Combination streamer and music server…without DAC

Re. Combination streamer and music server without DAC:  There don’t seem to be too many of these out there and when I do see them, they tend to be quite pricey (Aurender N20).  I would like to use the DAC on my CD player.  I’m looking for something used, between $3K and $4K.  I suppose Lumin is an option by purchasing an L1 storage unit but I’m trying to avoid having another box.  I have about 300 to 400 cd’s.  Any suggestions?  Thanks.
