Magnepan, Ohm, Spatial or ??

Yes, keep the dog. *S*  They generally have better taste then their 'umans.  If they sleep through a session, that's good.
If they 'lift leg' (Sunny, our f/m, can do both...a real 'switch hitter'), then lose the speakers...*L*

Her 'aim' is remarkably accurate, BTW....;)

That's good.  I have a speaker in transit that might be your ticket.  So be patient for one week and I'll get back to you.

At the XFI Premium show in Holland last year I heard Spatial sounding good and also PAP (pureaudioproject)  I spoke to the owner/designer Ze'ev from Israel at length. He produces a 2-way open baffle design with the ability to swap the high frequency module.

I see he now builds a smaller unit compared to the D'apollito style he started with. Of course these, Spatial and PAP, were in different rooms with different electronics so I can't say which I preferred except to say both were very good. PAP will also provide drivers for the DIYers out there.

I’m ready to try/buy a pair of Vandersteen 2Ce Sig. III.
Only place I can find them is MusicDirect and the only color is mahogany. Go for it?

Or get the Signature II? Don't know anything about the upgrades to the III.

Color preference? Can't tell much from my monitor.
