Everyone's entitled to their opinion but it's a little sad to me if a $3000 MSRP IEM isn't somehow considered TOTL. Having heard the Jewel myself I could say it sounds great but I also can't see why it costs $2000 more than the EXT.
It costs $2000 more than EXT because it's being marketed towards people who will pay that. Based on sonic quality alone EXT is most certainly on the same level as both Jewel and Traillii imho, though each IEM has its own individual identity and distinct strengths. If we're being honest TOTL starts at about $1K. Anything beyond that is fine tuning to preferences.
