Super interesting and thank you for sharing your experience. I am one of the (probably) few people out there using an RPi with Max2Play to deliver music to my Linn system – setup:
Raspberry Pi 4B 4GB
iFi iPower 5V Power Supply (yes it works despite 5V)
Max2Play (Beta) Buster Image 2.52
Logitech Media Server 7.9.2
UPnP/DLNA Bridge Plugin *
… wireless connection to …
- NAS with FLAC/MP3/Playlists
- Linn Majik DSM/2 * via UPnP/DLNA Bridge Plugin
The Pi has no dedicated sound card HAT installed, and serves purely as a streamer/transport to the Linn.
Given your experience, I am obviously keen to try out an RPi 4 8GB.
I am wondering, are you using LMS to transcode your music before sending it on its way to the players? If yes, could the transcoding step be where the additional RAM and increased performance make a difference?
