Raquel,
You were absolutely spot on about the CAT JL2. I drove 5 hours to actually try to buy the JR 302 when I saw a used JL2. I asked the dealer to put it in his demo system (with Eidolon speakers) and know what? One minute into the demo, I decided to take the JL2 home. And the best thing is, it really brings the Extrema to a new level of performance.
