I missed a couple days and at least 300 posts so may not be following this exactly and understanding little, as usual.
Inspite of people hearing differently let's imagine a loyal Schiit Hi-Fi enthusiast that's been tinkering at building a 2 channel system.
The HiFi enthusiast has a Freya, 2 Tyrs, a pair of floor standers of reasonable quality readily available speakers well positioned in a reasonably appointed room and a Modius balanced DAC.
The next purchase is a Yggy MIB.
If the enthusiast exclaims, "the Yggy sounds better! The instruments sound better. I can pick them out better on my favorite tunes than with the Modius". Was the individual "interacting" possibly or primarily with the fact that it's a new purchase, and it's a Yggy? Next, a quirk of the randomness of the universe, 100 loyal Schiitheads stop by one by one for a listen, they're told Yggy has 100 hours of play time, they all sit in the same position, just the individual, not a room full of loyal Schiitheads to change up reflections, and they compare the Yggy to the Modius and they all say "yes, I like the Yggy better it sounds 'gooder'!
The music just sounds more good!"
Are they hearing or "interacting" the same because they want to hear or "interact" that way because it's a Yggy?
If individuals buy new gear, replace a speaker element or roll in some new tubes and they enjoy their music more seems like a win for the individual whatever the truth of the matter.
...soundstage is irrelevant.
Ok point taken. In Jason latest chapter he reported that the new Aegir "slaughters" the old Aegir, and that not one person preferred the old Aegir.
It sounds convincing. I only know the results of what Jason reported. I believe him. I have ok amps and much better sounding amps and have experienced that kind of thing. But it's only for me and me alone? Factoring out the hyperbole, in proper "evaluation" technique what "evaluations" would you use to validate the superiority of one amp over another.
In that regard what is the proper way to "evaluate systems". How does one properly go about it? Or any other equipment. How many on this thread know the proper way? And, for instance, can filter out "soundstage", whatever that is, out of the equation for proper "evaluation". I surely do not but am genuinely curious as to what it is.
