I recently built one with universal PCB, point to point soldering. Connects to Pi 4B via 40 pin GPIO connector. Philips resistors and Bennic FPP output capacitors. Linear power supply.
Sound quality is surprisingly good. Warm and musical.
Total component cost to me is about US$15 (without chassis and display). Cost varies a lot with the output capacitors.
