Raspberry Pi 4 looks interesting.

Both GPIO and usb improved throughput may have a positive impact on DSD and high rate PCM for i2s and USB attached dacs.

Pi4 as the LMS server and other Pi2-3s as players ?

The CPU is different. So in theory it'll benefit as a player too.  I was more thanking of an AIO (Server+Client).

But now that you mention it, a 2 Pi setup might be benefitial. Combinations include:

• Pi4 Server → Wifi → Pi 4 client
  
• Wifi → Pi4 Server → dedicated cable → Pi4 Client
  
• cable → Pi4 Server → USB ethernet → Pi4 Client
  
• USB ethernet → Pi4 Server → dedicated network → Pi4 Client
  
• cable → Superpower PC (e.g. Ryzen) → dedicated network → Pi4 Client
  

Last time I worked on these mini computers, Wifi seems to affect the SQ. So the first might be out, but it's worth re-testing this again.

Honestly havn't feel so hyped up in a wihle...
