spdif to USB converter (such a thing)


Recommended Posts

Im trying to bypass my digital input / reclocker's spdif input. As the Oppo 105 only outputs audio via spdif / optical so i trying to find a spdif to usb converter. there seems to be no such thing.

 

if that is the case how to get around this issue?

 

thanks

I purchased a USB to spdif converter from Greg Osborne, can’t see why it wouldn’t work in either direction, might be worth asking him the question.

 

cheers,

Terry

They are almost without exception NOT bidirectional unfortunately. However MiniDSP make the most affordable one I could find and it works fine, though doesn't support 192 kHz (but everything below it.) I have one and can confirm it works fine.

thanks for that - unfortunately i need 192khz as many of my files are 24/192.

 

can you convert optical to RCA connectors?

That's called a DAC, unless you mean a single coaxial RCA?

So to get spdif / coax converted to USB you need 2 boxes? wonder what deterioration to the audio sign this will impact.

No I didn't say that. You asked two different questions.

Reason is that my digital reclocker box spdif and coax is the same connection. I think. 

 

Anyway i need minimum 24/196

Unfortunately that comes at much greater cost to convert to USB. Only the Mutec interfaces I'm aware will do coax and/or optical in and USB out at that rate. They cost about a grand.

The mutec mc3+USB is an amazing product (at a cost) and is effectively a swiss army kife. Has nearly every inout/output you could want plus high res/dsd. The USB port is bi-directional.

Awesome but $1k wow. thanks guys i will look into it.

 

The MC3+USB is actually closer to $1,750. There are lower models with less features but the MC3+USB does the lot. It either internally reclocks the signal, or can use the Mutec REF10 as an external clock. It has every input you could want, and lets you spit the signal out in whatever output you choose (including USB). It caters for pretty much every format as well (PCM/DSD). The swiss army knife of reclockers. I've spoken with quite a few from the pro audio space that are wowed by its performance and find it great value at it's price. Although in your application you may find it a little exxy :)

That said, its reclocking is precisely useless when you're going from spdif to USB so it is serious overkill to use it in the reverse direction.

You sure it doesn't do 192 kHz?

The manual states:

The Stereo firmware supports two input channels and two output channels at 44.1, 48, 88.2, 96, 176.4 and 192 kHz. The input channels are received on the optical input as TOSLINK and made available to the computer over USB.

Quite sure, as I have one and went digging into the specs when it wouldn't work at 192. It only works at 192 USB to toslink, but not the other way around.

Current design but only 96khz https://hifimediy.com/product/hifime-ur23-spdif-optical-to-usb-converter/

If I am reading the spec's right this can convert from optical to USB at 192khz https://hifimediy.com/product/hifime-uh1-384khz-usb-dac-headphone-amplifier-and-i2sdsd-interface/

thanks deep. the second one looks intriguing as it also supports i2S out. really want to do it without another dac into the mix. but this option is the best so far. thanks

@IttakuDo you mean reclocking is useless in this particular application, or the MC3+USB doesn't reclock when going from spdif to usb?

I mean reclocking is useless. The clock is designed to fix jitter of the spdif signal which has completely different timing to USB, and USB timing is separate and asynchronous from spdif so its timing all gets lost when to usb. Note it may provide different advantages in terms of ground loop isolation and preventing noise down the usb signal, but the timing component is the main reason for having an expensive reclocker.
