Is there a particular reason you don't opt for lossless formats (e.g. FLAC) for your music archive? I imagine the only constraint would be space, though storage gets cheaper by the year.
I use FLAC for storage, and Opus for playback. I.e. in essence I use both. The benefit of lossless is ability to re-encode later to any new codec (Opus-next?) if it will be useful. For playback, transparent Opus is good since it takes less space.
I.e. in practice - in my main archive I use FLAC. On some portable players and etc. I use Opus encoded from that FLAC.
That's why I always try to buy music in FLAC when possible and stores like Bandcamp are great for it.
