I mostly record concerts, classical or popular music. For up to a few tracks, I often record to DSD 5.6 or 2496. If possible, I record to surround. When the track count goes over say 8, I use 2448. The files are mastered at 2496 or whatever source format and brought down to 1644 at the last step. So I keep the hi res files for my own enjoyment and later, if someone requests higher quality material, I still have all the source files.
The not so funny thing is that noone ever does. I guess few have the knowledge about using higher quality audio unless it's an easily playable medium, like SACD. Most of my friends don't even care enough about their speaker placement to notice a difference.
A 2496 FLAC file has this airy feel to the sound that's really quite enjoyable for classical music and when I do purchase music, it's usually in surround 2496 FLAC from 2L. However Spotify and WiMP work well for most my needs. They sound good enough and are very convenient. And work in my mobile phones.
