DAC's : The missing feature: Signal quality


One thing I wish DAC's would provide is some idea of how much jitter and noise a particular input provides. This is something which I think with a little work could be gleaned from the input circuits.

I want something that tells me "woah, that's a really dirty signal coming in, but i"ll do the best I can with it."

One common source of noise is ground loops. Another may be high jitter from a source like Apple TV. This would also help us evaluate the benefits (if any) of various signal cleaners and reclockers.

DAC's isolate jitter maybe they could have something that lets you know how much jitter they isolated from the incoming stream before sent to the reclocker. If it only added $10 or $20 to the cost might be an interesting doodad to watch .
All DAC's attempt to isolate themselves from jitter, ground loop and noise and do so with relatively different levels of success.

I think given the drop in processing power, cost of excellent clocks and DAC chips, maybe this can take over after everyone is done with MQA. :)

Yep,  Source programming and delivery can be a problem with some media.

Right? Like with streaming. Would be nice to know
Jitter detection and then committing to mathematical transforms of measurement is a relatively complicated affair.

Last time I did that, it required the use of an AP SYS2722 measurement system, in a fit of clock designing...

$20k or thereabouts.
