    ThieAudio Signature Series Tribrid IEMs

    Thieaudio Excalibur and Oracle Quick Sound Impressions In terms of build quality and accessories, Thieaudio’s been pretty consistently lately with their quality control, so let’s just get straight to what matters: the sound. Starting with the Excalibur, the tuning is styled more like a...

    ThieAudio Signature Series Tribrid IEMs

    The difference in Monarch and Clairvoyance vs Oracle and Excalibur really can't be compared to each other. From the start, the tuning difference in Monarch and Clairvoyance in of itself is quite small, whereas in Oracle and Excalibur is quite large. I guess Oracle is similar to Monarch in the...

    Hi, What are some options to add color to clear UV resin? I'm using Egger clear, and Egger UV lacquer. Maybe mixing nail polish into the liquid resin? thanks

    This is the left side before closing the shell (green) and after (purple). Makes me think when i pushed the components in, some passives ended up touching UPDATE went in and realized one of the fullrange drivers got unhooked. Fixed. Blue line is CIEM form and green is UIEM (subbass roll off due...

    6BA build. 1st attempt on the shell and it straight ugly. LR tuning also off...the Green line (right) is the intended tuning and was how it measured out of the shell while initially tuning. Not sure what happened with the purple (left) side...maybe some wires touching inside...

    thanks! I got the diamond tip set so i get what youre saying. Ill give it a shot! And yea, my ears are on the bigger side...i can fit a Z1R in comfortably. Problem is, the bend is almost at a 90 degrees, so i have to drill from two sides i think

    For multi tubes (4 tubes), do you make one big bore down the nozzle, stick with the drivers in, and then seal it by adding more UV resin down rhe bore? Or drill 4 separate holes? im still not good with the dremel, so i cant seem to get many holes without running out room or cracking the shell

    So it doesn't have to be in a sealed shell, but the tubes should all be sealed with the coupler completely? Thanks, I'll give it another try.

    Home-Made IEMs

    I'm using some Taobao 711 coupler, but it measures relatively close to Crin's graphs, so pretty reliable I think. Question, I set up my crossovers, and I can measure each driver separately to confirm that it's the shape I want. But when I try to stick the tubes together in a makeshift "nozzle"...

    Home-Made IEMs

    Hi, so i tried wiring and testing some of my drivers, and my fullrange drivers (ED29689, ED268905, DWFK31785) all came out looking like this. Doesn't look like the data sheets. Just wired directly + to +, - to -. 15mm Tube. My other woofers and tweeters graph correctly. Is there something I'm...

    Will there be any issues of using a lower voltage capacitor (6-10V) in an IEM if the source output is higher (up to 12Vrms)?

    Home-Made IEMs

    Hi, just a quick question. For IEM's, about how much should the voltage be for the capacitors? And for ceramic capacitors, are capacitance loss not an issue for IEM's? Thanks!

    Shanling UP4 & UP2 - Bluetooth 5.0 DAC/AMP with ES9218P, balanced output, supporting LDAC, HWA LHDC, aptX HD, aptX Low Latency, aptX and AAC.

    Will you be releasing IOS app for the UP4? Also, I saw the Android app Equalizer only has 5 bands (63, 250, 1k, 4k, 16kHz). Could you expand it to have more bands, or even parametric eq? Thanks!

    ThieAudio Voyager 14

    The fit is really comfortable. Hence, with all tips I've tried, the isolation has been great. The shell is still half solid resin so that also helps.

    $1000 is a real steal for it! Just the components alone would have been worth it. But it sounds great too so worth it in all sense!

    Tansio Mirai Impressions Thread

    Thanks for the description! U12t definitely seems a little more balanced of a tuning. But good to hear that the zodiac can keep up with the u12t. Does it technicalities (imagin, details, resolution, etc) match the u12t with the custom cable? Was also thinking about the u12t for its technical...

    thanks. Sounds like a smooth tuning rather than super energetic or reference. Can you describe the overall tuning? harmon? Df? V? W? Etc.. So Zodiac is up in the range of brand name totl’s?
