Didn't hear Dream, but I thought it was neutral, I guess read it somewhere? I only have The Answer, rewired with modular TWau, so I assume it's far away from The Dream. Once I get time for a more critical listening, will compare Xelento and VEGA closely (from the first impression, Xelento has less bass impact and more resolving analytical brighter upper mids in comparison to Vega which has deeper low end and more organic upper mids).
Regarding shell material, I asked my Beyer contact, but didn't hear back yet. I can tell you these are super lightweight so I wouldn't be surprised if they are coated. But keep in mind, the shell material is part of a sound tuning, not just a requirement for TOTLAlso, Xelento uses Tesla transducer where who knows if it's an issue to have an enclosed metal capsule-shell around it. I'm just speculating, but I'm sure Beyer engineers looked at every alternative and if some of their budget iems (like DX160) can utilize a metal shell, I'm sure there is a good reason they went with something else in Xelento, but I don't know for sure about the shell material.
Of course, when I listen to the xelento, I don't get the plasticky sound I often hear with many plastic IEMs. I Guess It's just a bit of a disappointment, with customs I get the use of plastic and acrylic, but with universals, most premium Flagship universals are metal, and I just would wish to see premium materials being used, that is all.
What I actually did was I compared the xelento and the vega with the same mmcx cable, and with that, I did not find the xelento to be more resolving whether on stock cable or with the same mmcx cable. The xelento did however have a signature that makes details more apparent, but in terms of actual resolving of details and texturing, I did not find the xelento to be better. What I did find was that it was noticeably less dynamic and impactful. As with anything audio, preferences are subjective, and as some have stated they prefer the sound of the xelento over the vega.
I'm any case. Do keep us updated on the shell issue

As for the issue about the shell being used to tune the earphone, one of the basic concepts of speaker design is that the chassis should contribute to the sound as little as possible. I've tinkered with many IEMs and I've found that with plastic IEM, adding chassis dampening almost always improves the sound while with metal IEMs the effect is often minimal. Thus it can be inferred that a plastic chassis generally has much more unwanted resonances than a metal one from my experience, and this is one of the main reasons I would prefer to see a metal chassis in my flagship earphones. Just something I like personally based on my own experiences.
