Proac Original Response 2 VS Response 3

I own the original Response 2 and using the R2 Target stands. For the $ I put out for these British Classic Monitors I'm very happy but they do seem a bit thin and harsh/forward at times. Has anyone experienced this.

I have found a pair of Response 3 has anyone compared them..can the 3's image like the little brothers and give you the bottom end. I guess you can't have the best of both worlds unless you spend some serious bucks. Just wondering if it's worth the upgrade.
