BOSS Premium (Add-on)

Description

The RPI has one major problem with audio. The clocks coming from CPU can only output one frequency clock perfect (very close), resulting in major problems with audio files sampled at 44Khz (and multiple). Too much jitter on i2s clocks.

BOSS DAC is unique, because of the the design. First the power on 3 channels and filter it further: one for the digital side, the second for analog and third for the clocks themselves. There is a second filter (LDOs) to further quiet the noise. Note that it uses some of the best LDOs on the market (LT3042 from Linear). In addition, Japanese oscillators from NDK for a very low jitter clock - almost as good as famous Crystek.

Finally, on the analog stage there is a film capacitor (not ceramic) for a quiet DC to feed the TI IC (ceramic exhibit some piezo distortion, not what you want in analog stage). Added is also a supercapacitor for an extra kick when analog stage is asking (like deep bass).
