I went from Paradigm 100.2s to JM Lab Electra 926s in my system. The difference is unbelieveable. The JM Labs have a soundstage precision and timbral finesse that the Paradigms never could muster. The other big improvement is in resolution where the JM Labs are simply in another league.
On paper they have a teeny bit less bass but its quality and integration is so good that you don't even notice. I highly recommend them; especially now that they go for $1900 or so a pair. I got 100.2s becuase they came from a vertically-integrated company and so I wanted to continue the theme - it was an excellent idea. Good luck! Arthur
