"A speaker with an airy treble, warm midrange, punhy midbass and that goes very deep". wipe spendor speakers of your list then, my last pair was boring.
I own neat motive 2 and without doubt the best speakers I've ever owned. they can be bright if they don't like where there positioned. I recently moved in to my new place, divorce no furnture so the hi fi was being positioned first. . room about 17x10 they sounded horrible along the room, bright and lost all the naim mids, now pointing width ways (10ft) only 4 foot apart and in a alcove they was back to what I purchased, its like they almost love be positioned badly!
