Rotel RA-1592, Parasound HINT5 or 6, Cambridge Audio Edge, Anthem STR integrated, Classe Sigma 2200i integrated, Lyngdorf TDAI 2700 or 3400, McIntosh MA6900, Naim Uniti Nova (streamer/DAC/integrated amp all in one box solution), Simaudio Evolution integrated or Neo Moon integrated, Rega Elicit-R, Rega Osiris.
The Rotel RA-1592 will be a big step up from the RA-1572. I have a Naim Uniti Nova paired with the B&W 805 D3 in my bedroom setup. I highly recommend the Naim Uniti Nova it's very musical very refined sounding unit. The Naim Uniti Nova is an all-in-one box solution (streamer/DAC/integrated amp).
