Cambridge audio AXA85 is an Integrated amplifier and Yamaha RN303D is network receiver. You can access different music streaming services through Yamaha Music Cast app. For CA AXA85 you need to have source like CDP, Network streamer etc. You can compare Yamaha RN602D with CA. Within the budget I may select Yamaha RN803D as this may cost same as CA AXA85. Have not audition both so can't comment on sound quality but both brands are respected in Industry and never disappoint the user. Audition is must with speakers...
