System Empire is definitely a bass heavy tune. I compared the Elysium to the 64 Audio Fourte (which has a DD driver for strong bass) on this track. As expected the Elysium cannot keep up with the bass impact of the Fourte. The Fourte hits harder and with more depth. That being said the Elysium does do a good job and you will hear the bass, and the impact but in a much lighter presentation. Switching from the Fourte to the Elysium, its presentation seems way too light. However as you listen its brighter mid-centric presentation is also good. But it will not shake you as the Fourte can on this track. Now you might like the added clarity the Elysium provides where the Fourte is much deeper overall and has less air. The Fourte might also sound a touch muddy as compared to the Elysium, but you are hearing bass just not present on the Elysium. I think the VE-8 (which I have sent back for repairs at the moment) would be the best choice here. I would expect it to have the bass and the clarity. If this is the music you mostly listen to, I would definitely suggest you listen to the Elysium somehow before purchasing. It may not have a powerful enough bass presentation for you. On well recorded jazz albums, the bass is excellent (Holly Coles's "Don't Smoke In Bed" for example), but this music is much different. Its great stuff, but the Elysium would not be my first choice to use to listen to it.
That being said, on the track AWOL by OPIUO, I much preferred the Elysium. On this track it had a brighter more open presentation and the had the bass and especially the impact as well. It really sounded much better on the Elysium. I think it depends on how deep the bass is. And the vocals were much better. Listening to this, maybe it would be fine for you. On Sun Daddy I went back and forth a bit. The Elysium has strong bass here, but not as impactful as on the Fourte. However, its more open and clearer presentation is also excellent. I feel you will need to find a way to listen to it first. I have a suspicion you will enjoy it after hearing these last two tracks, but I am hesitant to just say go get one, especially at its price point. Hopefully this helped a little. Maybe someone else can also listen and provide their thoughts. Tks.
