I believe the 300 series are the lowest range in the B&W line of speakers. The Kevlar cone in the 601s2 is a bit better than the doped paper cone in the 300 series. If you like the B&W sound I think the 601s2 will be a better choice as it uses the same Kelvar midrange cone driver which is found in the higher line of B&W speakers.
b&w dm303 vs 601 s2
Anyone been able to compare these guys? they would be running off a 30watt per channel rotel ra-930ax, source is a sony sacd player. Mainly listen to jazz classical bluegrass rock blues and acoustic stuff. im 100% sure i want the bw sound, dont know why but they have something i like! the 601 s2 are 270, the dm303 are 225 so are the 601's worth the extra 50? im pretty sure they are very similar, maybe even the exact same tweeter, which is why I need your ears!!! I like the yellow kevlar of the 601's but im really all about the sound!
