Probably the best solid state match to WB is gryphon. Altough I am not familiar with DM100, but the warmer sound of gryphons are complementing well the rather cool sound of WB. Still, I think WB is an overhyped loudspeaker. It is a typical modern nice and room friendly speaker, with nice imaging and fairly detailed sound. It is designed not to be sharp at top, so your ears wont be bleeding. That is nice, and makes it very musical. None the less, rolled off highs also means that they lack somehow transient attack. Nice if you like romanticised music, but not when you are want to heat violins biting. But this is a smaller problem, and even you may like it. Its biggest shortcoming is that its small woofers unable provide bass foundation and body for music. Ultimately, they are disappointment because of this. WBs are expensive compared to their flaws.
