I believe both follows the same design philosophy. In my experience, the bass can be very anemic if you have an amp with high damping factor. The Cubes in general like low damping factor and least or no -ive feedback amps. When these two conditions are met, the Cubes do really sounds very musical. These speakers are ruthlessly revealing and will show every weakness or strength in your system. When I get a new cable or any component that needs break-in, I can't hear the speakers until the cables or components break-in totally. What I am trying to say is every small little things in the chain will matter in how they sound.
