Allo BOSS DAC
The popular Allo Boss DAC has two successors the BOSS 2 BOSS 2 and the BOSS 2 Player.
The Allo BOSS combines DAC and Reclocker on one card. With its own clock and a separation of the voltage on 3 channels, this DAC offers a low noise floor and a more precise clocking. Attention: This is the 1.2 version of the BOSS DAC with the additional USB-C port for spearate power supply. You can find further information on this feature at Allo.
The popular Allo Boss DAC has two successors the BOSS 2 BOSS 2 and the BOSS 2 Player.
The BOSS from Allo, based on the PCM5122, is a successful DAC with gold-plated RCA connectors and its own masterclock. By switching to I2S master mode, the Raspberry Pi only sends data to the DAC and leaves the clock entirely to the BOSS with its two high quality NDK crystal oscillators. What makes this DAC so special is the separation of the voltage on 3 channels with different filters. One for the digital side, the second for analog and third for the clocks themselves. This translates to very low noise floor and better clock accuracy.
