just to get the mqa schtick clear - there are 3 unfolds in total
first unfolds if the streamer can deliver 96khz, then the dac does the balance of the unfolding/rendering
folks who have sorted through this often feel that the first unfold gets you most of the mqa sound quality benefit, like some 2/3 or 3/4 of the way there
bluesound or brooklyn or metrum (amber) as mentioned can all do the first unfold, or be set to deliver in ’pass through’ mode and let a fully mqa-capable dac do it all
current metrum and sonnet dacs have optional mqa modules that let them do the full unfolds as well as others... so do some NAD products that have internal DACs (but be careful with the NAD stuff, they sound very mediocre)
also, be careful about numerous Chinese DACs (Topping, Gustard, SMSL etc etc) that purport to be fully MQA capable, but they only do that properly if fed a stream via their USB input ... their spdif inputs will not do it... ask me how I know HAHAHA
**********************************************************************
then there is the whole question of how much difference MQA makes at all, versus an excellent non MQA DAC... but i won’t open that can of worms here
