- Raspberry PI 3+ with Volumio
- Mostly listening to Spotify using the Volumio plugin.
- Speakers DALI Zensor 5AX. These are super nice floor speakers with built-in class-D amp.
- The speakers only have 2 wired inputs - spdif optical and 3.5mm jack + BT (Apt-X).
If I play Spotify on my phone and use the BT link to play the speakers sound great, and very loud (subjectively, for me) but If I move more than a few meters from the speakers the sound becomes choppy, and besides I already have the PI lying around so might as well use it.
If I play Spotify on the Volumio, connected with 3.5mm jack to the speakers they can’t play very loud, even if the volume is 100% on the speakers. I suppose the output from the standard PI is just too low?
- Is it possible to connect the PI to the speakers using BT, or is BT on the PI only usable for input?
- If not what is the best solution? Buying a DAC hat? What would be the best to get?
I’m not a fanatic, I don’t intend to buy special power supplies and other things I see people discuss, but just pump it up to a normal listening level.
I notice DAC hats come with a combination of RCA, jack, coax and spdif options.
- So, if a DAC is a digital-to-analog converter, does it make any sense to output the signal digitally (spdif) ?
- I suppose both RCA and jack outputs will work with the jack input on the speakers, but will the level be better/louder than what I get from the PI now?
- Given coax isn’t an option on the speakers, should I use RCA/jack or spdif?
