JMLabs Alto BE / Verity Parsifal Encore / WP7?

What type of sound are you looking for and what type of music do you prefer?

Music taste and room size/placement options would be helpful too. All three speakers you mentioned are excellent, but they all seem to excell in different areas.

I listen mostly to jazz, classical and light pop. My room is 11'x18'x9'. I like a clean transparent sound. Thank you for your response, any suggestios would be greatly appreciated

In my opinion the Parsifals are perfect for your room. They work well relatively close to side walls (imprortant as your room is only 11' wide, unless you want to place them on the wide wall), and they don't need a lot of space behind them (especially if you set them up with the woofers firing forward). With the Wilsons and JM Labs, you might find the midbass overwhelming in your room. The Parsifals are wonderfully transparent (the mids have the "see through" quality reminding me of Quads), clean, dynamic and at the same time smooth and musical.
All of the speakers you mentioned are great designs. In a bigger space it would be a tough choice, for your room, I'd say go with the Parsifals.

The new Acoustic Energy AE3MkII kills the Verity's in transparency and dynamics and works extremely well in a small room. I would urge you to seek these out for an audition- check out the review in HiFi Choice.
