Newby question on watts...

I have aquired an older amp, Audio Research D-100 rated at 100 watts. Weighs 48 lbs. Sold my 1st amp, a Hafler 220DH rated at 115 watts, but only weighed 24lbs. What am I getting for the extra 24lbs? Nothing/something? If both have the same output, what is the gain for all that extra weight.

Thanks for responses. The Hafler went to 170 watts @ 4 ohms. I am using 4 ohm speakers. The Audio Research has never listed their power into 4 ohms? I assume from the beef of the unit that it can easily handle these 4 ohm speakers?

Stanwal....
I was actually more curious in what I was getting out of my 48 lb amp over the 24lb Hafler receiver, because they both put out 100 watts@8 ohms(both of the same vintage). I was just wondering why a unit needed an extra 24 lbs. to put out the same wattage? Speakers are an old pair of ADS L710's I had rebuilt. Tubes don't really enter into equation. Thanks, Gary.
