As just a “normie” who spends some money on audio, a pox on both your “measurements rule” and the “golden ears” side that dismisses anyone not “trained”..
I buy what is pleasing to me. Don’t give a dang about “measurements” which mainly are measuring that which is beyond audibility for anyone over 40 that has actually had any kind of “blue collar” job.
Can I tell the difference between consumer grade klipsch vs magnepan and tektons? Absolutley. (I have all 3).
Can I tell the difference between an underpowered amplifier and one with sufficient power for the dynamic range of what I listen to and how loudly I listen to it? Yep.
Can I tell that I prefer tube amplification for mids and highs, using SS amps for lows and subs for under 100hz (for music)? Yep.
Can I tell the difference between a 192/24 vs mp3, especially as volume increases? Definitely.
Can I tell that I prefer a $2000 tube amp over the same power $20000 tube amp?
Or at least hear no difference..? Yep.
What I buy, and what equipment provides me with hours on end of continued listening enjoyment, at a price point I am willing to pay, has NOTHING to do with some elitist, sneering, snob telling me that I am “wrong” because my equipment doesn’t “measure up” or that my choice is wrong because some “golden ear” says so.
THAT is “my kind” @amir_asr
