I have Pass X250 and ModWright KWA100SE, Pass is sweeter and more transparent in medium frequencies, with symphony orchestra or chamber music it has a better color especially in WoodWinds but for commercial music (bass, drums, guitars etc) it can reach to be too lazy and even boring. The KWA100SE has a lot more grip, a lot more punch and a lot bigger and deeper bass, I can't get rid of either because they are both fantastic each in their own style of music. The speakers I use are Dynaudio C1 Platinum. Greetings.
