I've got the Aguilar DB680 and the Warwick Quadruplet.
I wouldn't describe the Aguilar as ballsy. Thick, warm, rich, smooth, clean and big, with a very powerful EQ section.
The Warwick is not as thick or big as the Aguilar (in terms of sound) but it has a power amp valve on a dummy load in the circuit to give you the sound of power amp distortion. Different settings bring the power amp valve in and out of the circuit. It sounds fantastic clean or distorted (or somewhere in between).
