TANCHJIM Space Portable Headphone Adapter Review

[bumblebee657]

1. Download the .zip

2. Unzip the .zip

3. Double-click the unzipped .exe

4. Done

No, that's really not how easy it is. You have to unzip, then install several drivers and then do the update. I have had big issues updating mine and in the end I found out it doesn't work from a (windows) network drive, but has to be done from a local harddisk. So that really isn't user friendly. Their software including the Android app is a big piece of crap.

I would not get it again.

What I wrote is the step-by-step instruction to installing the ASIO driver.

How about updating the firmware?

I just bought this device. And unfortunately there is a problem with the test of the default audio format in Windows 10 64-bit (Settings -> System -> Sound -> Device Properties -> Additional Device Properties -> Advanced -> Default Format -> Test).

With any of the 24 available audio formats (16/24/32 bit with 44.1 to 384 kHz), the test sound (chime) on each channel does not start at the beginning. The first few milliseconds are missing. It is clearly audible.(...)

+- the same behavior with Moondrop Dawn Pro(CT7601+CS43131), it cuts the first part of anything above 96000Hz.
16/24/32 bit up to 96000Hz works, anything above does not.

Just for reference, i do not have this issue on my Linux Box.

The highest i have is 192kHz and it plays like every other file.



(Pipewire, the processing engine above the sound system on Linux, does everything 32bit float internally, that is why it shows S32LE but the original song is, as you see in the line below, 24bit. But i noticed no difference between 16, 24 and 32bit).

I created a very short test file and if i play it, it instantly plays, without any delay or whatever. There is no cut of the first few ms.

So if that helps, it is an Windows related issue and probably able to be solved in Software.

But its no surprise that Tanchjim and Moondrop Devices show similar behaviour as this is basically the same company. Tanchjim seems to be a subbrand of Moondrop (there is no official information about that, but an employee of the Japanese subsidiary told me, that Moondrop, Tanchjim and CHIKYU-SEKAI are all the same company).

So the Tanchjim Space and the DAWN PRO are probably the same device.

Oh, by the way. I can get full 4Vrms out of it without any clipping or distortion. I noticed in the initial Measurement, that there appears clipping. The same happend to someone testing the MIAD01. He said he can not go to 4Vrms without clipping/heavy distortion.

I noticed the CS43131 does impedance detection when you plug something into it and you can not change impedance afterwards, otherwise it starts to behave very strangely (frequency response is no longer flat and stuff like that). Maybe that caused it.

But i can say for the Tanchjim Space and the Moondrop Dawn Pro, i can go to 100/100 High Gain, full 4Vrms, without any clipping and an perfectly clean sine wave, both 3.5mm and 4.4mm

Could also have been fixed by a firmware update. I bought one a couple weeks ago and it had different firmware than the launch version (it saved volume settings when unplugged, which launch firmware did not do)

I have massive noise, as soon as my smartphone is in online mode (LTE).
Everything is ok in WLAN mode. Can anybody confirm this?

Never used on LTE but never heard noise on this full stop .

LTE interference is a common issue with dongle DACs.

It's a very distinct, dial-up-like interference noise, very different from the usual hiss or mains hum noise.

Oh, I know what it sounds like . I also know from past experience how much phone signals can impact a particular dongle depends both on its design and the frequency of the signal that interferes . I had one that was fine when I was on 4g but when phone stepped down to older bands it made the noises.

But ideally of course we would want them immune from intererence from any bands .especially given their portable use case .

 

[Vamp898]

I do not have this issue with the DAC inside the MIAD01, haven't checked with the DAWN PRO yet (use it always on the PC), but it might be worth checking it, one moment

 

[Vamp898]

So i tested the following.

I started recording when in Airplane mode, left airplane mode, opened firefox and did a speed test. This is the result of an 30 second recoding (using the DAWN PRO)

The measurement is limited by my DI but as you see, its nothing but noise floor around <=-130db

I sadly have no Tanchjim Space here with me to test, but at least with the DAWN PRO (they are, in theory, the same device), there is no feedback from the anetanna.

I even have Dual SIM. One SIM Card uses LTE and the other one 5G.

 

[Bow_Wazoo]

Disappointing.
I didn't have this problem with the Hidizs s9 or the Fiio KA3...

Worth noting phone band frequencies arent the same worldwide . Maybe it's only sensitive to frequencies in your territory and not @Vamp898

Yes, but not like constant noise but rather frequent tic/click noises. Here's 2 minutes of -20 dBFS ~1 kHz tone with https://fast.com/ test running in Firefox during the second half, on Wifi:

and on 4G LTE:

It also seem to depend on the audio signal level. With -60 dBFS tone the tics/clicks were much less frequent.

There is no problem with any of my phones. Perhaps different cell band behaves differently. Have you tried switching between 4G and 5G if there are any differences?

 

[Bow_Wazoo]

I don't use 5g

It most surely does.
