Some might criticize my thinking, but I always plan for the long term. Maybe trading off on the intial path to ultimately get to the best destination in the cheapest, fastest way. My recommendation is to initially buy the best full range cable you can afford that mates well to your system/tastes. Use a 10 or 12 gauge silver wire(only about $10 to do both speakers) to jump to the other set of binding posts(I would probably jumper to the tweeter in this case). Then, when you have enough money for a good full range cable to the tweeter, go with a double biwire set up. I use a double biwire setup in my system to very good effect. By the way, your Bedini 25/25 is one heck of a sleeper solid state amp.
