Yea but he would be better off putting the PS in a separate case, I reckon!
The problem with the whole PC audio field, (I've said before, so forgive me repeating myself) is that we are using a general purpose tool to do a very specific task & the parameters have not been ironed out fully. There are no theories/guidelines that can direct us, just trial & error. So everything is open for experiment - maybe that's why we get the crazy stuff recently posted on Jplay forum re sonic harmonisers, quantum chips, black bodies, etc.
Still, it's good to keep an open mind, just not too open or madness invades.

suppose it is a little tight in there,
when its tight for space like that its a pain to build, i wouldn't have bothered trying to make it fit, but if i had a big case with plenty of room i would have had considered it.
Do you think there'd be interference with all this in close proximity ?
its a pity we cant hear pictures

Nige, there might be interference alright but who knows - it's just that the computer environment is rife with RFI, EMI & all sorts of transmitted noise, why put a low noise? linear supply in that environment also?
Like your pics - do you notice any improvement when powering the USB stick externally?

its a usb3 power injector i made but i have not tried it yet

I agree on the overall build John but I was posting more to show the Linear Supply which looks like a beast.
I am still on the fence whether to strip the Teddy Pardo and install it in the Zuma for all the reasons you mentioned, especially as it is working so well outside.
If I can come up with a good shielding solution I will install it in the case at some point.
It would be good to find someone in Europe who could build and supply a good linear supply for PC audio besides Paul Hynes as it seems he is not getting his work out the door at the moment, some people appear to be waiting up to a year for his work!
Pics of inside Teddy Pardo, if I had seen these before buying I would probably have passed it up but after hearing the difference I would have paid a lot more for it!!

Huh, that PCB is almost unpopulated - can't open up the pic to get a close-up look at how many parts are actually in there & what they might be doing!
This reminds me of a circuit that might be useful here - JLH Ripple-eater (John Lindsey Hood) - pcbb boards were sold some time ago - I'll dig up the link, if I can find it. It would be perfect after a AMPS inside a PC build - it cuts down noise & ripple to negligible levels, apparently.

See link this smps is priced at €95 in radionics so at least you know where some of your cash went to. I wonder how much teddy charges for his box of tricks by itself? I wonder if I dropped over my maplin supply would it be worth you comparing it to the pardo? At this moment Pearse you are comparing it to your smps. Just wonder if the maplin will give you a similar experience? Of course I will have to break it out of its box so will be keeping it but no matter as mister pardo is priced too high for me at present.Also the plex linear supply is further away time wise then I thought so will need something to power the zuma
Surprised with how little there was on there too John, there is only about one fifth of the board populated with 2 triacs or somewhat like that underneath using the case as heatsink.
