IVX,
Amir measured much poorer S/N on Meizu Pro model. I am wondering if there are different modes on Meizu (both Pro and non-pro)., setable in firmware or software similar to Hidizs hifi mode, microphone mode, etc or ability to change filter type? There has to be an explanation for the difference in Amir's measurements as I suspect that Sonata HD Pro and Meizu Hifi (non pro) are just the naked chip output?

as I explained already, APx555 simply too noisy to measure modern DACs, even portable one like CS43131, not saying about top one like 4499 or 9038. I have no idea about Sonata HD Pro but Meizu Hifi (non pro) has no opamp onboard.

Regarding different results of Meizu HiFi DAC Pro measurement, I think the issue could be in a different USB 5V power rail quality. Such a compact DACs has near to zero caps on that rail and 5V rail isn't filtered at all, hence, the USB host 5V quality may affect a lot to the measurements. Or, maybe CS43131 has different THD grade as well, for example, I didn't see <-120db harmonics on my Meizu HiFi DAC non-Pro even no load, rther -115db i.e. as it claimed in the datasheet.

I swear, I still have no idea about you talking. If you really need to I understand your point, please help me.
Never mind... You said you measured up to 115 dB THD+N on non pro Meizu, that there's no whatsoever secondary buffer on it & I bought it (what you said). It turns out how output measurement is to strong for that to be a case (output straight) & people measure lot less (THD+N). Also lots of people complained around hire how there are problems with it regarding certain sampling rates which Pro doesn't have. In short that would be it.

Well if the Sonata HD Pro is a Hidizs S8 than obviously there's a secondary amp present. It's actually interesting that it gives more on 300 Ohm's load & less at 33 compared to Meizu Pro. We need a teardown to see which amp it is but Hidizs/TT is heavy glued...
I am not convinced even that Meizu HiFi (non pro) doesn't have some kind of it.

I have ordered the S8 and might take it apart if:
  • Amir hasn't reviewed the Sonata Pro at that point
  • Someone has a Sonata Pro that he would take apart (would be useless otherwise)
  • It doesn't sound any better than my 9038S or even my Meizu Pro

yeah, it should be about 5x5mm, however, Cirrus solution has a higher performance, and the same time easily fit into Meizu HiFi DAC, and seems nobody needs even smaller, right? Single-chip combo also offers realtek - ALC4050, VERY cheap even if you think it is a bridge only, however, there are ADC/DAC(soso quality), HPA, noise-canceling etc. 64KB flash onboard 6x6mm QFN $1.3-1.5/pcs if buy a reel 4900pcs. With switched Off DAC/ADC, USB bridge itself eats just 18mA from 5V, and the chip needs ONLY single 5V rail +4 decoupling caps and one 6.2K res. If compare with savitech sa9302, which needs 2pcs external voltage regulators(LDO + PWM buck converter for 1.8V/100mA!), external 24c256, external 12MHz, amateurs RCD reset and a lot of decoupling caps, ALC4050 looks like extraterrestrial tech and for 1/3 price ;)

ALC4050 as good as the CS43131 as standalone dongle chip? saw quite a few sellers for dongle using this cheap

Now we have High End in remarkebly small devices. I once modded a 2nd generation CD-Player with SPDIF out
SPDIF was NOT on Board, I had to use a DIT4096 transmitter from TI to generate SPDIF from Data - L/R Clock and Bitclock.
So, question:
Are there any small devices to generate USB from SPDIF and mimic an Android / IOS / Windows device?
Nothing fancy needed, just plain 16/44.1 at full scale.
Because the E1DA9038, Hidizs or Sonate fit everywhere and could upgrade the early machines...
