    Default Headphone Amp and Dac for Raspberry Pi

    Hi Everyone !

    New to the forum. Setting up a desktop listening system.

    Thinking:
    Wi-Fi > Raspberry Pi with Wi Fi >Volumio > Digi + > AK4396 Dac > Lehmann Clone

    Would welcome any suggestions.

    Trying to keep the costs down to less than $200 plus Raspberry Pi. Not sure if better to use Digi + and an inexpensive DAC or DAC + and a headphone amp.

    One thought is Raspberry Pi > DAC + > Lehmann Clone

    Also very interested in people using linear power supplies with Raspberry Pi / DAC +

    Headphones:
    * Sennheiser HD650
    * Sony MDR-7506
    * Denon D2000
    * Fostex t50rp

    Thank you !

    I would be tempted to go the Pi +IQ dac board route with the iFi iPower psu, folks are reporting good results with this combo.
    I tried the Pi with Digi+ board into my dac (with the iFi iPower psu) and didn't get as good a result.

    Thank you roob,
    Just looked at the IQ dac looks interesting, uses Texas Instruments PCM5122. The iFi iPower psu also looks good.

    Are you using speakers or headphones ?

    All the best,

    Dear struth,
    Thank you, which linear power supply do you use ? All of the ones I have found are very expensive.

    Found this on ebay Linear Power

    All the best,

    I was running the Pi and Digi+ into my main system, I tried the iFi Power psu but it didn't make any difference to my set up but other users on here who use the IQ dac report a good improvement over the stock psu. The linear psu you linked to does look interesting but you will need a mini usb adaptor to plug into the Pi, maybe the seller can supply one.

    Thank you Andy,
    It seems that you can solder a jumper onto the board and power the board directly:
