Replacing a Sonos Connect with another Streamer - The digital dilemma!


I currently have a Sonos Connect streaming music to a McIntosh D100 Digital Preamp with a McIntosh MC 2105 Power Amp downstream. I have been displeased with the quality of music coming from the Sonos Connect and thought to purchase a Cambridge Azur 851N or another streamer as a replacement.

 Asides from how beautiful the 851N looks,  the good reviews, and It’s interface,  it is also a preamp.  I'm having a hard time coming to terms with the thought of running music through two pre amps (not sure that makes sense). What do you guys recommend?

 I've got $1000 -2000k to spend on this.
