The PS Audio P10 is not a standard power conditioner since it takes the A/C voltage coming in and uses DSP to generate it's own "perfect" A/C sine wave for output using a normal power amplifier. Many people have had excellent results with the PS Audio regenerators and have reported significant improvement over conventional power conditioners. Normally, I would just recommend that you go with the P10 for all source/preamp equipment and then run the amplifiers directly to the wall (since the P10 has generally made more of a difference with source/preamp pieces and less of a difference with power amplifiers). The P10 does have 1500 watts of A/C output and I would say it's good for smaller type amplifiers.
However, you have an extremely hefty integrated there (330 watts/channel and about 103 lbs). Also, your Wilson Sasha's have a demanding impedance curve and drops down to 2-3 ohms in the 70-300 hz area. This will put more demand on the amplifier and you need a lot of current on demand from both the amp and the A/C input.
I hate to say this, but I might suspect that the Transparent may do better here because it will not be as current limiting. The PS Audio P10 may have a little delay when the amp demands more current from the A/C and you may lose bass/midbass punch and body.
