Review and Measurements of E1DA 9038S BAL Portable DAC & Amp

Sorry- didnt ignore this- was just hoping it would arrive shortly after but as I type my national postal service still havent received. I am hoping customs dont go prying. Hope yours has arrived and is delivering smiles. I am long past expecting wonders from these things- the existence of all such things is wonderful enough. I am fully expecting it to sound no different to the Sonata HD Pro and Meizu Pro I have, but might be able to power more challenging cans better whilst sat at my kitchen table (now office desk) away from my main rig.
These are the words of a wise man :). Jokes apart, my device is still in customs.
No need to say sorry, sir. I don't usually expect responses, since everyone is busy with multiple things to do. I liked your practical answer.

Received mine today. Sensitive IEMs up to 250 ohm Beyers driven comfortably. Good work @IVX
 
Jimbob54, yeah, you look experienced headfier because you did reflash your 9038D for a minute. As you can see in our discord channel, I all day explain to my users how to open zip file or why light clicks-noise during On/Off DAC isn't dangerous for his speakers ;) People seems really never had a deal with hifi..

Ha! I know where you are coming from. In an ideal world everything would just work without any issues (dangerous or not) but even huge companies struggle with such things, especially software.

Looking forward to seeing how the app works

My two units of #9038D were delivered yesterday. Picked up the package from my mailbox this evening. Delivered in just 12 days from ordering!

Tested both units using USB from MS Win 10 PC feeding 16/44.1 FLAC files and with Final A8000 IEM with 3.5mm to 4.4mm adapter. The clarity and resolution across the whole audio band are just exceptional. I have the MS Win 10 driver volume set to 50% and the MS Groove music player application volume set to between 50% and 60% depending on music. So there's tons of power if I should ever need it. I am tempted to crank up the volume to -0.5 dBFS just to bathe in the max SINAD and SNR :D

As I type this, I am listening to very fine jazz vocals from around the world which the #9038D presents such detail and lack of coloration that the realism is hypnotic. Of course, the high detail resolution of the A8000 IEM or similar transducer is needed to experience this. A superb device for a very reasonable price. Thanks to Amir's review highlighting the stellar performance of the original E1DA #9038S, which the current #9038S G3 and #9038D improve upon. The build quality of the E1DA dacs is reflected in the firm metal and the fine exterior styling and finish.

Included in the package was a fine artsy E1DA PCB with circuit components facsimile in copper, that is perforated for use as a keychain fob perhaps. Thanks @IVX for an unusual gift which I will twirl ostentatiously while talking with friends, whenever I get the chance! Now I await the release of PD v2.1, which StaticV3 said is going to be also usable as a DAC to feed a headphone amp.
 
JustAnandaDourEyedDude, I don't know what I should say when every week somebody asking me to send them for free my DACs "for a positive review". You bought 2pcs and posted a wonderful review ;)
BTW, the PCB you've got is the real one, I asked my Chinese wife Sunny do not throw out old PCBs(9038SG2) but send to our users like a little surprise. Actually, PCB is gold-plated and looks too neat to be in a waste-container. Sunny was surprised by that idea and asked me - but why, why?? I have no idea how to explain and said - just do it, please.

That is awesome! I will treasure it all the more. Yes, I thought that was not quite the right color for copper. Surprise, it's gold plating! It is a work of art. I am going to wrap it in some protective transparent plastic before I show it off in public.

I posted a review just out of the pleasure I am experiencing. I am listening to a singer named Mirka Klos at the moment. Don't understand more than a couple of words but I love her CD which I bought. I should go to sleep, because tomorrow I have to work, but I am going to keep listening to music with the #9038D for a while :)

9038D opens up my Ety ER2SE nicely- other dongles have struggled a little. Between the G3 and the D I need never touch another DAP as long as I live. Hurrah!
 
Does E1DA like other many similar small-form DAC/AMP suffer from the EM interference problem (noise when sms or phone call from mobile network)?

Possibly. Depends on what frequencies and networks in your region. Fine in the UK until you get very weak /no signal
 
Anybody use 9038S with iPhone and MacBook? I know they're not officially supported but does it work after all? Thanks

MacBook is no problem in any case. Not tried iPhone.
 
9038SG3 works perfectly with my iPhones 6 and 11. IPhone hardware volume is supported only by G3. G2 worked too, but only with software volume. You need a lightning to USB C decoding cable (by Penon Audio or Meenova) or the Apple camera adapter and a normal USB A to C cable.
Have no Apple notebook so can't say anything about that.
Please be aware that the 9038D does not support iPhones as it draws too much current. Was quite a bummer for me.

Hi again, what do you mean by hardware volume? I don't see any physical button on G3? I assume it's important as SW volume destroys bit-perfect, am I right? Thank you in advance!

Adjusting the volume on the dac chip rather than the level of the signal you feed it. Any adjustment of volume makes it less than bit perfect, just use whichever is easiest.

@somy It's the iPhone's hardware volume I meant. G3 supports it, that is you can change volume with the phone's hardware buttons and the iOS software slider. G2 always had 100% volume on the iPhone unless you used a player that has its own volume moderation like Neutron. The D version supports the iPhone's hardware volume, too. However, it draws so much current that you have to use an additional power bank. Therefore for on the go use not practical at all.

You need a player that can access the hardware volume on the chip- so either something PC based or an app on Android like USB Audio Player Pro- thats what I use and there is a "hardware volume" button in the UAPP interface where you can adjust the volume sliders- its doing it directly on the 9038 .
