Dwarf cultural armor for paladin

[MikeXG]

Hey all, I have a paladin in the mid 40s who has decent gear, it is mostly the dwarf cultural armor, a mix of enchanted/imbued(str sta wis) and just enchanted(str sta)

The AC is decent and the stats are pretty good - I'm looking into taking his gear to the next level but it seems I'd be spending 2-5k a piece for minor upgrades or I'd need to drop closer to 10k+ a piece. Is the dwarf cultural armor good into the mid 50s or should I start trying to swap the lesser pieces out now?
