Well, the first time I heard the Jade II on a different amp - was at London CanJam 2019. I was so curious about how far the headphones could scale - I borrowed some Jade II’s for 15 minutes and I went over to HeadAmp and headed straight for the Blue Hawaii Special Edition. They scaled very well! I could hear the quality of the amp, so enjoyable! I recently heard the Jade II on the Shangri La Jr and the Shangri La Senior - both times the Jade II scaled with the amplification. The Jade II is a great headphone, it would keep its sound signature characteristics but just improve on things.
