I am currently checking the final sample. It's much delayed, unfortunately, but has become even better with specs and extra features.

I am picking up my ADI-2/4 Pro SE tomorrow, and I am REALLY excited about this PSU!

Any news on when we can expect any news? haha

The DPS-2 should be presented and start shipping at the Munich Hi-End show. Together with the other two power supplies, the LNI-2 PS and LNI-2 DC. Details will be released then.

Maybe:
Standby operation only with the switched-mode power supply due to Directive (EC) No 278/2009.
https://eur-lex.europa.eu/legal-content … 32009R0278

Automatic switching on of the linear power supply unit (transformer) via the load request. The current mains voltage (115 or 230 volts AC) is automatically taken into account (bistable relay).

Housing as for ADI-2/4 PRO SE, so that extensions (battery, ...) can be installed later.

Like probably others, I am surprised that RME now wants to build a DPS-2 power supply in series:

" ... Therefore the ADI-2 ... achieves its technical specs even with less optimal power supplies. Or in other words: the choice of power supply is not critical."

...
"Technically the only improvement you could get is through perfect galvanic isolation to prevent AC leakage currents, a typical side-effect of switching power supplies. A linear one will not show that phenomenom. BUT the effect (if it shows up at all, simple grounding already removes it completely) is nothing more than a low level hum at around -130 dB. Not audible, and not causing mysterious jitter effects or similar which could change the 'sound' as such."

Review and Measurements of the HDPlex 200W Supply
https://www.audiosciencereview.com/foru … pply.7713/

If someone uses the ADI-2 DAC / PRO only for listening and is not able, for example, to determine whether the SPDIF cable is good or bad, they don't need the DPS-2.
If someone uses the ADI-2 DAC / PRO - especially the ADI-2/4 PRO SE in RIAA mode - for measuring, DPS-2 probably has advantages in the area of background noise.

RME should promote a DSP-2 only for measurement use, so that some people don't remember the negative business model of e.g. CYRUS (PSX-R, PSU-XR) ... Of course, RME will not be able to exclude that there are some people who buy a DSP-2 for better listening.

Interesting spectral analyses of the output voltages of a power supply unit at +12 V, 1 A top or +12 V, 0.1 A bottom (errors in the text, but diagrams are correctly labelled) in comparison with the spectral analyses of the DSP-2 soon to be presented.

Nice, thank you!

See you at Munich then.

Will the DPS-2 (or the LNI) power supplies be compatible with the ADI 2 Dac FS (sounds like the DPS might be?), and could you expect any improvement in sound quality from using them?

Why should one add then this box to the system?

Cause some people will hear a difference

reparability, and reliability pretty much, switch mode psu's performance gets worse as the caps in them age and they aren't very reparable since you have to destroy the case to open them, those psus can also be used with non rme products where they might make a difference.
