The XR45 does not output 100wpc, it's more like 70wpc. Also the amp does require about a week of running in for it's tonal balance to settle in. You need to tell us more about what kind of load the Piega's present in the bass region. Does it work best with a high current, high damping factor amp? If you're not matching SPL levels in your comparison, then your results can be very misleading. Also, party mode has no effect on sound quality.
The Panasonic XR45 is a marvelous value at a little over the $300 street price. It's a strong sonic performer in an all digital system competitive with anything I've heard for less than $1,000.
