There is one thing I never talked before. I can't recall when it happened, but I never really got powerful bass with my System 15 (15" dual concentric transducers), thus I got subs to compensate, but even so I did not get much bass.
It happens sometimes though that I listen while the subs are inactive (and the supertweeters stay "covered", as I don't find it easy to adjust their position over the mains). I get the best phase and coherence then.
One day (a few months ago), I thought my subs were active, because I was feeling a lot of good bass vibrations (not as "Boom Boom", simply more present and refined). No change on my part, no nothing, but maybe a change of version in XXHE. I don't recall with what version it occured to me, but I heard this bass coming from the mains and I was quite surprised. I always heard it, but not with that depth.
I never cared for the acoustics of my rooms, I just took what was there. But for the moment, I am not really interested in changing that acoustic, because what I get is always for the better...
And I have to admit that if I was to attempt putting acoustic panels on the wall, I would be banned from my own home !
And there is something I still have to get rid of: this nasty habit of feeling that the HF should be more prominent... This is an heritage of bad speakers listening (and bad digital dacs)... Many centuries ago, when I was recording my LPs on a cassette deck, I used to record with the Dolby ON, but listen with it OFF... I did not care about the tape hiss, since I preferred to have more treble than less...
And this nasty habit got the best of me for decades...
Finally, since I like to hear agressive electric guitar, the edginess and "metallic" feel of digital seemed to suit me better... Because something was lacking in my mind compared to vinyl. Now I understand that it was not the same, because there was always a veil over the CD sound. Not anymore...
So yes, I come from afar...
