Caution - N00b Question: Need an opinion on 2 channel audio source/amp

I've got the home theater portion of my system set, just need a suggestion on the best way to build out the 2 channel portion.  So far I have a Marantz SR7012, and Goldenear HT speakers.  My fronts are Triton 1's.  The question is:  If I'd like to amplify the Triton 1's separately from the Marantz for HT, but also produce the best quality 2 channel audio for the $, what would you recommend?  I'll mainly be streaming from TIDAL.  I was debating between an NAD C388 with BluOS to stream TIDAL & amplify the front speakers (both for HT & 2 channel), or the Cambridge Audio Azur 851N + 851A.  I'd like to keep the streaming/2 channel amp portion under $3k.  Should just stream from the Marantz and get a 2 channel amp?  Is the DAC on the Marantz or C388 as good as the Cambridge?

Thanks!
