If you’ve ever wanted high quality sound from the Raspberry Pi, look no further than this High End Audio Bundle from
High End Audio Bundle
This bundle includes the following boards:

There’s also an option to include a 3A 5V power supply with the bundle.

This bundle plugs directly onto the Raspberry Pi like any other hat, and then you can set the audio as per normal with Alsamixer.
With the Kali hat plugged in, you can power the Pi from the Kali hat rather than needing another power supply. The Kali also powers the Piano DAC.

The Piano DAC can be setup in a 2.0, 2.1, or a 2.2 setup with crossover settings in the GUI. It uses dual PCM5142 DACs with integrated DSP, and comes preset as a 2.1 setup, but can be reconfigured via the PurePath software.

The last part of the bundle is the Volt Amp which uses a TPA3118 chip. It has 4 output filters, 4 EMI Snubbers, 4 bootstrap capacitors and gain setting components.

This whole bundle can be purchased from the Allo Website and for a limited amount of time, you can get a 5% discount by using the coupon code SIRLAGZ5
