Can your system be optimized to sound better for classical or non-classical?

My system sounds great with everything because its high resolution.

I too spend a lot of time with classical (or, at least, serious music of any era). For me, the essence is clarity, tonality, and coherence from bass to treble.

Every component in the signal path has a sonic signature, and that most assuredly applies to EQ, regardless of technology or cost. I think that extra processing always gets in the way of serious music. For R&R of course, extra processing is the whole point.

@terry9 , Will you explain what "serious music" is?

@artemus_5  Technically, the term 'classical music' refers to a specific era. It specifically excludes Renaissance, Baroque, Romantic, and other eras. Nevertheless, some wonderfully involving and interesting music was composed at these times, and repays serious attention. I call this 'serious music'.

This includes, but is certainly not limited to, such giants as Tallis, Bach, Wagner. Modern examples of serious music are David Hykes' New Harmonic Choir, Gorecki, and Paert.

This contrasts with Dylan (which I also like), and U2 (which I do not).

Classical is the most demanding genre for a Hi-Fi because of its dynamic range and wide frequency spectrum. During quiet passages you want a jet black background without a hint of hiss but you need the power in reserve for the louder sections. Generally other types of recording have more compression so a bit of background noise could go unnoticed. Also, the range of frequencies (from a pipe organ to a piccolo) is going to need a pretty flat 20Hz-20kHz response to sound natural. Pop / Rock / Electronic music will have been mastered to sound good on a wide range of systems so is likely to be more compressed and have less sub 80Hz content.
So I guess I’m saying that if you have a system that sounds good with classical music then it should sound good with most other genres.
