There are 4 elements to an excellent streaming setup. The Network, The Streamer, The Music Server, The DAC.
The network, streamer and DAC are the most important in equal measure. Skimp on any of these and you won’t get there.
The music server is a convenience device in my view. Pay more to get easy ripping and nice user interface and easy library management. Pay less if you’re more techie and can do a lot of manual file shifting. My music server is a Raspberry Pi with 2TB drive attached, it’ll sound the same as any other fancy server if you’ve got your other three elements right, in equal measure.
My system:
Network switch, network cables & RFI filtering - £3000
Streamer - £3000
DAC - £3000
Very manual techie Music server - £100
