Has anyone tried putting Allo Kali on top of Hifiberry Digi+ Pro?
I know it sounds strange, but even the best reclockers like Ian’s are claimed to sound better with better I2S signal on its input.
I personally noticed that with my dam1021 which also has onboard reclocker, but works better with better I2S signal condition on input.
Technically in terms of noise it also make sense. Since Hifiberry Digi+ Pro I2S signal is created from its own dedicated crystals with its own dedicated regulators then I2S signal generated in such way is much more cleaner than the one straight from RPI. The more clean I2S signal is on Allo Kali the less noise is contaminated into it. The less noise on Allo Kali the less noise passed to DAC. The less noise in the DAC the better the sound, theoretically.
