The same could be said about a large number of High End Audio brands.. From the top of my head I could cite Audio Research and Jadis.. Of course this is based on anecdotes, like your evidences
You may believe that you can hear the differences.. You will in most cases, not, ... once a few bias-inducing inputs, are removed.. One of these is the SPL level, thus such comparisons require level matching , the other one is the knowledge of what you are listening to. With these two controls (there are others, but these 2 will be enough IMO), in place, your up-to-then, unusually discerning, hearing will fail you. As it has for so many... This will be humbling at first then liberating. Like knowing that an Apple dongle is likely to sound to you, and 99.9999% of the World population, the same, when level -matched and the knowledge of the DUT removed... to a $!5,000.oo DAC, perhaps the vaunted $100,000 dCS stack ... At times the enthusiasm seems to come as aggression but .. it is so: DACS are a solved problem.. Speakers and especially speakers in most, any rooms, are not. Focus on those, .. You will be glad you did

Believe it..
