“Wow” factor can take on different forms: abundant detail, dynamics, visceral slam, seductive decay, driver/woofer speed, air up there in the higher frequencies, massive soundstage, pinpoint imaging, feeling like “you are there” at the performance. Fulla 2 is good for its intended use case, but it sounds like you are wanting to advance things.
Some possible cans based on the info you provided: ZMF Aeolus with Universe or Verite pads, Focal Clear. There are sometimes open-box, B-stock, or used deals to be had.
I have an Asgard 3 and it’s a great all-around solid state amp. However, your favored music might benefit slightly from a more energetic and detailed presentation. It would be important to thoughtfully pair the cans and amp. I would add the Schiit Jotunheim and Lyr 3 for consideration. Perhaps choose the (immediate or eventual) cans first before deciding on an amp.
See comparison here:
Possible DACs: Schiit Modi and Modius.
The performance of the Ananda is at a level where if it were me I’d upgrade the electronics first before getting new cans. Enjoy your audio journey.
