It measures terribly: https://www.audioscienc
Like, it's broken, it's so bad. Embarrassing for Fosi.
those measurements from ASR are so wonky

USB, usually.
Redundant and probably much lower quality than your Yamaha.
This will mess up your frequency response. It's a broken DAC.
Some schitt products are terrible and some are quite excellent. Few are a value for the money. Look up measurements.
If you want to listen to music, there are many quality DAC choices out there. A good one will cost a bit more. If you want an all in one solution with quality dac, adc, and headphone amp, you're not going to find it for cheap, and it's sitll going to perform badly with a junky gaming headphone mic. If you're streaming, you should use separates and a proper ADC. If you're gaming, just plug into the headphone plug on the PC.
Consider trying their SK02 if this option doesn't suit your needs. I personally use the SK02 as a DAC and the SK01 as a preamp for my mono HiFi system (2 ZA3s), and they work wonderfully for me. This isn't an all-in-one device; they offer specific products tailored to different needs.

There are concepts in digital signals related to link budget, but that is typically reserved for RF transmissions where signal to noise is an actual parameter in bandwidth derminations and protocol adjustments (like wifi when the speed goes up or down depending on SNR). In these cases you are truly dealing with packet loss and periods of time when the analog signals can't get through and be properly interpreted.
However with something like USB over short differences it's not a thing. The connection is either good or bad and it is expected that the signal integrity is way above any noise floors. That is one of the reasons USB doesn't bother with error correction, just CRC based error detection in case there is catastrophic packet failure (which computers don't really handle gracefully since it isn't an expected behavior to lose USB packets). CRCs on protocols like USB are intended as a hail mary since, again, the transceivers are expected to work, and they do unless something is out of compliance.
TLDR, you will never see a change in audio quality as a result of the USB signal's "noise" outside of the audio dropping out of the device disconnecting. UNLESS you have terrible filtering in your DAC and the noise is leaking into your analog, but that's a whole other topic.

Remember that headphones don't have a linear response to power, so having some headroom is ideal. I prefer to have 2x the power just to be safe, but you probably don't need that much headroom.

Not really
