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 heard some Odyssey speakers at T.H.E Show last year I think it was and I just loved the sound Klaus was getting. Natural, detailed non fatiguing music and wonderful imaging. 

I have owned the Odyssey Lorelei speakers in the past, and found them to be very strong in the bass, with a very full bodied midrange. The highs, however, were quite recessed and lacking in energy....Certainly "non-fatiguing", but not balanced either. I have also heard the Spatial M3 turbo, and liked them much more. "non-fatiguing", dynamic, and not as rolled off in the highs....Quite efficient too, and not difficult to place in most rooms.
I own a pair of Odyssey Kismet Reference Floorstanding Speakers which date back to 2011.  They look like the Loreli's, but the crossover is very much different and much more expensive.  Mine came in the Santa Rosewood finish.  They are an amazing sounding pair of speakers with great bass and mids.  I find the treble to be just right.  The speakers use Scanspeak drivers and the silk dome tweeter is oh so smooth.  They can handle any amount of power you put to them and yet will sound great with lower power amps as well.  I put sharp cones on mine which I purchased from Adona.  Presently, I am not using the speakers as I have them boxed up but I can't seem to bring myself to sell them.  You should hear Pink Floyd on them, absolutely to die for.
