I've read great reviews on the Yamaha DXR10s. Has anyone done a comparison with these and the Altos? I'm wondering if it would be a significant upgrade in sound? I'm currently using the Alto 110s with my Helix. My band recently got some of the Alto 212s for our P.A. mains to use on the rare gigs where we need to supply our own sound. I feel like the Helix sounds slightly better through the 212s, so now I'm thinking about upgrading my personal speakers. It would also allow me to dedicate the 110s for vocal monitor use for the entire band.
