Personal feelings on the IEM: Love love love. I'm not really saying the Aurum is one of the best things you can get around the 1000 euro mark, I'm saying the Aurum is one of the best things money can buy at any price point, and especially so if you enjoy a more forward and aggressive upper treble response which I've come to crave. Stupid technical (might be the most technical IEM I've heard), huge stage, unreal treble, fast and precise bass with some of that DD texture. Midrange can be a touch aggressive at times with albums like Anderson Paak's Malibu, but definitely within the "enjoyable" category still. If you do get one, definitely run it off something warm, the PAW S1 and PAW6000 do well, but the SP2000T is in a category of its own for brighter IEMs. It still isn't SO bright that I need the full tube mode for it - I've run it exclusively on hybrid.
To me the Aurum feels like a "
this is what technical ability can be" statement, sacrificing some musicality in the process, but in its niche, it absolutely slaughters. As I mentioned in the infographic it doesn't quite sound natural, but it has an exceptional ethereal quality (a little reminiscent of the Fourte/Fourte Noir but less weird and quirky)
Welcome to the Thummim / A18S family of excitement Aurum, and I look forward to receiving it as a CIEM in a few weeks!
Disclaimer: The Aurum is stupid difficult to drive. I'm hovering between 90 and 110 volume on my SP2000T
