Plus with the single box I would be likely to loose flexibility unless I spent quite a lot.
    Sorry to hijack the thread but I'm after some advice on using my Pi3 into a Bushmaster mk1. I'm currently using a coax out direct from my PC motherboard into the Bushmaster. Im finding it hard to find relevant info on whether replacing this with a dedicated RPI with digital out would improve SQ?

    I've got a RPI3 laying around so would just need to get the digital out sorted.

    the digione coax board is an excellent hat. not cheap but its good value. fits onto an rpi3

    I know this is a pretty open ended question but: Would an RPI be a SQ improvement over my current PC setup? There seems to be so many things to consider in this regard. PC hardware, software, Windows resampling etc etc.

    i use an Allo Digione too. No question that it is far superior to a typical PC setup.

    What differences are there between the Digione and say a Hifiberry Digi+ pro in terms of SQ?

    First and foremost using any Pi with any Digi hat will be at least as good , in my opinion better than using a PC . A PC is a very electrically noisy enviroment and is constantly doing other things as well as sending the digital signal to your DAC. The good thing about a Pi is that you can either dedicate it to single use (Streamer , Player ) or if you have to use it as both streamer and player. This means all of its functions are aimed at this and nothing else . It will sound excellent straight out of the box and using a standard Raspberry Pi wallwart power supply . I have found though that the addition of a Linear Power Supply does improve the SQ quite a bit and if you are using a Pi as your stand alone server then an upgrade to the latest model Pi 4 offers a very noticable improvement in sound quality . Adding an LPSU to this gives additional improvement.

    With regard to the addition of an LPSU there are some really expensive units which will work but I would suggest that looking for a decent used one on e-bay or in the classifieds on the various forums is a better use of money . Yes you can pay lots and i am sure it will sound very good but you will get probably 80% of the improvement with a much cheaper but decent unit. I recently picked up an SMCL P-2 for around £45 and provided you use it on players only (it does not have enough power for a Server plus USB HD which is power hungry you do need a full 3 amp pSU for this) it sounds very good indeed and is beautifully made for the price .

    Just to add my tuppence worth. Have used Hifiberry Digi hats with Pi2, 3, 3B over the years. All been excellent, fed coax into into Beresford or Marantz Dac's.
    Now using Pi4 without hat. Usb direct to dac, and to my ears fairly significant improvement. No idea how, why what...just sounds better to me.

    On the Pi4 they cleaned up the usb connection

    I would suggest this has made a huge difference. If using Pi 4 and usb no need for hat.

    Yes, the Rpi 4 has addressed earlier design errors with the USB bus and I am sure that audio now sounds better through that port on the new model. However, I seriously doubt that a raw RPi4 usb device could compete with with a well engineered Pi Hat combo for SQ. I would suggest you try and hear an RPi with an Allo Digone board or something of similar quality.
