Alright, I will concede that Opus at 160kbps is really good. I always knew at low bitrates it was better than mp3 but I have not used it in awhile. I store everything in flac.

But if anyone else wants to compare: opus-bitrates.anthum.com lets you compare various bit rates of Opus. I think I hear a high end distortion in 160 that I don’t hear in the 512, but it could be expectation.
