LS50 Wireless connection preference?

What media software and streaming service do you use?

The Node/Aries/Toslink combo sounds like it could be your best option.  This way you can stay away from excessive “DA/AD/DA” conversion.  Sometimes we can take one step forward and two steps back if we don’t pay attention to connections/processing.

Older MacBook Pros have a mini-Toslink output, but that doesn’t help with your MacBook Air.  You could get an AirPort Express, which is currently being discontinued, but it only supports 16/44 (not sure this is a limit for you) and only works with AirPlay.  I’m eager to try an AirPort Express with an Empirical Syncro-Mesh.

The other economical option is using a Chromecast Audio and use its optical output. It sounds real good if fed into a good (external) DAC and allows for streaming content from various cloud services like Tidal, Spotify, etc. It sounds almost as good as my Bluesound Node2 when fed through the same DAC.

Thanks for the replies everyone,

Since I posted this thread, I picked up a Node 2 and am going to go analog w/Kimber Silver Streak (had leftover from earlier) so I can still have MQA capability. I guess the Node’s DACs should work out well. Now I need to figure out how to add a turntable if I want later. I'll have an optical and USB input left on the KEFs to use.

Congratulations. Node2's DAC is quite good. The BlueOS app is also very user friendly. Let us know how you like it. 
Enjoy.
