Hi.CD, DVD-audio or vinyl, & whatever programme sources are ALL potentially or actually affected by EMI/RFI, mechanical vibration & the like. It's a matter of the interference frequency & magnitude which may be made audible or not.
Given same listenng environment & same mating hardwares, all programme producers, e.g CD or DVD-audio, are subject to the same level of resolution depreciation if any.
Tweaking can something found effective to reduce the harmful audio effects due to those unseen noise invaders.
Even for IDHTs (indirect heated tubes), I put on my homebrew damper onto the tubes of my phonostage & power amp driver stage to kill possible microphonics.
A warning: don't overdamp any tubes. It can damp out liveliness of the music all together. I learnt it the hard way.
