Thanks for your answer! It was very helpful
After some quality time, I can confirm my first impressions. It's so enjoyable, it's on the smooth side of neutral but still very detailed, which makes it very musical too. I have to admit that I rather prefer this kind of sound than an overly sterile, cold and extremely detailed sound.
Found my go to setup for the winter: Ibasso DX90 + Thinksound On1 is a match made in heaven.
