I would rate the impact of introducing HQPlayer as similar to what I achieved from a major headphone/speaker upgrade.Īfter much experimenting I've found an inexpensive Pi4 is able to run sophisticated HQPlayer digital reconstruction filters that greatly exceed the capability built into DACs. In this article I'll show how to set up HQPlayer quickly, and the settings I've ended up using, as well as explain the process to get there.

The right filters, applied with a powerful CPU, reconstruct digital music in a way that feels substantially more real and engaging than relying solely on a DAC. HQPlayer can make a huge difference to your audio quality. I'll post comments when there are major updates to the article. Some SBAFriends 'reserve' initial posts, and I'll try that and treat the first few posts of this thread as an article, with later posts as comments.

I've decided to make a dedicated thread per tip instead. I found the Volumio tips thread to be unmanageable because of the need to go back and correct and update instructions after feedback, a buggy release of Volumio etc.
