Since 2014, I have been designing and building tube amplifiers and passive boxes again, music reproduction is the common thread through my life. I am retired and of course I now have the time
The only thing I was missing was a “preamplifier” containing an internet radio (over WIFI or LAN) and music from a NAS, CD player and USB connection to play music from a stick.
Last week I saw that my son had provided the EL34 amplifier, which he had received from me, with a network music player on which he had installed Volumio.
Further investigation revealed that it was a Raspberry Pi 4b with a BOSS I2S DAC V 1.2.
For about half that price, I can also put that together myself: Raspberry Pi 4 B, 4x 1.5 GHz, 2 GB RAM + Raspberry Pi Shield - HiFiBerry DAC + RCA, the standard 5.1V / 3A prescribed as power supply.
In several articles I have become a lot wiser about Volumio: most desires are fulfilled, including the integration of Spotify.
The only question I still have is: can I play music via USB from the RPi with an external CD player from, for example, a laptop?
Same question for my DUAL turntable with a USB port (for ripping music).
In the future I can still equip this with a 7 “touchscreen, built into a housing” SmartiPi Touch 2 “+” SmartiPi Touch 2 back cover - 35mm ".
