Well, we have a new exciting firmware, for some, and for others it is less exciting.
What can cause this?
-equipment differences
-room acoustics
-personal preference
-faulty installation?
- what music we use for comparison.
probably the one we can control the easiest is the latter.
In saying this, Perhaps some tracks sound better on a particular version?
If a NEW version somehow exposes deficiencies in a recording that were less audible with a previous version then our impressions could be deceiving.
I have a “test playlist” of tracks that I have used since the MKII upgrade tests. I put it on and usually in the first minute I have an opinion. This sometimes changes as I let the entire playlist play and see if it beckons me to come sit in my optimal listening chair for a while. Too slow and I get bored, too fast and dynamic and my ears bleed.
MMMMM sometimes the 3rd Bowl tastes “just right”.
What process works for you?
Simply listening to whatever music I am interested in hearing at the moment and paying no attention to the equipment whatsoever. If it sounds better, it is better.
I leave the agonized OCD testing to others.
