Considering the double chassis I'd been expecting £20K+ but hoping it'd be less

I have experienced dropouts which started after an andriod update reset defaults for power management settings for MALP, it may be worth checking that your streaming/control apps are set to not power save aggressively.

I compared it with several others items that can stream but mainly I wanted playback from my FLAC lossless collection, music from 50s to today, rock pop electronic and classical works, with a bit of Qobuz and Deezer to fill in. 1-samsing galaxy s23 ultra in flight mode using UAPP output via usb...

I've been using 2Go+2yu to feed M-scaler+Dave, the result are superb. I did find not so subtle worthwhile improvements using batteries to supply both 2Go and M-Scaler. Using FLAC off microSD and wireless for control so breaking any ground loops via ethernet produced another worthwhile gain.

I ran into a similar problem years ago with a Plenue DAP and it turned out to be 'illegal' characters in the file names or properties, things like o's with accents and c's with cedillas. It was slow work checking all the files 🙈

The most straightforward way to avoid rf from powerbanks or batteries is to not use anything with internal voltage converters. A 12v 17ah AGM/SLA type works well. I power 2go+2yu from 4x NiMH cells giving (near enough) 5v. I used 10ah D cells, 2 sets of 4 is around 94Wh nominal, again works well.

All of the iFi Elite PSUs have the DC plug -ve/gnd part connected to mains earth internally, I checked 5v 12v 15v models with a multimeter. This caused me a problem adding the iFi powered M-Scaler to DAVE as it created a ground loop and made anything connected via spdif or bnc have random...
