Streamer matching to system

I am looking to upgrade from my blusound node. I am running a McIntosh MA5300 integrated amp with Revel f208’s and a velodyne DD10 sub with iPad as control interface. I am looking for recommendations for a hifi streamer & digital transport that can store digitally purchased hi res music files. The innuous models come to mind but wondering if there are other products / solutions that I should demo? Some other considerations:  very open to used gear, no limitations on space to house the solution, MQA is not required as I prefer Qobuz, trying to stick close to $3k budget. Cheers!
