Equitech Son of Q vs. Son of Q Jr.

The only thing I want to plug into a power conditioner is a 30 wpc integrated amplifier: an ARS-Sonum Filarmonia. I have a dedicated 20A circuit. Does anyone have any experience comparing these? I'm assuming that the neither will have a problem handling a relatively small amplifier, but I'm wondering if there would be an appreciable audible difference between the two.
