I'm in the process of auditioning a bunch of floorstanders and will probably buy a pair sometime in the next two months. I had the pleasure of listening to the RS6 on Friday and was quite impressed. They weren't mind-blowing in any one area, but I loved the overall sound coming from the RS6. The Monitor Audios were very involving & really got me "into" the music...all genres sounded nice and smooth. I listened to the Mordaunt-Short Mezzo 6 in the same room and wasn't impressed at all...the RS6 was a much, much better speaker (and much less expensive, too).
So far I've listened to the following speakers: KEF IQ7, KEF XQ30, Totem Staff, PSB T55, Mordaunt-Short Mezzo 6 & Monitor Audio RS6. I'd have to say that none of the speakers compare the the KEF XQ30. If I had the money to buy the XQ30 it would already be in my living room (loved them). That said, the Monitor Audios are the definite front runner among the others I've listened to so far. Up next: Epos M12i & M16i, Revel Concerta F12, Dali Ikon 6, B&W 683 & DM603 S3.
