You can purchase an extremely affordable Toppings D10(s) to work as a USB to SPDIF (rca or toslink) output.
There are many ways to attempt to improve performance in a DAC. There are components like the Schiit Wyrd but some say it's useless. Wyred4Sound has a re-clocker. Holo Audio Titanis is another inexpensive bolt on that has merits. Sometimes collectively combining several components will help clean source.
Purchasing an expensive USB cable can help. This is where possibly a higher quality boutique cable can reject noise better. This is where some assume a passive wire can fix dirty signal. So much has changed in modern day streaming knowledge in the digital streaming world.
I have tried different DDC like the galvanically isolated Resonessence Labs Concero HD (as DDC), April Music Stello U3, Toppings D10s and (s). Stello U3 sounded warm and clouded details while the rest was transparent and clean. All worked well in performance. All did NOT remove digital glare because those units do not re-clock.
Adding linear power supplies do help in sonics. For example the Mytek Liberty or Brooklyn+ sound terrible without one. Using the mediocre switching power supplies certainly hinders SQ. This is why it's worthy to purchase a clean Linear power supply for that product. This is where a linear power supply is not "fixing" the source streaming data being fed to the digital to analog stage.
Denafrips puts effort into cleaning input stage of Pontus, Venus and Terminator because they know this is taking care of the primary problem with D to A conversion.
At this point in time the overseas market hasn't taken hold of this area in illegally replicating ccts and design. In due time such re-clockers will be cheap around the world.
When that time comes people will open their eyes and achieve almost "end game" status in ultra low jitter. We are still in the infancy of the "realities" of how crucial Digital DATA is to D to A music reproduction. Observe how my post has created "questions".
Oddly, I entice thought yet many are still assuming the only path of analog bliss is to buy a much higher end Venus or Terminator. Indeed such dacs are more involved in R&D and higher in the audio food chain. However, eventually when people understand jitter reduction, buying an SMSL M400 and feeding it ultra low jitter may be hitting endgame status vs buying a 3-10++ grand DAC.
I am stating such a thing is because amongst people I know and personal experience, it's ridiculously obvious in sonic improvements by emphasizing on cleaning "Source".
999€ is not chump change. Reproduced music cannot easily replace real live concerts. Due to Covid, I'm not cool with high density concerts now, possibly ever. In home, I have now achieved a certain level of SQ that satisfies me. The journey has not hit endgame for me but it's at the point of still picking up my jaw off the ground.
From auditioning DACS I know cannot take it as face value as I know the source is contaminated with jitter garbage. So if you've played with Denafrips, Border Patrol, MHDT Lab, IFI NEO IDSD, RME, Toppings, SMSL, FIIO, CHORD, Bryson, Simaudio......the typical and usual suspects. Garbage "in" will always = garbage out, not matter the brand. These are facts we cannot ignore anymore. So my knowledge of clean source will NEVER RATE a dac until I feed it "ideal" input source.
Compare a Bryston BDA3 (under 4 grand) to a SMSL M400 (1 grand). Different DACS and some may be envious of the owner ship of the 4 grand dac. Both DACS will become more fluid and relaxed with analog real world ease with a re-clocking DDC. Personally speaking this is something I can say is impossible with a Schiit Eatr DDC or any regular DDC. Painfully creating endgame in purchasing a re-clocking DDC can make the ARES II possibly almost endgame happiness. Such a combo of Mutec/Ares II can elevate you to audio bliss and make the Bryston BDA3 sound like a hyper detailed fatiguing expensive DAC.
If you own an ARES II and feel it will go to the buy/sell forums to upgrade to a Venus ii. I strongly urge you to work on your source "cleanse" first.
People........fix the problem directly. This is where I suggest upgrading in the DAC after. Pontus, venus and Terminator with a single stage is attempting to clean the source input problem internally in the DAC.
Either buy a streamer/server with ultra low jitter with involved cct and design to re-clock signal or use a CHEAPER streamer/laptop and downstream 100% fix the problem by reducing Jitter with a Reclocking DDC. Truly not complicated at all.
NOTE: all of the SQ improvements is from downstream. The SQ analog bliss improvements is coming from the re-clocking DDC....NOT the laptop/streamer.
Interesting how many feel it's the DAC that is the most major sound changer. It's the tool that translates "dirty or clean" source!!!!!!!!!!!!!!!!!!!!! Chain of events is crucial in digital. You can always run out and buy a $500-20K DAC. Only the latter will have the high tech input cleanse of jitter. Have you ever heard a cheaper DAC fed with amazing ultra low jitter signal? The answer to most is "NO". I will say you do not know what you are missing.......Once you experience such a thing you'll be in for a shock.
