I started out with Maggies with one of the first Timpani 1U, later I went to the Timpani 1D and now the 3.6/R. I have used Bryston 4BST & 14BST as single amps driving the pair. But the best sound has been attained with two amplifiers with an electronic crossover. The sound really opens up with two amps. I have used Anthem MCA 2s and now have two McCormack DNA-1 Deluxe amps with the Bryston 10BLR crossover. Dynamics are "real" and the attacks are crisp/fast and there is no distortion/clipping. The cost for this setup on the AudiogoN used market is very reasonable. The single amp arrangement using the Maggie crossover was never satisfying to me, even with the Bryston 14BST. There are, of course, many other variables such as ICs, speaker cables, front end, etc. but to answer your request, I strongly recommend biamping to get the best sound from the 3.6/Rs.
