What is budget?
Would you consider an integrated amplifier?
Vincent makes a tube/SS hybrid integrated that has a DAC onboard. They also make a hybrid preamp that mates with the SP-332. I have owned a Vincent integrated and it sounded wonderful at the price point. Would sound less clinical, not as dry with more air, than the Rotel gear. Great soundstaging.
Another thought, given that streaming is your main source you might think about getting a DAC to pair with the Node. There are threads on this forum that address that option. If your cd player has digital out the DAC could also serve it.
If you enjoy your B&W speakers keep them. There is much you can do to get more out of them.
