Buying HiRez files obliges us to take irreversible decisions since day one, particularly as the files are expensive and we must opt for an unique format, as some labels charge independently for DXD or DSD256 files.
In terms of bit density both formats are equal, so the usual advice is "get the native format". However, many times, perhaps most of the time considering certain sites, the DSD256 files have been mastered and this implies that they were converted to DXD for mastering - should we consider them "native DSD" even if they have gone through this phase? Or in these conditions the best format is the DXD file just after mastering?
Just see:
Some labels, like 2L, have chosen to record in the DXD format and release in DSD. This allow for more editing that is common to PCM. DSD as a "container" for DXD is a very suitable solution for delivering files to end users/music lovers. Some labels, like Channel Classics, choose to record in DSD and on occasion will convert to DXD for minor editing purposes. Some labels, like Blue Coast, record using the Sonoma system and limit their editing to stay in the DSD format. (from http://dsd-guide.com/faq/what-dxd-it-dsd#.V_6y6Mkasuc
