Thanks everyone for replies. As for listening sources, I’m listening mostly to Tidal lossless quality music. And also I have my own collection of FLAC files in HDD connected to Uniti Atom.
As for listening volume, I mostly listen at about 25-30 volume setting on Atom (I would call it as “average” listening volume. The “max volume” setting is set to 100 in Naim app). And sometimes I like to turn the volume up till about 40-45 and I would call it “pretty loud”.
But I do not turn up the volume till 45-45 listening rock and metal, because it becomes unpleasant to my ears. Ok, I know that it also depends on recordings. But let’s take Bon Jovi (album “Crush”), Bryan Adams (album “11”) and Metallica (album “Death Magnetic”) as examples. These albums sound not good in my system. If I turn the volume up, highs and mids become unpleasant, because there is not enough bass compensation.
I know, that turning the volume up makes bass perception better and we begin to hear lower notes better, but this do not help. Music is unpleasant, harsh, and “thin”.
I also thought that it could be room acoustics problem (as Bystander also recommended). I have REW software and measuring microphone and checked frequency response in listening position. The measurement is here:
The graphic is far from linear, but besides that seems there is plenty of bass (though much bass is created from modal ringing as waterfall shows). However there is a slope down at about 50Hz which makes me worry. Maybe rock and metal bass is mostly located in 35-45Hz region (bass guitars are widely used here). This would explain why electronic music sounds good. Maybe the main bass line here is located somewhere between 50-60hz…?
As for room size, my speakers are located in small space 4mx3.5m, BUT there is no left wall – it opens to larger space connected with kitchen. The whole flat size is 56 sq m and it is divided with drywalls (single layer with rockwool between layers). So I don’t know should we count drywalls or not, as they pass low frequencies below 100hz. This is my living space:
And maybe here is another problem. but I’m not sure. Drywall passes low frequencies below 100 hz to another room, while reflects frequencies above 100Hz. So maybe this creates a frequency mess which is very noticeable in rock and metal. High frequencies are “ringing” between drywalls in smaller space, while low frequencies are “ringing” in much larger space, because they do not “see” drywalls.
I was thinking to reverse speaker placement – place them to concrete wall and see if it helps. But didn’t do it yet.
