Power supply for HiFiBerry Amp2?

Thanks to advice from folks on this forum I’m now the proud owner of a couple of HiFiBerry Amp2s that will replace Sonos units. The Amp2s will drive 6ohm ceiling mounted speakers.

I can’t identify a suitable power supply that I’m confident is the right voltage (I think 18-20v?) and has the correct barrel adapter. Can anyone recommend something that’s working for them here in the UK?

Thanks in advance

“You only need a single 12-24V power supply to power the Raspberry Pi and the Amp2. With 4 Ohm speakers, we recommend 12-18V. Higher operating voltages are only recommended with 8 Ohm speakers. However, even with 8 Ohm speakers an 18V power supply is the best choice in our opinion.”

Thanks for the quick replies. I’ve seen the HiFiBerry comment on this but was looking for a source as I couldn’t find any suitable supplies. Thanks @Martin_Webster - can I just confirm this has the correct barrel size for the Amp2?

It comes with a 5.5mm barrel connector; same for IQaudiO Pi-Digi Amp and the HiFiBerry Amp2.


But you may want to go for this alternative which is recommeded by HiFiBerry:

Currently using the Hifberry 20v/80w power supply with an RPi4 Dac2HD and Aamp60, no mains lead is supplied.
