depends on your definition....i am certainly not a "groupie", but i actually do find it refreshing to find people exist on the total opposite of the spectrum where people on the "other site" seem to believe that everything matters even to the point of building $3K computers to squeeze supposed "wow" moments. To be honest, i have a hard time believing either side, and believe the truth lies somewhere in the middle but much closer to this side than the other side. I will "never" start using the word "we" though like seems so popular here..... At least the other side has cleaned up their act a lot regarding mature responses.
You can check it for yourself.
You need a voltmeter to make sure the levels are the same and somebody to change the source/DAC whilst you aren't watching and see if you still hear a difference.
I thought I would but didn't. I have spent well over a hundred grand on hifi too.
I do hear differences between microphones and microphone position (when recording), speakers, speaker location and headphones but DACs no.
That is me, what I recommend is you do a level matched test yourself with instant switching, informal listening ends up confusing the issue.
It is easy to get swept along by the "everything makes a difference" bunch but is the difference at audible level? IMHO no.
If I play pink noise at -15dB and adjust the volume to my normal listening level then play pink noise at -75dB it is very, very quiet. I can not imagine being able to hear something at -75dB added to music at normal level.
