USB to SPdif converter

[chermann]

Sorry the noob question. I go trough a lot of threads but i found nothing that fits.

i need a converter from my laptop usb ---> to other digital outputs - e.g. spdif

my actually DAC has a lot of digital inputs but just anlaog outputs. i want to go with spdif in some tests amps and not over analog...

i found that....

SMSL X-USB XMOS USB zu Koaxialem Optischem IIS Digital: Amazon.de: Elektronik

your feedback please.

Haven´t used that before.

thanks...

i want to avoid to install every test amp over usb interface on my laptop. so my idea is to have one converter (one installation) and so i can connect this to all test amps over spdif.

so you are looking for an usb-soundcard with digital out?

hi Juergen

i run my music over Tidal and Yplay or Foobar and Jplay directly out of the USB port and then to the DAC. actually i have no idea what is possible to have topSQ and low price. i go trough a lot of Xmos boards but i have no idea...

I am using this SMSL USB bridge right now on Daphile. No problem so far. This may be out of the topic. I replaced all the SOT-23 regulators with better ones (ADP151) in order to verify the effect of Ian's FIFO. The result is that I couldn't tell the difference between them.

I'm currently using one of these for USB->S/PDIF. It also has a header for I2S output. And a grunt-grade onboard DAC (ES9023).

CM6631A???? USB?I2S/SPDIF???? 32/24Bit 192K??-???

Oh..yes the ESS9023 is really a good chip. If i checked the boards available in Aliexpress or amazon (it is because of delivery and warranty...delivery from overseas here in AUT ...our customs duty office want to have approx 20 euro !)) i didnt find the CM3361A Pro version.

on the pcb which you are showing is written Pro version.

thx chris

This one on Aliexpress has 'PRO' and 'Professional' on the silkscreening - 2017 CM6631A Digital interface 32 / 24Bit 192K Sound Card USB to I2S / SPDIF Coaxial Output Support Connect Decoder Upgrade DAC-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group

The vendor's based in China however. Guess that's inevitable.

I guarantee those WIMA caps are faked, because I have a bunch of them. However, it will still work though.

 

[abraxalito]

Ha, I pulled all those big red Wimas out of my board as I don't care for the sound of the DAC chip anyway. How did you tell they're faked? Measurements?

Yes, most of them are smaller in value, just out of tolerance. Measured by bench top LCR meter.

 

[abraxalito]

I might get around to measuring mine, if I can remember where I put them...

Check Aliexpress. Just type in "DAC case". Hope this helps.

Just reading over on ASR and found a poster there mentioned the SMSL x-USB. Its already boxed up and ready to go, has a nice feature of differential I2S output on an HDMI connector.

SMSL????X-usb???????USB?????IIS DSD 384kHz-???

Ha, now I see that's exactly the one you mentioned in the first post. Duh! You could try contacting the poster who recommended it on Head-Fi only to have all his posts deleted : Measurements and Review of Schiit Yggdrasil DAC | Page 7 | Audio Science Review (ASR) Forum

Forgot to mention, I believe this model is discontinued. You should make your decision quickly. There are others, but I still like SMSL. It's small and has OLED display which I think is useful.
