I know a lot of people who uses these modules as their source to quickly provide some music files to their amplifiers. I am one of them, My main source is a computer fed via a SMSL DAC but i do have one of these modules rigged to a small power supply which I use at my other secondary system to listen to FLAC files. I was just wondering how good are these modules? I mean measurements or how well it does the job compared to a old standard CD player.

here is a photo of the device. (module)

Does the product have a name? Or could you provide a link?

If Amir measured one of these, I'd fully expect it to be among the top 10 worst source devices on his list.

with reference to this thread's title: clearly you aren't reading my posts!

It's probably mega-shit, but if it gets the job done...then why not?
That being said, I wouldn't be surprised if it measured better than a cheap cd player from the 90s.

Sidenote: that is one of the funniest unintentional (?) clickbait titles ever posted on this forum.

I used decommissioned phones. They work perfectly for a very low-cost headset, and you can add a shit-pot full of MP3 or plug into a NAS if you really need space.
As far as functions, there are all sorts of EQ things you can install. Cost "look in the top drawer," You probably have 5 retired phones that will work as good, if not better.

Measurements? Honestly, what doesn't sound good today?

Good luck

Yeah seriously. I'd be surprised if it was subjectively any worse than "perfectly okay". Because that's technically hard to achieve almost. If it isn't absolutely broken (super hum and noise etc.), I'd expect it to be perfectly acceptable especially for low demand applications.

 

[kemmler3D]

I'd guess it would have pretty bad distortion... Not sure if your use case really demands quality though.

You can send one to Amir and see if he will test it
Baring that, you can send one to Danny at GR Research and he will modify it so it will compete with the finest audio processor available

Well, only in your imagination because you spent the money... (Smiley face, can't do emoticons on my bloody phone).

The forum doesn't accept unicode emojis, but got a few basic ones (that I'm totally overusing ):

Don't blame your phone, the middle three dots let you post smileys:


Alternatively you can type out the smileys in ASCII and the forum software will convert them automatically:

There's a bunch of listings for very similar products on AliExpress (well under 10 USD!). Only performance spec I could find was "Signal to noise ratio >= 89 dB" which if true is kinda bad, but subjectively it may sound alright.

Contrary to the suggestion of the thread title, this is extremely far from the stupidest thing ever posted on ASR.

Suitable for a super cheap kitchen radio DIY project. More than that, probably not but a kitchen radio, bedside radio can be nice to have so why not.
Together with a super cheap small class d amp, some small full range speaker drivers, (radio) box and a little tinkering and voila.

A little too peppy led color bar on the display though. Wouldn't surprise me if it flashes once turned on.

Agree with that. Small projects for fun. Building Lego speakers with the kids or a DIY kitchen radio (see post above) could be something. You don't have to aim for good hi-fi or even (low) hi-fi to tinker with a little audio project.
