so I found some space on the back to drill 3 more, but I must have reached a critical point where the driver got to breath enough that it gave it much more excursion because they're too bassy now, with no micropore tape. Here's a picture. Not the neatest, next one I will try to line the holes up nicer.

    I also have gotten good results with the TRN Krin, which now sounds neutral with great bass, a touch emphasized but great quality.

    And the PMV PP, with just one hole fixes the plastic tone and balances out the FR, with a bit of a bass boost. I might try a smaller hole next time but I think a lot of people will like this tuning.

    I would like to figure out the Good Planar GL12 because it has the strongest magnets, you can pick one up by the other just from the magnetic strength.

    I fixed the treble and midrange with 1 hole in the back (which is already open unless it’s fake openings ala Schitt DACs), and 3 holes in the front but I lost all bass. But the midrange to treble sound great now! Maybe I can fix them we’ll see. :)

    I've got the Shuoer S12 tuned to where I like the FR with no micropore tape over the nozzle they're very neutral and I'm really happy with the sound and excited to be able to offer a great sounding ortho for a really good price. I'll probably sell them with mods and with a better cable. I'll post another update when I get another S12 in and can mod the to look prettier than my prototype and post some pictures.

    Just looking into custom cables and iem cases now... :)
