speakers for small room

I have a small living room. My amp is an Accuphase powering some Harbeth P3ESRs and a KEF KC62 subwoofer. Sounds great for acoustic and jazz. However, I also like big symphonic works and the Harbeths don't cut it for that. I'm looking for something more dynamic and something that can push more air to give me that grand experience of listening to big works. Any recommendations? Assume a budget of $10000.

TIA
