@jallan +1 Not a fair fight as driver research and improvements march on. I've four pairs of ATC, active and passive, so understand the house sound. Spent plenty of time with the DQ 10s and it was for its time something. Just not now. Definitely a decent wall of sound. Any upgrades will bring them forward, never reaching the destination.
Five drivers are difficult to bring together into a cohesive sound field. Can be done, just not with that design from that era.
