There are many things involved and audio jitter easily can make the
sound muddy. I never had an audio card mounted to my computers, that did
reach the sound quality of my consumer HiFi equipment, so I suspect
there's simply jitter making the sound less transparent.
I suspect that without audio jitter the sound quality of a RME card
should at least reach the sound quality of a Sony consumer DAT recorder,
but I doubt that on my machine the RME card does sound as good as the
DAT recorders I own.
Assumed people make digital copies, than it's still the question if they
really make a copy or if they mix sound, don't take care about jack
issues etc., I experienced more sound loss for "digital copies" using
jack, than for even cheap analog gear.
It always depends to the usage. Regarding to the workflow inaudible
rounding errors etc. might become audible and who's aware that there
could be issues looping a signal from the output of an app to it's
input, if you don't take care about the order of the ports.
However, back to the topic, I suspect that audio jitter is caused by a
combination of chip sets and kernel versions.
A lot of issues aren't esoteric. I guess that even many audiophiles
aren't idiots, they don't pay 1000,- € for a cable, to get better sound,
they pay for the optical design, to get an unique status symbol etc.,
some people simply have enough money, for some people 10000,- € are less
than 1 Cent is for you and me. They don't have the time to become audio
experts, audiophiles are consumers, not interested to get the same
knowledge most of us have got. They don't need it. My dentist is an
audiophile, he has got knowledge about dental medicine and I only expect
knowledge about dental medicine, not about audio.
"On a serious note, people seriously believe a real-time kernel sounds
better than normal kernels."
Using a kernel-rt I get less xruns, so it's not impossible that it will
increase the sound quality, even when I'm unable to hear an improvement,
the better sound quality is visually reported by the counted xruns.
Seldom 2 computers are equal, nearly everybody of us has got another
machine, so issues are likely and less likely esoteric.
