If your top line budget is $2k then @ghdprentice gave solid advice. If I were in your shoes I would consider the Bluesound feeding your Rega and save the rest for when its time to upgrade. Bluesound seems to be the gateway drug to streaming although I have never used one.
@carlsbad is mostly right when advising against a streamer/dac but ONLY in the context of your budget. There are exceptional streamer/dacs that aren’t in your price range presently (DCS, Bricasti, Meitner, Totaldac, MSB, etc). Another option would be to stretch your budget into the $4-5k range and consider a product like the well reviewed Hifi Rose RS150b. It would serve as your hub and integrate everything analog or digital as well as any a/v needs.
