The arrangement for this little match was dictated by the cases I had to two Pis in. The one that I have in the main system would take the Micro usb cable and that had the SSP in it. Now me and SSP have a historyFirebug1 wrote:Terry, have you tried i/c other way round? Would that make margin bigger towards diy psu?
so I don't like messing with it. That dictated the way I connected the ICs and the PSUs. In any case, I thought that if I found the MkII PSU sounded better despite having the marginally inferior interconnect then it was definitely better.Listening last night to sources like Dusty in Memphis and Alison Moyet 'The Voice', I didn't think the difference so pronounced but I was getting tired.
To answer the question, I would expect that the margin would be larger the other way around. I may try that to verify (requires a bit of 'adjustment' to a Raspberry Pi case). I could try plugging both PSUs into the BMU (I've made a little 4 gang BS546 to BS1363 extension cable) - this is probably a better test since it eliminates the BMU effect to a larger degree.
Dave, I've actually wondered about a BMU to a BMU since I want to lay a dedicated spur in nice fat cable (cooker cable) to my listening room bith BS546 sockets. I think I have room near the distibution box to put in an Airlink type BMU. Building the BMU into the PSU itself I don't have enough knowledge to contemplate. I've got a Torroid which takes 240 v to 2 x 9v AC and then a little Chinese PSU (Audiowind) which takes the 9v AC and converts to 5v DC (which is what the Pi needs). I bought a torroid with two secondary windings because I was contemplating separating the power supply of the DAC bit from teh power supply of the computer bit.
