Michael shares his project files for a digital HiFi amp featuring a 20 W stereo power amplifier, 4 way audio in and digital volume control interface.
Though I am a musician I don’t care for calling an expensive hi watt stereo my own. For years I have used a homebuilt stereo amplifier built around the TDA1554Q IC (basically just this chip in a nice box) and I am still very happy with the sound quality. This amp serves as a computer desk sound system, which acts as a radio/movie sound system as well.
In the meantime the number of sound sources that I want to connect to my “stereo” has increased … suddenly there was a tablet that I use as an internet radio, a music player demon that runs on a raspberry pi and from time to time I want to listen to a podcast that I downloaded to my smartphone.
So a next-gen desktop stereo should have multiple inputs … about four of them would be nice. Also when watching TV on my computer from the bed I don’t want to get up all the time if I just want to adjust the volume. I’d like to do it digitally … maybe use my smart phone as a remote control?
