Airplay vs. BlueTooth vs. ?

Recommended Posts

Hello all - forgive what is probably a question that has been asked before, but for some reason a search did not turn up anything. I want to incorporate streaming audio into my living room stereo set up and I have some questions, the most basic of which boils down to what is better in terms of streaming for sound quality, AirPlay or BlueTooth.


I want to stream music from my iMac using Fidelia (both lossy and lossless files) into my NuPrime IDA-8 amplifier and then into my Focal Aria 926 floor standing speakers.


The NuPrime is an amazing little beast and has a built-in DAC and BlueTooth. At this point even streaming AAC from my iPhone via BT sounds great. But I wonder if it can sound better :-).


The way I see it, because of other variables, I have two choices. One is to stream music via AirPlay from my iMac to Apple TV and connect the Apple TV to the amp via optical audio cable. I understand that it causes some sound degradation?


The other is to stream music via BlueTooth, for which I would need to get a range extender, because my iMac is in the bedroom and the stereo system is in the living room.


The third way is to get a wi-fi dongle for the amp but that would remove the BlueTooth dongle. Which could be fine. I cannot use the RCA inputs on the amp, as my CD player is hooked into that. Here is a list of inputs on the receiver.



  • 1 x USB PCM / DSD Digital (PCM up to 384kHz & DSD up to DSD256 )
  • 1 x Coaxial Digital S/PDIF (PCM up to 192K supporting DoP format DSD64)
  • 1 x Optical Digital S/PDIF (PCM up to 192K supporting DoP format DSD64)
  • 1 x Bluetooth or WiFi receiver module (optional).
  • 1 x Analog Stereo RCA (analog input will be digitized)

If there is something else I am missing, I am all ears. Ideally, would like the set up to be as simple as possible without audible degradation of sound quality.

...in my opinion / experience...

While I agree "Everything may matter" working out what actually affects the sound is a trickier thing.

And I agree "Trust your ears" but equally don't allow them to fool you - trust them with a bit of skepticism.

keep your mind open... But mind your brain doesn't fall out.

Thank you. I saw the Chromecast recs, but would it be any advantage of it over my old Apple TV - I can only connect through the optical cable, as my RCA inputs are taken up by the CD player.
