Measurements of Soncoz LA-QXD1 Pre-production "Evolution of KTE Board"

[WolfX-700]

Noise spectrum, jitter in ps? Perhaps compare to your budget spdif converter that is also good.

I will do this, after completing the Gustard P26 preamp measurement-believe me, this thing requires a lot of measurement, there is no SOP at all

OK! Gustard P26, exciting!!

Hello everybody! This is my first post. Sorry for my translation of English.
This is a very beautiful engineering product, a great success of the developer. But I was waiting for the SRT6862 and SRT6863 to be swap places for the mute keys on the differential cascade. These are energy-efficient oamp and we measured and heard it. Without XLR connectors but contact pins on the board so that I can use durable professional connectors. And contact pins for volume wires. And I was expecting the old price of $ 100. Case as an option. I could also integrate this board into an amplifier or other professional device.
I am a home audiophile. I am a musician. I value my money and can distinguish the professional series of the ES chip against mobile by name. My name is legion. I am a buyer on Aliexpress.
I am waiting for price $ 100 for bestselling DIY board. Good luck!

Why? It's a minor xmos firmware change if it's not already implemented. The Tone Board didn't magically become more expensive when they added volume control through USB in a new firmware release.

Well, then, maybe he'll add the feature in a future firmware update.

Linearity to -120dB within 0.5dB? We are spoiled here.

Can anyone please link to an explanation of the Linearity metric?

Uhh it is on "sale".

Joke aside, I might buy this!
How is the feel of the buttons on the front? They look a little cheap.

im pulling the trigger as soon as it does go live

This is a simple measurement and the question is what do you want to know.

Jitter or something else?

I have something else to measure today, you can tell me what kind of measurement I want me to take, I can do it later

It is not important actually, but I remember Amirm testing the D10 from Topping as a USB to SPDIF converter in order to see how much of the original signal was "converted" to SPDIF and it went out to be a very good DAC also for that purpose. I mean, probably no one will buy it for that, but knowing that it will do it without degrading or adding jitter to the signal, would be something nice to know

@Ben1987 are LA-QXD1 and SGD1 compatible with 32 kHz sample rate via SPDIF? I see most DAC's do not go below 44.1 kHz sample rate

Mr Wolf, I'm investigating on the hump issue a bit further to see what exactly is going on. Would you please test for -45db and -35db spectrum for some reference?

Is it okay tomorrow? There are a lot of measurements to do on the weekend, and my table has almost exploded.

Sure! Take your time.

 

[Dreyfus]

Any info on the estimated availability, yet?

I was 100% sure of buying the SGD1 when available. Now I'm 9000% sure, in Black.

This!

Hi, I am not very experienced, but unless I am mistaken, there is not comparison SINAD ?

THD+N divided by 6.02 should give us the SINAD, so 116dB/6.02=19.3dB of SINAD.

Based on https://www.audiosciencereview.com/.../best-headphone-usb-c-dongle-phone-png.42758/ (hope this was the latest THD+N chart), the SXD1 is between SMSL S500 XLR and Oppo205.

 

[WolfX-700]

Sure! Take your time.

right when i got my khadas, i see this. i will have this for sure.
hope this is also shipped from europe, so that we europeans avoid customs. or at least it can be shipped through gearbest or banggood using priority direct mail, so no customs for us.
this really looks amazing. this thread is bookmarked.
will the dac need any drivers? (just asking).
thank you for your terrific work

For XMOS last line

I also can not find anything better with this chip for the same price

Those are signed with SMSL vendor id though.

Windows 10, OSX and Linux have a general purpose UAC driver anyways.

oh sorry, this is not the same thread, I am considering the SMSL 10th for purchase
I'm waiting for the same great engineering Soncoz product with a chip AK4490
