I purchased RS6 with matching center for my HT room, wating for them to arrive as dealer ran out of their stock. I like the Monitor Audio sound, and everytime I hear them at someones else's house or at the dealer I get more convinced that they are one of the best speakers at their price point.
OTOH, my brother, with equal budget, auditioned with me and purchased the same week I did, but he went with PSB Image Series. He liked them better, plus found them at a deep discount.
So, as you can see, it comes down to hearing them, comparing, and deciding what sounds better to you. Personally, I highly recommend them.
