I've been recording at 24/44.1 for years for that exact reason, but oddly enough, for just the past few shows I've been recording at 24/48.
For my own listening, for quite some time now it has been mp3's on an ipod/iphone/ipad for car and on-the-go listening, 24 bit listening on my computer (I have a pretty good computer playback system), or 24 bit listening via a Squeezebox (which does 24/48 natively) for my main playback system.
Given that I have no need for 44.1k sampling, I've just started recording at 48k, somewhat as an experiment to see if I'm ok adding in the additional 48>44 processing step for those who want CDR listening. That mainly as a time and workflow issue, not a sound quality issue. I guess what I really should do is start sharing my 24bit filesets along with the 16bit filesets for those who care for the highest quality.
Frankly, I seem to be in the very small minority who feel that 16bit flacs are actually lossy versions of my recordings, not lossless (um, I threw out 33% of the information, how is that lossless?). In that vein, I've somewhat stopped worrying about having the best quality for 16bit filesets. As an example, I picked up Wave Editor which has Ozone's MBit+ dither algo which I find to be excellent. But I never dug WE as my editor, so for a while I tried editing in Amadeus, then loading the 24bit file into WE for MBit dithering. I found I just wasn't motivated for the extra time, so now I just dither with the free mda dither plugin available in Amadeus.
I have no idea how good that dither routine is, and really don't know whether a 320kbs mp3 made directly from a 24/48 fileset sounds better than a 16/44.1 flac fileset that has been dithered down with the probably pretty crappy mda dither routine and then re-sampled to 44.1 with the basic resampler in Amadeus. I have no doubt I could do a better job putting together a 16/44 fileset if I used only the best dither routines and re-sampling programs, but at that point, isn't it easier and better to just provide the original 24/48 fileset to those who care about the quality?
No offense intended to those who want quality but are limited to 16bit listening. Then again, it is getting pretty easy to do 24bit listening these days, perhaps time to upgrade to 24bit if you are in that camp.
