We are both Lamm and Edge dealers. Our reccomendation would be to bi-amp with two pairs of Lamm M1.1 monoblocks (like that heard with the Kharma Exquisites to good effect at CES 2002) or to use Edge Signature Monoblocks. Both of these configurations will deliver a completely fantasic, out of this world performance - and coincidentally they are approximately the same price.
