For sale, one HiFiBerry Beocreate 4 channel DSP / DAC / amplifier with 24 V / 220 W Meanwell power supply, $175 shipped to anywhere in US.
The Beocreate consists of an ADAU1451 DSP / DAC and a 4 channel amplifier based on TPA3128D2 ICs. It has 2 higher power channels which use TPA3128D2s and 2 lower power channels which use a single TPA3128D2. It is meant to be used with a raspberry pi (not included) running HiFiBerry OS which allows you to program the DSP. It has TOSLINK I/O and can also act as a streamer through HiFiBerry OS.
The 220 W power supply is rather large but allows for the Beocreate to achieve rated power. I've personally measured the following power output:
High Power Channels
30 W x 2 @ 8 ohms, 0.2% THD+N, -3 dBFS input signal
60 W x 2 @ 4 ohms, 0.5% THD+N, -3 dBFS input signal
Low Power Channels
30 W x 2 @ 8 ohms, 0.2% THD+N, -3 dBFS input signal
30 W x 2 @ 4 ohms, 0.2% THD+N, -6 dBFS input signal
This is a great all in one solution for those that want to dabble in DIY active speakers at a very reasonable price. I have used it to implement LXmini DSP and it does great.
