It would all depend on the efficiency of the JM Labs.
You've got a great pair of speakers, I've owned them. As you improve your system, they will sound better and better. I'd take the money the dealer wants you to spend on JM Labs and buy some electronics. Going to a system high power amp like an Adcom and Adcom preamp would probably sound much better.
