If you’ve been here before you may already know that we enjoy a multi-zone music system based upon the long-abandoned Logitech Media Server and Squeezebox network music players.
Actually, that’s only partly true. We still run LMS, but the Squeezebox hardware has gradually been replaced with a fleet of Raspberry Pi SBCs fitted with HiFi Berry DACs, paired to small, powered audio monitors. The four indoor zones all follow this pattern.
Aged though they may be, we continue to enjoy our little fleet of Logitech Squeezebox music players. Sadly, as they age one common problem is the failure of the analog outputs.
The analog output has an electrolytic capacitor on each channel. As they age they dramatically change their electrical behavior. In our case the output level of one or both channels falls off dramatically. This fault has now befallen three of our five SB3s.
The faulty analog outputs can be overcome is a few ways. One of the easiest, albeit not the cheapest, is to leverage on of the digital outputs, adding an external digital-to-analog convertor (in audio-geek-speak, an external DAC.)
Late last year I found a Shiit Audio Modi 2 Uber DAC under the Christmas tree. This little box is not especially expensive, yet seems well regarded. It’s derived from the very well-regarded* Bifrost model, which is considerably more expensive.
