Meant to say, you can just squeeze a Tokin supercap under each USB socket if you're handy with a soldering iron. Oh that's an interesting idea. What value supercap have you used? BTW I got the same reg that you used with the perspex covers and V/I display.

Tokin 47kuF 5.5V. I published a photo somewhere... 2nd photo in this post.

I think it's time for me to acquire a RPi and see what it's all about. I've been trying to find out if it is possible to connect the Pi USB wise to my Luckit WaveIO USB to I2S converter that in turn feeds into Najda. I need a little help before taking the plunge to check it will work with WaveIO. I contacted Lucian who designs the WaveIO but the answer was a bit inconclusive.. Essentially early Pi not fast enough. Later ones could be okay.. His website says Driver Support: No drivers needed for MAC OS version 10.6.4 and above No driver installation required for Linux with UAC2 compliant kernel ASIO / KS / WASAPI / Direct Sound drivers for Windows XP to 10 (32 and 64 bit) Fully featured genuine Thesycon driver package with NO periodic beeps We do NOT offer XMOS driver packages with limited functionality – as per this document Native DSD driver support and other features available only to genuine Thesycon packages! Latest Thesycon version of Windows drivers (v4.14.0) is available for use. Does any of that help me know? Then I read this link
Then more positively from way back... link

It seems a shame that the Pi, which uses I2S as a transport to add-on boards, would need to output USB only to be re-converted to I2S for input into the Nadja. Can the Nadja take S/PDIF input? The reason I ask is that, with a DigiOne board, you have the best quality lowest jitter output possible and the proof is in the sound quality, which is superb.

Yes, read that RPi can do I2S after I'd posted.. Thing is, the WaveIO I2S to Najda in is a very 'hard' connection. Umpteen point to point wires all shorter than 4cm by necessity. I suppose the RPi I2S way in would be the same? It's not something I could easily switch between. Perhaps RPi could replace it for all my needs but not sure.. Yes, S/PDIF is there both optical and RCA. I2S is widely tested and reported as the best way into Najda, the WaveIO board is widely reported as the best USB to I2S converter - dilemma Still confused.

Hmm, wrote a lot but lost it all in a comms / gateway error - had a few of those this morning on here... Saw the RPi does I2S after I'd wrote the above. I2S into Najda is upteen 4cm long point to point connections. I suppose if RPi would cover all my needs I could do away with WaveIO. Bit of a leap of faith with all the clicky pop reports though.. Yep, Najda has a S/PDIF optical and RCA. It's widely tested and reported that the I2S way into Najda is the best. I'll look at DigiOne. It would seem to be the safest way to get it working trouble free.

The problem with I2S is the need to keep connections very short and I don't think any of the streamer builds like Volumio support I2S output.
S/PDIF via the DigiOne add-on board is a good way to go and does a great job of separating out the digital noise of the Pi from its clean jitter-free output.
If you want to be sure about the SQ, why not pop over and have a listen? I'm not doing anything much this weekend.

Tempting Martin, very kind offer. Can't make this Weekend though Ideally I'd like to compare it to my current digital front end in my system

Resistance is futile, Steve. You will be assimilated by The Borg Pi.

Keep us in the loop with this Steve, I've been considering the same. I have a Korus Win10/MC24 server, but I've read comment elsewhere about an alleged improvement in SQ with a Pi, hence my interest

It's the USBridge, it's a smidgen better than the Pi - it's USB only. Allo Allo.

If I remember your Nadja is USB input only so hence recommendation I heard the USB bridge recently and it is very good and as Clive points out a little bit better than the DigiOne

The Najda has SPDIF, Optical, USB/I2S and Analogue inputs; I used to run mine via a Wavio board.
I am currently running my RPi into a DAM1021 ladder dac using the I2S outputs on a Kali isolator/reclocker; the wires from Kali to DAM1021 are longer than 4cm without any problems. Software used is pCP (Pi Core Player).
I would think that the Nadja could be run directly from the RPi without the need for the Wavio converter.
I have run an RPi / DigiOne / SEG but my preference runs to the DAM1021. I have not done any mods to my SEG and it is running from a home built 12volt psi - at some point I must give Stan’s New psu a tryout.
Jusr re-read John’s post about the usb input - I thought that all Najda boards had the full set of inputs with options being set via software/firmware.

About a dozen posts up... ...Yep, Najda has a S/PDIF optical and RCA.
