If you want to make hi-res playback from recordings you already bought, you can use Ferocious Resampler [

and upsample existing tracks preferably to even number - e.g. 16/44.1 to 24/88.2 or 16/88.2 (for mobile or where space is concern), 16/48 to 24/96 or 16/96.
There is no information above 20 kHz that can be heard, but most common DACs today oversample much worse than sw resamplers and therefore if existing tracks are upsampled playback quality can improve.
Generally 24 bit recording has sense and if you have 24 bit source it should be preserved in 24 bit, 16 bit can be used very well with dither but the quality is theoretically very slightly lower. But when upsampling from 16 bit sources and if space is concern (mobile) the upsampled results can be saved in 16 bit.
The original Hi-Res tracks can also sound better but that is mainly because of different/better mastering than CD or other existing media.
