Comparative help...

Hello all.
Has anyone had the opportunity to compare the 'Joseph Audio Perspectives' with the following speakers.

Revel Ultima Studio 2
Canton Reference 3.2 DC
Thiel CS 3.7
Marten Django XL

They all fall into the same price range and I am looking for some 'perspective'...if you will.

Any reply's would be most appreciated.

Thank-you...

Mark
