The Elysiums do not have iron fist control over the bass, they do however sound “natural”, or “believable”, surprisingly close to real instruments if the recording allows.
They’re not the best match for electronic music, they’re however incredible for real instruments, they do drums really well for example, which sound very believable because it provides one of the most complete renders of all the individual parts of the drum and the room, rendering all resonances with constant and natural decay you can hear bouncing off the virtual walls which define your soundstage.
The Zellatons really excel in that area, they completely disappear and the soundstage extends far beyond the room boundaries. I really do not want to bring subwoofers back into the discussion but this trait is one of the things I valued most from adding subwoofers before, you most definitely don’t need them for this particular aspect.
But for slam / power, I would pick something like for example the CJ ART108s for tubes, or very high quality solid state. But that will leave you craving if you have heard what the Elysiums can do partnered with the Zellatons, beware before you try.
I listen to just about everything except metal and techno.
