Was with you for a moment but ... Even in palatial room Wilson Audio towers would not be an option for me. There are objectively better for much less money. If you aske me and those who know .It depends entirely on the room the speakers will be in and the specific needs being addressed. I'm in a small enough room that Wilson Audio towers will not be an option. It's gonna be desktop audio. If I want full range there's gonna be a sub. No point in too much power. Lots of absorbent materials in the room, so additional acoustic materials would probably be a waste of money. I could spend more than the $20 I spent for the speakers and $50 for the sub, but any move would be lateral: different, but not necessarily better. $50 for the AVR, $140 for the DAC, about the same for the headphone amp that doubles as a line level pre/DAC link to the AVR. Think I'll stand pat.
I believe it is room /environment dependent. Not music genre dependent. There is a school of thoughts that assigns music genres to frequency range. I do not subscribe to this. You will find the entire audible spectrum in most musical genres.e.g. It is quite an en experience to listen to a solo barytone on a full range system ... Accurate Audio reproduction has its own set of requirements that include:
Sufficient SPL within the listening volume/space
Smooth and extended frequency response from say 50 to 15,000
Distortion that remains under audibility at realistic SPL and within the frequency spectrum.
There are other among these smooth directivity or at the very least, Controlled Directivity.
Another thing is the level of expertise of the audiophile and/or the amount of work/effort he's willing to put in setting up the system. And this moves the goalpost. Some will get excellent result with a pair of Genelec + SVS subs + DSP/EQ.. other may be more at ease with something like GLM, thus Genelec subwoofers or other semi-automatic DRC/DSP/EQ. Some are willing to pay for convenience, some know enough not to .
I would say that $12 K these days is the point of diminishing return for a full range speaker system: pair + subs+ DSP/EQ., in most rooms this side of a 30 square meters room with 3 meters ceiling.. (320 square feet with 10 feet ceiling)
I hasten to add that it doesn't mean that one has to spend that much for an accurate audio system. Simply that past that amount....
