I can not really see the use case. It is too weak for an amplifier and for a preamplifier there are not the best input/output.
You could use Rpi 4B + HifiBerry DAC2 HD hat instead. It can be connected to a 2x1000W amplifier and two SVS PB-16 Ultra for a decent stereo music experience.
Does it do ble auracast?
I bought a cheaper (~$25) t-amp with a USB DAC in it on Amazon, for use with some cheap speakers from Best Buy. I was quite happy with it.
But these are mainly useful with very small speakers. For larger sets you need more than 100 watts RMS per channel.
