Logitech Squeezebox 3 vs PiCorePlayer on Raspberry Pi 3B+

Long, long ago, in the earliest days of this blog, I described my DIY approach to a whole house audio system. The strategy centers around a collection of Logitech Squeezebox 3 streaming audio players, each mated to a pair of powered audio monitors. All this worked great until the aging SB3s started to fail. Drying electrolytic capacitors cause arthritis in electronics.

Faced with failing SB3s, and the occasional desire to grow the installation, I resorted to using a most excellent combination of the Raspberry Pi3 B+ single board computer running PiCorePlayer in combination with a HifiBerry DAC. I’ve got HiFiBerry DAC+ where –10 dbm RCA output is suitable and DAC Plus Pro XLR where +4 dbm XLR balanced output is required.

The RPi, HiFiBerry and PiCorePlayer combination work great! They outperform the original SqueezeBox 3 in every way, save the lack of an IR remote control. Also, they cost less, even with the fancy metal case.

All the above is preface to help explain something that I discovered this past weekend. There’s a fundamental difference between the behavior of the SB3 and a RPi/HFB combination.

My First Raspberry Pi Project: Using Hifi Berry DAC to Emulate A Squeezebox

RPI-HB-DACRCA-300pxSome time ago I received a Raspberry Pi B+ as a gift. It had been on my amazon wish list, and for good reason. It looked like one practical approach to emulating the venerable Logitech Squeezebox, which to this day serves as the basis for music playback hereabouts.

Since we were not expanding our music playback scheme there was at first little motivation to got ahead with this effort. That is, until the analog outputs of our existing fleet of Squeezeboxes started to fail. Eventually the analog outputs become unusable, the result of failing electrolytic capacitors. Three of our five SB3s now suffer this malady.

So, not long ago I set to the task of emulating a Squeezebox using a Raspberry Pi 2 Model B, a HiFiBerry DAC and a 4 GB micro-SD memory card. To this core I added a suitable case, a power-over-Ethernet splitter and piCorePlayer. All in, this rig cost under $100.
