I’d personally look toward a yggy a2 if you want more of a sidegrade to the exogal as an alternative, but a wavelight if you want an upgrade as I think that pretty closely nails what you are generally after. I do also think that if you could find a used bricasti m1 that would also be pretty sweet overall although it isn’t as strong in depth so that’s mainly the concern I’d have but good in other regards
Stretching budget but imo still reasonable a d1-core would be damn nice, same with a mystique evo (although might lean a bit more warm than you are after, but I think you should still be fine, a v3 could also potentially work)
