Your requirement is exactly the same as mine. After a lot of trial and error, I've ended up with a Genzler Magellan 800 and 3 Barefaced cab's (a Super Compact Gen 3 and a couple of One10s).
The amp: compact class D with a nice, neutral core sound; 2 switchable channels (clean and driven that can be set at different volume levels); 2 shaping options (modern & vintage) controlled by a contour pot; delivers full power at 4ohms or 2.7ohms for 2 or 3 x 8ohm cabs; and is much more reasonably priced than the other American alternatives.
The cab's: compact/light-weight; highly efficient; 10" drivers have a slightly warmer 'classic' sound than the 12".
I've added a mini board with 2 foot-switches (one switches between the 2 basses I use and the other changes channels on the amp), a tuner and a volume pedal. It's taken me over 50 years to get here but I'm really chuffed with this set-up!
