[Shanling]

@Shanling After almost 4 years of daily use, I finally dropped my M8 in a way that damaged it.

It still functions curiously, but the music quality is audibly reduced and I can hear rattling inside which I assume is either a transistor, resistor, or some other electrical component that came loose.

Since shipping back to China for repair is out of the question for me, does anybody know how to properly remove the back-plate so I can attempt to re-solder the component in its place?

If it is something more serious than that I will be sending out funeral invites.

Edit: I found out what broke. It doesn't charge when I plug it in. I guess if something had to break I'm glad it was that. Sure hope it's easy to fix though..

M8 opens similarly to Android phone. Use a suction cup on the back panel, ideally if you have a heat plate. It's held with a little bit of glue and plastic prongs.
Battery is glued to the back panel, with cable leading to main board, so be careful when removing the back plate to not pull out the cable.

Pls fix tidal mqa

@Shanling -

Why can I not RE-install Google Play (and with it UAPP) on my M8? The DAP crashed, again, last night and suddenly, again, there was almost no volume (FW 1.73). So once again (for maybe the 15th time?) I had to perform a hard reset and reinstall and reconfigure everything. I followed the basic flow: "Open APK pure, search Google Play Store, download, log in, uninstall APK pure." But APK Pure is not working. I find the apps I want, hit install, but nothing happens. Same after I updated to FW 1.75.

As your music app STILL cannot alphabetize my large library, and is still not gapless, I find I really need another music app. But cannot install one.

I must say, I love the sound of the M8 but the FW, software and hardware are all problematic. I do not intend to ever purchase another product from Shanling.

That's bug in APKPUre app:

According to info from our software team, the app works in bit-perfect mode with the built-in DAC or USB output. There is no additional processing for the "special tuning" you mention.

This is an automated test using RMAA and Motu M4 Line In (+18dBU). The measurements were made by playing a test sound file through different players in High gain volume 100 and PO mode without connecting headphones (I can continue with headphones, heavy load).
In the last column is the line output mode.
This equipment is not accurate and the results should only be considered relative to each other.
I could not see a significant difference between UAPP and Shanling Music app, but the difference between Addict player is clearly visible. In comparison,, Hiby Music behaves like complete trash.

Spoiler: Measurements

Offtopic:
Today I’m going to replace the buffer driver at the service center, since in my opinion the ADA4610-2 has significant distortion after 10 kHz (maybe a warm tube harmonic, but I want to increase the fidelity). If successful, I will have a report.
Upd: (successful)


Upd2:
important note!
You can see the high frequency roll-off in the frequency response. Indeed, at 16 kHz the decay will be about 1 dB. This is a feature of the operation of the digital filter of the AK4499 chip on PCM 44 kHz. The only filter without the start of a significant rolloff at 16 kHz, as I can see, is "Short delay Sharp rolloff" (see also datasheet of AK4499)

Well, I tried, and I'm disappointed to report that the M8 does not support 48kHz DSD rates.

Can you send us one file to test?

https://wechdomi.org/english/index.html

upsampling DSD1024(48kHz*1024) files.

Maybe test DSD1024 with M9 PLUS as well?

Then we'll also test DSD512 with M8 (and other models) by running this converter for FREE

https://pcmdsd.com/Software/PCM-DSD_Converter_en.html

The WAV files are converted to DSDx44.1 or DSDx48 depending on sampling rates of WAV files.

Or simply give either trial version a try instead, even (much) older hardware turned out to work just fine

It meant I could use my Mac Pro 2013 model running Win 10 to play this 48X512 poly-sinc-xtr produced file through my T+A DAC 8 DSD, where the Mac pro can handle a max of DSD128 with real time up-sampling.

HQPlayer's trial allows you to use the software for 30 minutes at a time for 30 days.

We do have the right hardware here to support DSD at multiples of 48k

https://en.file.shanling.com/images/c202fae334c9db2f40808ec4d5292a05729.jpg

Two Japanese KDS active crystal oscillators and an improved Shanling's algorithm provide a better accuracy and an enhanced performance when decoding PCM or DSD data, up to 32bit/768kHz and DSD512.

Most importantly, USB driver could be handled quickly and it's already available since 2018

I am pretty disappointed with this response. I was able to get the latest Theyscon ASIO drivers that support 48k DSD from a Chinese vendor (Topping) in less than one day. The Topping has an XMOS usb interface, which is the same as in the iFi. I've also given the documentation from of Theyscon that says this rate is supported by their drivers. Aren't they the providers of your ASIO windows drivers? Are they not telling me the truth?

I am simply asking that you please provide me the updated Theyscon driver (or work with Theyscon, your supplier to get the latest). You advertise on your web page that my device supports: "USB Input: up to PCM768kHz & DSD512 (24.6/22.6MHz)" so help me to get the support that I need to make your product work as advertised. Please help out your customers who want this feature!

Why would you, if you yourself chose a device with an AK4499 chip?

• DSD64, DSD128, DSD256, DSD512 Input Support

The AK4499 supports DSD data stream rates of DSD64, DSD128, DSD256 and DSD512 modes. Thedata sampling speed is selected by DSDSEL[1:0] bits

The AK4499 detects DSD mode if the number of clock pulse in 1/fs is in a range shown in Table 41 and PCM (or EXDF) mode isdetected if not.

Any experience here with Hifiman HE1000V2?

I had that pairing, it's an average pairing.
Imo. He1000v2 needed more power.

So helpful! What DAPs might do v2 justice? Looking to keep neutral sound signature and nurture the warmth and wide soundstage.

My guess would be fiio M17 or equivalent.
More voltage / current as possible.

Never having owned a DAP here’s a generic and somewhat naive question- how long is the typical DAP lifecycle? How long before it typically breaks and is out of warranty or is obsolete?

My M8 worked for 2 years, worked without complaints, now it has a new owner, he just replaced the battery and the M8 works just as well, at least I haven’t heard any complaints about the work from him.
I bought a battery for the M8, since over two years the battery degraded a little and began to hold a charge less, I bought the battery for $30 + shipping $20.

I'm the second owner of a Sony WM-1Z from 2018. Only battery was replaced before I got it. It works great. You get a good device, take care of it and the battery, they can last a very long time. As far as Android DAPs go, people worry about the firmware becoming obsolete with apps. Should not be an issue. For example, Apple Music works fully with devices running Android 6 and above. Besides that, Android devices don't just stop working with apps once the system is no longer functioning with updated apps. The last working version on your Android device will continue to work as it did. The worse case scenario is you don't get new additions to software that occur with newer versions, but you will maintain the abilities of the last version you are able to use
