..yeh but fixing them are low hanging fruit easily accomplished in some cases by just following the chip mfg application notes .Perhaps - but I've never ever heard one. Just like jitter is real, and I've never heard that either.
Most of these things are real, in that you can measure them - see them on a scope etc.
None of them are real though as an audible issue that detracts from listening enjoyment.
and cost nothing .
Not a life long quest like hiking by foot to Himalaya to meet some spiritual guru , thats how the audiophile story telling goes
I see it as engineering due diligence .
Sometimes it's actually overdone to get nice numbers in the specs the tolerances for "bad sources" are lower on a modern high performance DAC . In another tread we discus a product .
https://www.audiosciencereview.com/...s/audiophonics-digirescue-snake-oil-or.45138/ that can help with that .
I remember my old Meridian 518DAC it had two levels of signal locking .
With "bad sources" like an aging computer mobo or TV spdiff out it entered a more relaxed "wide mode" jitter probably vent up , but you got sound without dropouts.
