Sadly my 13kg ABM600, although it was def a one-handed carry, was far too much for my worsening back so I had to move it on, my 3kg RM500 being more suitable for my needs nowadays. But I loved the ABM600, def the best amp I think I`ve ever had (I did love my Marshall DBS7400 as well) and agree with your findings @NeonMig, they just effortlessly fill the stage but also don`t over-power anything, they just fit into the right sonic space, glad you`re please with your new amp.
