Yamaha vs Rotel

Yamaha will have best build (and probably parts) quality by far and will have a warmer, fuller and more robust sound.  I’d put the Cambridge and Rotel more in the “white wine” sonic category, and both have had their share of reliability problems with Cambridge probably being the worst just going by the number of people here who’ve had problems with their gear.  Personally I’d take Rotel over Cambridge generally speaking for both build quality and sonics FWIW.  Hope that helps. 

I think pretty much any streamer/DAC combo will be a step below your system, even going used.  If you’re up for it, I think something like a raspberry pi streamer with a Gustard A18 DAC would give you better performance than an integrated unit at this price level.  It also gives you greater flexibility to upgrade one or the other as tech evolves.  Anyway, that’s what I’d do FWIW, and best of luck in whatever you decide. 

I’d think the Yammy would be a little warmer sounding just going by reviews, and way ahead in the looks department IMHO.  Congrats on winning the longest screen name award btw.
