WiiM Amp: Multiroom Streaming Amplifier | Compatible with AirPlay, Google Cast, Alexa | HDMI, Voice Control | Stream from Spotify, Amazon Music, Tidal & More | Silver

Find a used AVR or stereo receiver that has optical… no reason to dump a ton of money into the situation. Can literally find one for $50-$200 on Facebook marketplace and you’d be good to go. HDMI ARC or Optical > the receiver > the speakers with some speaker wire, done. Other route would be a DAC & Amp… but honestly, used receiver route will likely end up cheaper (I’d only go the dac and amp route if you want brand new, but don’t let brand new end up more than what it would cost to get a refurbished AVR): get this - FOSI AUDIO DA2120C … other options are a combo of these two, FOSI AUDIO Q4 & BT20A Pro (or the non-pro version, but I like the pro more)… WiiM Amp is also a nice option, but it’ll cost more than the prior two options I gave. Best choice is the DA2120C (best for beginners) for simplicity purposes. You go the Q4 & BT20A Pro route if upgrading speakers down the road and amp performance means a bit more to you (since it’s two separate pieces of hardware, you could always choose to keep the AMP and go for a better DAC as time passes).
