I’m also looking at doing this, so instead of starting a separate thread I’ll post here. I’ve got a Raspberry PI Mod-B and I think I need the following components:
Raspberry PI (obv) + DAC + Amp + Speakers.
I want to keep it to as few components as possible, as few power sockets as possible and to keep it all controllable from an Android app or web browser - no separate controls or remotes.
For the DAC part, I’m looking at the Wolfson Audio addon or the HifiBerry. I still haven’t figured out if the Wolfson also covers the amp requirement though - that would be great.
On the Amp part, I was looking at some of the mini T-Amps available on AliExpress but I think that increases the number of power sockets and introduces another control. So I’m now looking at active speakers which I seem to think have an amp built in; specifically I’m looking at active speakers which only require power to one speaker (the other is connected with a single cable) and also have auto-off function which means that if there is no music being played they will switch off and switch back on when music resumes. I don’t have any brands in mind yet.
If I can find some active speakers which also have a USB output powerful enough to run the Raspberry PI that would be a dream but I’m not holding my breath, so I’m prepared to go to 2 power sockets for now unless anyone has other bright ideas.
In fact I’d ditch the Raspberry PI completely if another platform (Cubox etc) meets the requirement but I don’t know enough about the alternatives yet.
Seems that there’s a gap in the market for a one-box stereo active speaker unit with a USB power out and a Raspberry PI-sized slot - that way we could easily bake our own Sonos Play 5 or 3 or 1 replacements…
Actually , whilst I’m thinking about it - does anyone know of active speakers with a HDMI input? The Raspberry has HDMI out which surely is digital already no?
