1st speaker considerations: Odyssey Lorelei, Meadowlark Shearwater, Spatial M3 Turbo S


Hi,
 I'm looking to just get started and prefer to buy used.
I listen mainly to rock and pop (Beatles, Doors, Zeppelin, Fleetwood Mac, Van Halen, The Police, Duran Duran, Nirvana, STP, just as some examples), and will have the speakers in a 16'X19' room, which has issues, I'm sure, such as an opening on one side of the shorter wall into a 5' long foyer. There's also a staircase partially in front of the back wall. I'm open to using room treatment. I can cover walls if necessary, etc..
My hunch is that I'd prefer a slightly laid back sound to aggressive and forward, which might be fatiguing for me. I'd also prefer speakers that retain a good amount of detail at lower volumes.
Have any of you heard the Meadowlark and Odyssey speakers, and can compare the two?
I'd also consider Odyssey's Kismet Reference speakers.... Thanks for any thoughts.

I remember, vaguely, the Meadowlarks from a Stereophile show about 10 years ago.  All I remember is that they looked nice and sounded good.  You might have issues if they ever need servicing, though.
I own Lorelei's withe the Kismet crossovers and I have owned Heron i's, these both are great sounding, but sound totally different. I could live with either one, but I got a great deal on my dream speakers, Verity Parsifal Encores.
figullager,
I live in Minneapolis and if you are close by, you are welcome to have a listen the the Lorelei's. 

I owned a pair of Shearwater Hot Rod's a long time ago. I liked them, but if you like to turn up your stereo they have a tendency to sound a little 'compressed' at high volumes. I own a pair of Vandersteen 3A Sig's now, so I also vote for a used pair of Vandy's. The 2Ce Sig II's would be a noticeable step up from the Shearwaters. 

I've only heard Odyssey gear at a show and then for only a track or two. It sounded quite good, so I don't think you'll be disappointed there.
