I'm in the same boat. Foobar2000 is basically perfect with unlimited ways to customize it, a healthy DSP repository, etc etc. I run it on my windows box but also under WINE for OSX. Nothing else comes close as an all-in-one package for audio.
yeah -- its getting there. That last release was a result of me mentioning darkmode. It was easily the fastest 'can I post a bug somewhere?' to release I've ever seen. The total time was no more than a few minutes.
While the mac version is promising, its still missing the powerful organization features that I use the most.
Foobar2000 is probably my favorite and most-used piece of software.
