ALLO Isolator v1.2 .... Is it needed?

[STUDI]

In my opinion this is unnecessary if the DAC has its own low jitter level generators. Isolator or reclocker is only helpful when the source of DAC timing are clocks from the Raspberry Pi processor. A debatable case will be when DAC timing is obtained through PLL synthesis as long as it is synchronized to the I2S signal. As a cons, it can only be unnecessary expenditure and unnecessary additional electricity consumption.
