The HS80Ms are the best bang for my buck. I use these for all types of music and sfx. I produce trip, hip hop, classical, rock, world and folk as well as experimental. The big band productions really sound great on these as well. There's nothing I can compare these Yamies to. I've tried the Mackies 8" and they're the closest sounding (for about twice the price!)
. All our mixes sound great on other systems when mixed and mastered with the HS80Ms.
BTW, We don't track/mix/master with subs.
My 2 cents.
