Atzen,
I used 4 Marantz MA 500s to bi-amp my Paradigm Ref 100s, and thought it was an amazing setup, especially for how inexpensive the MA500s are (if bi-amping, I'd recommend the MA500s over the 700s, and take the money saved on buying the 500s and put it towards something like interconnects or speaker wire. The 500s will have enough juice, especially in a bi-amp config). I would recommend the Marantz route if your budget limits you from other amps. I have also used HK stuff, and found Marantz to be MUCH more musical than HK. Of course if budget allows, I'd just buy a high end amp like Bryston, Levinson, BAT, Pass, too many to mention them all...but in the $2k (used) range.
In biamping, your speakers need to have at least 2 sets of binding posts, and you will of course need the appropriate amps as well as 2 sets of speaker wire. You will also need 2 'Y' adapters, 1 male end to 2 female ends, and 2 sets of interconnects. Be sure to remove the jumpers on your speakers that would be used to connect the 2 sets of binding posts, and your off to the races. In that set up you are using the crossover in the speakers. I dont know much about external crossovers, so I'll avoid advice in that area.
Good luck.
