Listening to "Crime of the Century" with comet right now, I struggle to understand why would anyone call this amazing IEM "entry-level". No, I don't think the comet is "entry-level". It just happen to be affordable. The instrument separation and imaging capability of comet is at least on par with my Noble Savanna (which I considered "mid-fi") while the crispness of notes exceed my Noble Sage (also mid-fi). Overall, it is a solid all-rounder with a non-neutral but very enjoyable sound signature and good technicalities. I think comet is within the tier of "solid mid-fi" despite its' sub-200 dollars price.
