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.

A low noise psu of any type will make the pi dac sing i think.. Pleased with my linear one.

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:
