How do you know if your amp is putting out @ Rated Wattage ?

I just bought a Rotel 1095 (200W X 5) through ebay to replace my Rotel RSX 1065 (100W X 5 Receiver that I was using as an amp through Pre-Out In).

Upon playing the new amp I can feel the 1095 to have slightly higher volume levels than the 1065 but dont feel it is putting out DOUBLE the power of the 1065. (I am able to increase the volume to level 80 / 100 and dont feel it is to be super loud..) 

What would be the best way to ensure the new amplifier that it is working properly and putting out the rated 200W ?

Thanks in advance for the guidance

PS - All channels are working and amp is running cool.

To get 2x the perceived volume you need 10x the power. :) 2x the power is only 3 dB louder.

Best,

Actually is is 6.8x power increase, for perceived volume doubling, from research studies on listening.

According to my calculations it is about 11x

Perceived loudness increase = k^(1/3.5)  , where is ratio of power.

11^(1/3.5) = 1.984

Some studies mention k^0.3     (10^0.3=1.995)

Thanks everyone for your perspectives. Really appreciate the insights. 
Everything seems to be working just fine. I was doubtful if the amp is operating at specs.

I definitely can hear better sound and improved base response than my earlier amp.
