f917025 what cool aid are you drinking? Do you honestly think that the thousands and thousands of audiophiles accross the world are getting rid of their CD players because their new streamers suck?
We have been at this rodeo for 30 years, and often times when this situation occurs, it is a simple matter of finding out what the issue is, sometimes it is because the older unit is voiced to work better with the system as it is vs the new product which may be more transparent.
Sometimes it is just a burn in warm up issue, a cold dac/ streamer or CD player will take one to two days to come back to sound quality after being unplugged and moved.
Other issues could be that this listener wants a really warm or more rolled off piece of digital where the Ifi DSD pro for example which uses tubes has a fatter more colored sound than the Lumin.
DSD sounds warmer based on the technlogy and how filters are applied, ask most listeners to decribe the sound quality of DSD vs PCM,
We were around when DCS 20 years ago was showing how transcoded PCM files sounded distinctly different than the same file played as a PCM file.
There is also no such thing as basic sound or intrinsic sound quality when a system is an aggregate of all of its parts.
Think of it like cooking, you start with great ingredients, and then add a pinch of salt or pepper or other spices to bring out the flavors you wish.
Most dishes even with great ingredients don't come alive until flavor enchancers are added to the meadly of the other ingredients. If you omit the salt, pepper, vinegar or acidic ingredients, and other similar flavors even the great ingredients fail to capture the palet.
Same thing with a warm beer, same product pretty uninspiring at room temp unless it is a porter or stout, but cool the beer to right temperature and add the right glass and the experience is radically different.
