I've auditioned the 805sigs and the N802's in my friends system which consisted of an ML dac/transport, krell pre and aragon palladium mono's(4). Speaker wire was cardas golden cross and the room is 22x16 with 10' ceilings. The 805sigs imaged better, throwing a deep, wide and high soundstage and the N802's had more impact. With the addition of a rel sub we both prefered the 805sigs. Now, he's thinking about selling his N802's and either buying the 801sigs or 805sigs. I originally owned "stock" N805's and was looking to upgrade and listened to speakers from about a dosen different manufacturers including the new B&W 704's. When I heard the 805sigs I was blown away and this was a speaker that I was not considering. Even my wife, who is not an audiphile, loved them. She said that the sound was good enough to look the other way when it came to the black finish. She hates black speakers. Now I'm hearing things that I never heard before. I've been going through my music, and movie collection, and listening to things that I have not picked up in years.
A few weeks ago, I had another friend over and we were watching a show on TV and he turned to my and said that we must be watching in surround sound because he was hearing things behind him. My reply "this is in two channel stereo!" Then I put on DSOTM while we were talking and every couple of minutes he would stop and ask me to replay a track. He was telling me that he was hearing things in the recording that he had never heard before. Now he's going to spend his tax return on a modest 2 channel rig and a pair of 805sigs. We went over to the local B&W dealer and put down a deposit on a pair last week. BTW his current system consists of a pioneer receiver, sony CDP and a pair of Kef Q55's.
Anyway, I'm rambling on now. Give the 805sigs and listen and judge for your self.
Good Luck,
