Wish I could be more help, but I'm very much an amateur. Good luck with your experiments! :)

I just bought a few bottles of synthetic fabric dye and followed the instructions on the label. There are also instructions on Youtube, here is a video from the brand I used: . The trick is probably going to be the type of plastic and how readily it absorbs the dye. My original intention was...

Here's another pair, this time with the 32 Ohm Lithium Magnesium drivers. I need to spend more time listening to this driver, but I do like it. It seems to be a more mid/high focused driver, which I appreciate. The main problem for me at the moment is that I've been primarily using a tube amp...

I wondered about that. I've only ordered from Aliexpress so far, but the rep. suggested that for custom requests it would be better to order from their site. I haven't tried the 120 Ohm Beryllium drivers yet, but they're on my list so I'll have to grab a pair or two the next time I order parts.

Yes, that's the driver. They do custom impedance on request. You can also order from their website huayunxin.net.

It's been a while since I posted in this thread, but I've been making earbuds again lately and have had some success. This is my favorite so far. A 300 Ohm black LCP/DLC driver from Huayunxin with homemade cable. I dyed the shells and wire and think that everything came out really well...

Sound Rhyme SR8 with NiceHCK Sakura cable and Azla Sednaearfit Vivid tips.

I've been using the Sound Tiger Grazioso since January and I like it quite a lot, but my use is probably a bit different than most. I have a couple of earphones with ~5 ohm impedance and a lot of amps struggle to drive that kind of load. So the Grazioso serves as a kind of buffer in those...

You should see the computer that the amp is plugged in to. :yum: That's the Kaei TAP1-DACs, but it's not actually driving the SR8 directly as 4.5 ohms impedance is a little too low. You can see the Sound Tiger Grazioso on the right edge of that image, which is actually driving the SR8. It's a...

SR8 Just arrived. Have lots of listening to do, but I'm very happy with how the shells turned out. Forgive the poor picture, not the best lighting here on the sofa. :)

I got the version with DAC a couple weeks ago and so far I like it a lot. Enough that I decided to give it a bit of a makeover. I was a bit worried that taking it out of the case would make it vulnerable to RFI, but so far I haven't noticed any problems.

Selling a pair of Softears Cerberus in great condition. Originally purchased used from another Head-fier last November, they haven't seen a lot of use. Included are the earphones, case and metal ID card only. Please let me know if you would like more information or additional pictures. Price...

I've also been listening to the IEX1 a lot recently, but they've been one of my favorites since I got them. I like the Comply tips that they came with and haven't really experimented much with others. It's hard to find an amp that really works well with the IEX1, but very much worth it for me...

CM2000Ti with homemade cable, Korg HA-S amp and Raspberry Pi Zero W streamer. Pretty standard stuff.

I only used regular alkaline AAs briefly, but no I didn't notice any difference when switching to rechargeables. In my case, the majority of my headphones are low impedance, including some that are very low. The IEX1 are only rated 5 ohms and I have read that they dip below that significantly...

I've been using the HA-S for a few months and like it quite a lot. It does have one big limitation; 10 ohm output impedance, but it has a black background and sounds very good with everything I've tried so far. No soldering is required, so it's very easy to assemble. It is a little expensive...

No problem. I hope you enjoy it, it's a great DAC.

The internal transformer voltage can be switched by moving a jumper. It's very easy, you just need a secure screwdriver bit to open up the cover. The set I ordered is no longer available, but this one looks like to be basically the same. Once you get the cover open, the jumper is clearly...

The manual for the TSMR-4 Pro specifically states that the 000 position should not be used. If the Spark comes with a manual, it probably has that statement as well.

The K3 is not a particularly powerful amp, but it should be able to handle a pair of SR80. If you can, try it on a different computer to see if the behavior is the same. If so, the K3 is probably defective and you should return it. If it works on another computer, it's likely a configuration...

You could use a BT receiver with digital out, like the Oriolus 1795D in front of the DAC. There may be others as well, but I don't know any off the top of my head. Of course that's getting a little unwieldy, but people around here have had crazier setups.

There's the Oriolus BD20. It's not cheap, but I'm pretty sure it's a pure DAC although I don't have any experience with it.

The WP900 is pretty energetic in the treble area, but I don't find it to be too harsh. Triode mode does smooth things out a bit. The isolation is not a strong point and it does leak noticeably.

I find it to be a very nice combination, particularly in Triode mode.
