I have two Alembics, an Orion and a 1978 Series I, and they both sound amazing through any rig or combo I've tried. I know, I'm preaching to the choir...
I use an Eden WT800 and Eden 4x10 in the studio (my buddy's rig), and a Hughes-Kettner BassBase 400 and Bag End 15 for gigs. For jams, etc. I use a Gallien Krueger MB150...the smallest, cleanest, loudest little bass combo ever. 21 pounds, 12 speaker and the size of a small portable TV but it BOOMS.
The priority should be finding clean, powerful amplification that doesn't color the Alembic tone we all consider the Holy Grail. Check out Hughes & Kettner; I don't see a lot of them but they're super-clean but warm and have unbelievable headroom. I can't make the preamp distort even if I try.
