Setting up a streamer for a frien


Title should read FRIEND. (Couldn’t edit it.)

I have a friend who has upwards of 10,000 CDs and owns an Esoteric CD player and integrated amplifier.
He would like to investigate adding streaming to his system. He doesn’t want to spend a lot however.
I’m recommending the Bluesound Node streamer.
What DAC in the $1000 range would you recommend?
Is there any way he could hook up the streamer to the CD player and take advantage of its DAC?
