I am about to purchase a Cambridge CXA81 to replace my NAD C326BEE which has a bunch of digital inputs and a seemingly respectable built in DAC. It also has a USB audio input. With the upgraded amp, I was thinking about upgraded methods of streaming.
Currently my streaming is usually done with a relatively cheap USB adapter from my phone and into RCA inputs into the NAD amp. Occasionally I will plug my MacBook in using a phono-RCA adapter. Usually sounds decent enough for the purposes of background music.
Here are three ideas I had:
1. iPad/iPhone using Airplay to 3rd gen Apple TV through optical output to CXA81
2. iPad/iPhone with USB adapter to the USB audio port of the CXA81
3. ChromeCast Audio through optical out to CXA81 (would need to buy the CCA)
Would all of these equally provide a high quality option that would improve on my current bluetooth option? If I were running Tidal/Qobuz or some equivalent on all of these devices, would one provide a preferable signal to the others?
Thanks for the input.
