    I do not understand the first listing. The amp lists spec as 250-300 watt program? What 2 amps are you comparing?
    Front - RTiA5's
    Rear - RTiA3's
    Center - CSiA4
    Sub - PSW110

    Nothing really. Just marketing.

    If an amp is rated at 250 wpc into 8 ohms then that is what it is. I know Sunfire called an amp a 300~2 or something like that. It was 300 wpc into 8 ohm and it drove two channels.

    MOST PA amps used to be listed as peak and program(RMS). That's the only bell going off right now.

    Onkyo M-501-Given to my father.

    Onkyo DV-BD507 Blu Ray player

    IIRC, the "program" rating is more akin to a peak power rating, not continuous power. Today's equipment is rated using FTC specifications which means that the power ratings must state a bandwidth (such as 20Hz to 20KHz), distortion rating and continuous power within the these two parameters.

    Here is a good article from Polk that outlines what I am referring to:
