Transport Question

Keep and use your Rotel, particularly since it is new. Unless you are so insecure/misguided that you absolutely must buy a shiny new toy!

Bits are bits. If you accessed your banking data from a different computer would it change? No, of course not! Digital data, whether banking/financial or music, remains inviolate regardless of how many times it is transferred or where it is stored. That is the fundamental premise of Digital. The old Analog ideas do not apply! All transports and servers have to output the same data streams. Only audiophools believe that spending more and more on a transport/streamer gets them better sound quality. You should beware of the anecdotal claims made by the 'golden ears" crowd. Like the eyes fooled by optical illusions, the ears are also fooled - especially by sighted testing/comparisons.

@nonoise : Whether it’s financial data, music data or video data the base form is the binary code. That is why a computer can read an optical disk and store/playback all three. 

 The reason why a cable video stream is often poorer quality than from a player is the common practice of compressing (discarding data) done by the providers. They do this also to music files. That’s why I stick to physical media for music and video.
