Review and Measurements of Topping D10 as USB to S/PDIF Converter

Ok I have to study this a little more in the future but will rely on you experts right now to tell me this is the best sound quality at an affordable price I can get. I’m playing mo3 and flax from iTunes. Sorry for the ignorant questions but I do plan to educate myself in the next few weeks
 
I just got this unit recently based on this thread and just wanted to say THANKS!!

Previously, for a USB-SPDIF converter I was using an IFI Micro something (can't recall the exact name) as well as some Uptone Audio BS and now since that junk has been removed my audio quality has jumped up considerably.

A veil of crap has been lifted and I can only assume that the D10 is doing what it's supposed to do and that is to be neutral and not color the sound. My system sounds less 'cluttered' with more detail.

One question......is it possible for the Uptone stuff (ISO-REGEN and LPS-1) to degrade over a 3-4 year period? It sure seemed like it did.....
 
So if you use the D10 as a USB to SPDIF converter, it gets the clock signal from the PCs USB port, retains it and sends it through SPDIF to the receiving DAC? Is that right @amirm? So it’s up to the receiving DACs SPDIF implementation to make sure the original USB clock is maintained without excess jitter?
 
Hello Amir,
Thanks for the review.

I would like to ask you... I have a Marantz PM 6005 which has only two digital S/PDIF ports, as you must know. And I am thinking about buy a Topping D10 DAC.
My doubt is: Should I use the D10 connected to the digital ports and using the Amp internal DAC or should I use the D10 connected to the Amp analog ports bypassing the Amp DAC?
What is the right option to the best sound quality?

Thanks in advance.

You'd have to measure the PM6005 internal DAC to make sure, but since the D10 is a known good DAC I would use it via analog to the Marantz. Then if still curious, try its digital in :) .
 
Thank you for your answer. May I ask you something more?
I still don't have an external DAC. So, what about the sound quality of SMSL M100 and the Marantz PM6005 internal DAC?
I would like to enjoy my flac files on my amp, but it has only S/PDIF ports and the M100 has only analogic output port.

Regards
 
Your "amp", which I assume here means PM6005, has both digital and analog input ports. And again, without PM6005 measurements, there's no comparing its DAC quality/qualities to other DAC's.

Personally, I doubt one would notice any difference among all the DAC solutions unless the most important things for good sound quality have first been addressed (speaker quality/qualities, and proper in room setup/correction in relation to listening position(s)):

Thank you very much!
 
Hello a few quiestions
I want to use d10 as a converter with windows 8 and another dac...

Will the other dac or the d10 show in device manager?

Will the d10 need a driver?

And finally

When configuring foobar output, will the d10 or the other dac show as the output device?

Thank you anD happy new year!
 
For anyone who currently has this dac, I know it’s USB class 2, but does it have a USB class one “mode” which can be used? I’m wondering if I can use this to get coaxial audio out of a PlayStation 5 but the console will only work with USB class 1 audio devices. I’m aware of hdmi audio extractors but for my setup usb to spdif would be more convenient than two hdmi cables and having to buy a more expensive extractor to get 4K 120hz pass through. The Fiio k3 I know has a class 1/2 switch, so that may be the best option but I would prefer the Topping if possible
 
I have a question - if I use the Topping D10 as USB to SPDIF converter in order to clean the USB signal from jitter, will it pass through MQA so that my SMSL M500 (full decoder) can decode it? I use Raspberry pi 4 with Volumio as a streamer and source and I am concerned with the quality of USB signal I am getting from it. What I am thinking to do is to go from raspberry pi 4 with USB to Topping D10 and from that with SPDIF to SMSL M500. Thank you in advance for any advice on that issue.
 
I ended up using the Cubilux USB-C to Optical converter to hook up my iPad to my “legacy” DAC integrated into my stereo amplifier that has optical inputs. Works amazingly well and the results beat using Schiit Modi 3 as a DAC to the stereo amplifier!

What beats me is how Cubilux has gotten a converter that small. Here it is compared to an XMOS XU208 converter. Anyone have any ideas?
 
Erm as we are talking about small usb to spdif converters… have a look at the SMSL PO100 for $40
I think I might have figured it out. Pretty clever.

It a DAC to ADC implemented. DAC is on the USB and ADC on the Toslink end.
id hope that wasn’t what it is… that’s really bad… more likely a digital to digital bridge, that would be small enough to fit in instead of two converters

How would a digital to digital bridge work? Look at the other XMOS implements and they are pretty big compared to this one
