The internet is both a blessing and a curse. Everyone does the google to become an expert. It's the time we live in.
Sometimes, I think we don't know what we are missing until we do. What I mean is, we all think our systems sound good. We might not know that if we do X it will sound so much better.
let me explain
My system is all vintage, it sounds wonderful!! Went down the hole that is tweaking. Got some improvements here and there. Then I did a partial recap on my pre-amp, just changed out 12 caps in the sound path. WOW, what a difference, changed everything, had no idea what I was missing!! That lead to a FULL refresh on both pre and power amps. OMFG, HUGE difference! More detail, more dynamics, bigger soundstage, more bass, more mid, more treble. But most of all, the noise floor almost vanished!
Had no idea what people really were talking about when they said inky blacks, or dark sound. Low noise floor. During a soft passage to loud, I literally jump in my chair now. When it's quiet, it's really quiet!!! Now I fully understand what a low noise floor does.
My point is, we don't always fully understand what others are trying to tell us, or what certain things really mean, until we experience them for ourselves. Now, I totally can hear all the background noise, totally miss all the detail on other systems.
