The VE8 is inked into my brain after hundreds and hundreds of hours of listening
(Maybe there actually such a thing as listening too much to an IEM...)
You mean compare with the Elysium or Erlkönig ?
The Erlkönig is the closest to the VE8, you can instantly hear it's a sibling (so to speak) - I am talking about reference signature 4 (need more time to go through all of them). There is clearly more sub bass this is one area I always was left wanting for more with the VE8, not so with the Erlkönig sub bass is really great. I would say mids are fuller sounding on the Erlkönig, the VE8 mids to me are fairly neutral - lower mids are leaner. Overall I feel the Erlkönig is thicker sounding, separation is fantastic but not as accentuated as the VE8 it's not as separated. To me the VE8 has more refinement in the upper treble than the Erlkönig (again, signature 4 so there might be a signature where it's less true) but I like the Erlkönig lower treble better, more energy.
The Elysium is quite different from both the VE8 and Erlkönig.
In fact the Elysium is different from anything I have heard, period. The mids are really stunning, the star of the show : they fill out the image and at the same time they seems to contain so many layers (in all direction) and rich details with such an accurate timbre. I feel they are more neutral than the Erlkönig even on signature 4 but also thinner than both VE8 and Erlkönig (but I suspect custom Elysium would be a bit fuller). Separation is fantastic on the Elysium but it's all a "continuum of nuances", if that makes sense. You don't hear any artifical separation. Soundstage in that respect is simply fantastic... it's holographic but in a so very natural way it's eerie. Depth in particular and the layering in that direction is unreal because not used to hear it...
The upper treble clearly benefits from the eStats, with blazing fast transients, superb extension. There is that quality that is so specific to the tech, reminiscent of the KSE1500 I owned with sort of an "ethereal" quality. There are downside to this though, it's almost a bit unreal at times, less live than the VE8 and more like enhanced. I'd still give my vote to the VE8 upper treble which I feel is more realistic. On the flipside the resolution is insanely good and the upper treble performance certainly as impact. I'll mention bass last because I see it as the supporting cast on the Elysium rather than a highlight. The bass is fast, detailed and blends perfectly into the mids. I leans toward a softer attack and a very natural decay. The VE8 has more slam, and the Erlkönig is the master of them all there.
Hmmm, I wouldn't say the Elysium is softer... the mids are very sharp with clear edges to notes but certainly the Erlkönig's mids are more in line with the VE8 mids which are more impactful because they have more body, they sound fuller to me.
I am talking mostly of impressions out of the N6ii with T01 motherboard here. I'd love to test this accross different sources. I ran it shortly with A01, I'll do this again. Both impressions are with their respective stock cables.
