I remember some 25 years ago I had a Bryston pre/power - ATC 35 combo and complained about the lack of bass. Which was ridiculous really, since on paper that combo was able to produce a thunderous bass ( just like the OP setup). I even went to the dealer, he quickly put together the same amp and speakers and it produced a monstrous bass. I felt so stupid. But in my room subjectively there was no proper bass.
I measured the freq. response, and the reason was a strong room mode around 120 Hz at the listening position even at a moderate level, which masked the deeper bass.
I couldn’t move the speakers around much, so added a TacT Room Correction box and flattened that mode. Immediately I got a flat, deep, powerful bass and as a bonus - a much more natural midrange.
You may have something similar. Start with moving the speakers a bit and walking around the room while listening to the bass. Is the upper/mid bass changing dramatically? Can you find a listening position where the deeper bass goes low and you can feel it properly?
If that’s the case, you may need some extensive room treatment, which is a lot of work, or some digital eq like Lyngdorf Room Perfect which is not cheap, or a new speakers/ amp combo that will behave differently in that region. Probably some good 2-way standmounts.
When I was starting, I had that Idea of a big speaker that will give me a big bass. The reality proved to be a bit more complicated. The subjectively flattest and deepest bass in my room, not using digital room correction, came from a relatively compact quarter-pipe standmound.
