I like Markbass gear but for me it’s far more suited to “warmer” basses such as Precisions. I also find their cabs to have a high end roll off as well - get a sound from a Markbass amp into a Markbass cab, DI that sound and it’s much toppier/treblier through the PA.
We’re all likely to recommend what we use ourselves, and I’m no different, Ashdown, however their top man Mark used to work at Trace so there’s a connection to the gear that you loved there. Their RM cabs are plenty light enough, pair them with one of their ABM amps which again are light enough, but which aren’t class D, they have real punch and depth to the sound, and you’d have a rig that would probably fit much better with what you’re after.
