Objective measured findings vs Subjective, time-tested listening help fuel our hobby, often with much howling. Thanks, chayro, in requesting calm on this topic.
As an over-ripened audio guy, I plead guilty to "expected" changes in adding, replacing or removing gear, plus burn-in factors. I've done a ton of A / B comparisons, including assisting cable manufacturer evals, both in-house and in my rooms. Despite this seasoning, there are always unexpected twists and turns. TIDAL updates, for example, can change streaming quality settings, without notice.
There is certainly a place for the Amirs in our hobby. This is the balance. We each possess the most refined listening tools created, however. "Absence of evidence is not evidence of absence." Trust, and utilize laser rulers.
More Peace, Pin
