It is all too obscure and bleedin' complicated for me. I want a plug and play box.

Get a Sonos, Doc.

I am seriously not interested in buying one. I am only interested in one of our *experts* like Terry coming up with a plug and play box. The TFS was miles ahead musically than any thing else to do with computer audio. I had one and sold it as I will not keep anything from someone who tries to stitch me up (figlet108 / Jason). I miss it but my CD system was nearly on a par with it, my present CD system is way ahead of it. I have developed interest in Terry's project because he has a TFS and says it is on a par so I have interest, in a bog standard commercial product like a Sonus I have Zero interest.

Sorry, Doc. Didn't mean to offend. In a previous existence I was an IT programmer/analyst and so the computer audio area does interest me.
Seriously, I think the idea of combining your PSU with a dedicated source like the Pi could be very fruitful and I am watching with interest.

No offence mate. I have had a headache today so I am probably grumpy. I think I have a bug
The TFS looked lovely and sounded lovely, but it was a sad episode in NVA history.

Change of topic direction
Uncle Stan the super DAC man reckons too much current in his power supplies create noise in his delicate devices. One wonders might this apply to a) Raspberry Pi's b) onboard I2S communicated DACs.
I know the ample power of the AP10H drives most cans with pleasant ease. That is the electromechanical analogue world. Give them horse power and they motor. Pi and DACs are the antithesis. They do not love/thrive on loads of power - or am I just Mr D Luded of TAS?
There are those who can and the others
End of interruption.

Hang on a minute, much play was made with the new StanDAC's internal supplies, smoothing and regulation, way after the external supplies!

That is true but if you have an earlier(?) none super device then current = noise says Stan
Role up, role up, get your cheap and nasty versions cheap now. I must try one for the eye/ear opening experience that some speak of (just like mains cables)

Stan often says what puts down others and preens him, he is talking
It shows little knowledge to think larger available current means it is used, it is there to give bigger "pipes" for the musical water, so the musical flow is more easy and "liquid"
The term is source impedance.

My mate Alex has a Caiman mk1 (cap coupled direct output) and it's nice enough, but in a £500 Arcam kind of way. Sorry folks, but a Rega DAC totally out-performed it in the bass department and gave better 3-D too. To be honest, some of the Fiio DAC/headphone amps are at least as good for under £100 IMO
