$1500 bookshelf speakers with laid-back highs?

Hi all,

I currently have the Monitor Audio Gold GR series 5.1 system. I like a lot about it, but to me, the highs are a touch too bright. I am looking for something a little smoother, even if it means the highs are rolled off.

If anyone is familiar with the Sennheiser HD650 headphones, that is the sound I am looking for.

Thanks
Greg
