SF Power 1 Integration

I'm starting a process of upgrades for my current system. I'm currently running an NAD 712 receiver with an NAD 513 CD player, MIT Terminator 5 Speaker Cables, Cardas Interconnects (can't remember which ones), and Paradigm Monitor 7 speakers. I am wanting to purchase a Sonic Frontiers Power 1 amplifier, and I'm wondering if I can integrate it now with what I have, or will have have to buy a new pre-amp before using it? It will be a slow upgrade process, but I plan to replace everything in my system at some point as the money becomes availble. Any suggestions or recommendations? Am I wasting my money buying this unit first?

Thanks.
