Any audiophile use computer (MacBook) as your audio streaming source?

I used a Mac air for years and to my ears it sounded fantastic. I did tried dedicated streamers from the the Eversolo 6, master and 8. I even tried a Hi Rose 130. Not even it was appreciably better. The Aurender N200 got slightly better. It took 12k and a Aurender n20 to get noticeable better. That what I have now feeding my Holo may Kte. 

Re computer vs. streamer, once you get an external DAC, the streamer (with built-in DAC) argument evaporates...IMHO, streamers are utterly overpriced for what they are, and you have to take the DAC that the manufacturer slaps in there. The whole "optimized OS for audio" is marketing hype, considering the minuscule computational power it takes to play/decode/transform audio signals compared to processor power in current computers.

This is absolute garbage advice by someone who clearly has no idea what they’re talking about. Listen to the others here (including me) who’ve transitioned from computers to a dedicated streamer and found a night and day difference. You’ve got your answer.

Streaming music through a computer is yesterday's technology. It is way too noisy. If you get a separate streamer with an adequate ethernet line cleaning method you will know what we are talking about.

Use your noisy MacBook Pro, no problem. I use a noisy crappy computer too. However, you need a moat in front of your DAC so that the analog noise before the moat does not travel up the USB cable into the DAC.

I use the relatively cheap Sonore OpticalRendu. I ignore Ethernet since Fibre cable sounds better to me. Fibre cable is made from glass and cannot carry the analog noise from the gear before the moat. The fibre cable is the moat. 

Getting fibre into you home system can be done for under $100 via a network switch. Sonore has a complete solution for this, though I only use some of it since I already have network switches with fibre support.

If you are a ROON user (RATT protocol), this stuff is easy to do. They also support many other protocols which your Mac likely uses.

If you like a sound stage flat as a pancake use a PC.
