People making generalization miss always the point...
You cannot know what my modified K340 can do...
When i listened them with organ music from Bach by Marie Claire alain for example, i hear the church acoustic OUT OF MY HEAD, as if i was there... i felt the higher bass in my chest not in my ears... And i felt the bass notes till 20 hertz in my feet by bones resonance... The first time i even was so surprized i jump on my chair ...Bwaaaahahaha...
As usual with many audiophiles they bash others experience to promote their favorite fad fetish gear pieces as the ONLY solution... In your case subs grid...
You dont seems to be an exception to this rule...
And you are so oblivious of others needs that you cannot imagine that some own now a small acoustic room with no real need for many subs or even one for many other reasons too ....
Then in your ignorance you decreed that with no subs no system could be audiophile perceived experience...
Pathetically childish ...
Bwaaaahahaha...
Headphones can sound good because they can cut the room’s confoundance out. But, they are very restricted. You can’t feel the music in the entirety of your physicality with headphones (ear huggers), like you can with a hifi system.
If you’re running a pair of speakers without a sub, you are missing entire lower octaves of music contained in some of your recordings. No matter what acoustical interventions and positional eq’ing you may have done, it is highly unlikely that you’re fully addressing room modes and so on without deploying subs. The acoustical satisfaction is sliding down a bit there, in light of all the above mentioned. 😁
What you just described is consumerism in audiophile products...
I had nothing against that.,..
But use your brain and think about others people looking for their own solution without this cycle of upgrades...
My cycle is learning how to install acoustically optimally and mechanically optimally and electrically optimally with my own devices what i already have if synergy was reach...
Bwaaaahahaha...
Later on, if i find some high end again that’s mind blowing, i’ll buy it and then i’ll beat it over time with the lower priced gear (as things improve), get my money back, etc. That’s the cycle i operate on.
