Help me shorten my list...

There is a fairly new listing here for a pair of Meadowlark Ospreys. I've owned two Medowlark models (not Ospreys) and think they are a true bargain used. BTW I'm not affiliated with the seller. Good luck.

Bombaywalla,
First, the speaker in question here is the Signature 805, although you listed the entire nautilus range, the two are not remotely similar. Second, B&W may not be your cup of tea, but the newer "S" and "D" series are not the same breed as the older nautilus line.

If you listen to rock music, I would try to stay away from speakers with metal tweeters. I have owned two pair of JM Labs (Electra 907 & 926) and think that my Soliloquy (6.2i) speakers sound better with rock. JM Labs uses metal tweeters. Soliloquy uses a soft dome tweeter as do some of the others on your list .
The inherent bad recording quality of most rock music is not too friendly to metal tweeters . This may help to shorten your list. YMMV

the Green Mountain Audio Callistos. Do some research; speak to those who own them; speak to Roy Johnson, the designer.

Totem Mani monitors at about 3000 (used) need to be considered, although they are reportedly finicky about their electronics.

Totem Tabus are GREAT, and do a lot of things very well. They've been discontinued, I think, but still can be found occasionally here on A'gon. They were around 3000 dollars new, so tend to run around 2000, sometimes less, used.

Odyssey Loreleis go deeper than you "need", but still deserve strong consideration given their price (2700 new, and basically a licensed version of a practically identical Symphonic Line speaker that sells for 7000 dollars in Germany). There's a good sixmoons review that can be linked to from the Odyssey Audio website.

If you bought the JM labs Micro Utopia Be loudspeakers, they'd have to be used to be within your budget. Priced new, at around 5000+ dollars, they then can be compared to the Intuitive Design Summits (which are about 3500 for the speakers, and 1400 or 1500 for the stands); the Summits are simply the best speaker I've personally ever heard, and I have the privelege of owning a pair. It was the audiophile purchase of my lifetime, and I have reviewed them here on A'gon.
