Not exactly, at least not the way I have it configured. Its fundamental purpose is to discreetly break out and FIFO (first in first out) re-clock a digital audio signal using dedicated hardware with ultra low phase noise SC cut crystal oscillators on dedicated ultra low noise PSU rails, galvanically isolated from the incoming signal chain, and separately shielded in a faraday cage (actually multiple cages for the mains/FIFO/compute sections of the chassis). The remediated digital signal is then sent to my DAC (digital to analogue) converter via I2S (inter IC sound) which is originally a protocol used board to board inside let's say a CD player. In other words it takes various digital music streaming sources and cleans it up to where it meets / beats a dedicated CD transport in audio quality.
But on top of the above core functionality you can see I've given it a touch screen based frontend which is running on Raspberry Pi Lite OS with internet access and also running a music streaming server (Lyrion). Lyrion has many capabilities, NAS indexing and streaming being one of them. But, my current use case isn't NAS - rather it's to stream from Qobuz, Tidal, etc with lossless ultra low jitter and ultra low noise input to my DAC.
The hardware is not only state of the art in componentry and function but is modular and modifiable (e.g. I chose to upgrade PSU rails with ultracapacitor filtration, I chose top of the line SC cut crystal oscillators, and I could add optical and spdif output via GPIO expansion), and obviously the OS and software are configurable to nearly anything so I have a true gem on my hands IMO. Maybe I'll acquire a library of music files and start NAS streaming...
. Well done.
Also case in point why I can really get behind a good CPK
