PS Audio used with BAT VK-60 monoblocks

I have a PS-AUDIO 300 (used with BAT VKD5SE CD player) and a PS-AUDIO 600 (used with BAT VK50SE Preamp). I like the results of the PS AUDIO gear, but, the problem is that the units do not allow for enough power to be drawn to service the compoenents. Thus, I purchased a PS-600 just for use with the BAT VK50SE Preamp. I also have BAT VK-60 Monoblocks (awaiting return from a BAT "SE" manufacturer's upgrade. Currently, I use BYBEE QUANTUM FORCE CHARGERS on the Amps. I am particularly intersted in purchasing a PS-AUDIO 1200 (new product) for the Monoblocks. Will this offer enough juice for the Amps without "choking" the sound? Also, any recommendations for Interconnects and Cables. I have Reference 3a Royal Master Supremas as speakers.
