If your short list is still open give theFoundation Research LC1 some consideration.
While not the most Esoteric of power cords, I think the real advantage of the Foundation Research LC1 is that it's a Bi-Directional filter, and filters the current in both direction.
The importance here is it back filters the noise that is being generated by the normal digital operation, and sent back out, down the power cord, and back into your power conditioner, where it can pollute your other components.
Because the F/R LC1 has it's own filter built into the cord, you can plug it directly into wall. This would eliminate any signature that may be imposed by your power conditioner, and if it's plugged into the wall there is less chance of your 3910's power supply being modulated by your amps larger power supply ... if they are both plugged into the same power conditioner.

Rationale: The ac power line injects noise into audio equipment. A filter removes noise from the ac power line by presenting an impedance mismatch to the undesirable noise signal. An impedance mismatch reflects noise back into the power line. This fundamental behavior is that of a band reject filter.
Another source of noise is the audio equipment itself. The power supplies in audio equipment inject noise back into the power line. Large power supplies like those in power amplifiers tend to create more noise. A power amplifier delivers noise to a preamplifier plugged into the same power source. Digital components can also be significant generators of power line noise.
