I find this fascinating (about to be a little off-topic though). I heard the Solaris at CanJam Shanghai and heard NOTHING like what you describe. To me they sounded thick, syrupy, really undefined. I have the Nighthawks, which some people describe as 'veiled' and while I will happily agree that they are far from treble-centric, they are still clear to my ears. The Solaris was a very quick 'no' for me. I have also found the Andromeda to be disappointing, though not as bad as the Solaris. Amazing how very different the experience can be from one person to another and a very clear indicator that other people's opinions are only guidelines - one MUST audition future gear!
The PP8, on the other hand, was love at first...listen. Everything I have looked for in an IEM - definition, balance, soundstage, musicality - all there and then some. I never thought I would spend so much on an IEM. And yet I agree with
@noplsestar - though clearly an investment-level financial commitment when viewed in isolation, when you try to find their equal among other TOTL units, you're hitting much higher prices. For the quality of sound they deliver, they are actually a bargain!
