Just moved and have a smaller audio room 10.5 x 15

Should be a no brainer. Go with the Quads. You can always sell them for what you paid for them if you don't like them. Of course with the Quads you will probably end up looking at nice tube amplifiers to drive them. You know one thing leads to another...

the VR-4s are too big for your room. If you were happy with your SP1/2s might you consider a different Spendor like the S8e? Darned good speaker.

I would just add some info about your room. One listener above suggested the long wall should be behind your speakers. Try it, but also try pulling your speaks out three or four times there depth from the short wall behind your speaks and two to three times times their width from the side walls. You will have the opening of your room behind your seated position in that case which is a good thing, IMO. Where to put your seat? If you are thinking that your speakers wouldn't be spread apart far enough in that case, remember that's its all relative. Try sitting at the apex of an EQUIDISTANT triangle first with some toe-in. Move your seat back, or not, season to taste.

If you wind up with some planar speakers, the suggestion about the long wall is particularly worth trying at 24 to 28" out. If you wind up with some dynamic speaks with a tight grouping of the drivers like the Usher Tiny Dancers, they will disappear with an equidistant triangle, no worries. And your stage will open up in ways you may not have experienced. Happy trails.
