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/

I'm after my humble mod. Few years back I've replaced IV resistors to the foil ones. Now I have changed: 1. Vcom capacitors to hermetically sealed solid tantalums 2. 22uF capacitor for the LT3042 aka Xoverman's mod 3. PSU amanero upgrade according to b0bb's instructions. To cut the long story...

Ps. I have desoldered the amanero PSU board without any problems.

Guys, my biggest fear becomes a reality. I have a problem with desoldering the components from the PCB. To desolder I'm using the soldering station with a regulated temperature, high quality flux and copper wick. The method - I apply flux, then through the copper wick I hot the solder with...

For those still using the LM317s in the digital PSU possible mods are described below. Calculation of the minimal ESR for the given value of the output capacitor: http://www.acoustica.org.uk/t/3pin_reg_notes3.html 2200uF 16V Panasonic FRs in my 004 have to small ESR (18mOhm) than the...

Thanks b0bb, I'd like to confirm that these 4 x 33nF are not to be replaced for XLR users?

The caps will fit but is such o high capacitance (and 6.1A) recommended for the low power clock?

B0bb, Will there be any problem if I replace all four nichicon KGs in the digital PSUs to the same value 22k uF 25V CDE 380LXs? https://pl.mouser.com/ProductDetail/Cornell-Dubilier-CDE/380LX223M025J052?qs=Yar5Zvc6MhVVTvnR4qZ%252BCw%3D%3D I'm guessing that clock will be happy with higher...

The inductors are in my opinion the most difficult part to replace with the soldering iron. I will leave it as it is and only replace LM317s to LDOs + new FPCAPS. I hope it will be a good compromise.

B0bb, I have a problem with the screw on the right side of a photo, do you know if it could be disconnected?

Monolithic, Have you replaced the inductors in your DAC? Has it improved the sound or is it just a minor upgrade?
