Agree with you speaker experience is amazing. For most though practical wise, headphones the way to go. (Space, cost, dedicated room, room layout etc.)Headphones are nice since it removes the room. And more pragmatically, can be used late at night w/o waking up the kids or neighbors.
It can never replace the speaker experience though.
I also think the Susvara is better than Abyss but I can see why someone would like Abyss.
With that said the amount I spent on my headphone rig can probably buy a decent tier speaker system and dedicated room but at the expense of a very very unhappy wife as my living room will be boxed up. Lol!
I was blasting my speakers today (now once in a blue moon occasion) and the bass and the feeling of speakers always still wow me.
