Hi b0bb, Could you share what PSU you are using? Thx.

Thank you for great review! Quote from your review: "The user has the choice of selecting digital volume control, in which case all attenuation is done in the digital domain by the SERCE processor" Are you sure that digital volume control in not done in the es9038pro? I would really love to...

New review (in Polish): https://highfidelity.pl/@main-4457&lang= It's interesting to see new solution in IV stage, powerful BUF634 combined with another opamp.

It would be great if you measure analogue volume control vs digital:)

They mastered the marketing, it's so simple. Brutal reality shows that there is 6dB difference in SINAD. It's a lot. https://goldensound.audio/2021/10/12/dcs-bartok-with-headphone-amp-measurements/

Unfortunately it seems that the implementation of high-end chips used in the 005 is wrong and the analog stage is too weak for the 2 x ess9038.

You could lower the level to 1.5v by using the digital volume control built-in ess9038.

Not a king of measurements, for sure it's worth to lower the level to 1.5v: https://www.audiosciencereview.com/forum/index.php?threads/musetec-audio-lks-audio-mh-da005-review-dac.34065/

Really nice done DAC, I see improvement over the 004.

Both LDOs are for the clock to provide the lowest noise voltage.

Probably it was the AKM spdif receiver.

Thanks for photos, could you please also attach some photos of the digital side? I'm especially interested what galvanic separation and line drivers are used in the 005.

Maybe thick rubber (used in industry, vibroisolation) between the enclosure and the toroids will do the job? https://www.wibroizolacjapolska.pl/wibroizolatory-do-maszyn-i-urzadzen/p28-wibroizolatory-wibroizolacyjne-elementy-gumowe-G/
