"Can You Lift Yours?"

The Citation II doesn’t look like it weights nearly 120 lbs. Where’d you get that number? I would have guessed 80 max. My VAC Master 300 monos are ~ 135 lbs each. I had them moved here by the dealer. Not worth the risk. I’ve got 2 other tube mono amps each 100 bs per side, and the Masters sound so much better they could be 1,000 lbs and I’d still try to make it work. I’ve moved those other monos myself a hundred times trying to figure out which I liked better, ugh. The arrival of the Master 300's put a STOP to that nonsense. 

Any correlation of sound quality to weight has to be predicated by amplifier topology. Traditional tube amplifiers probably have the strongest correlation here, because the size of its transformers (power plus 2 outputs) generally dictates how much power can be provided at reasonable distortion levels. ~ 1 pound per stereo watt is not uncommon. Of course the raw power itself isn't a perfect correlation to sound quality, but the weight (transformers) is definitely a big factor in distortion and bandwidth. This is how people got an inking the Carver amps weren't on the up-and-up about their power ratings (only 19 lbs for 75 stereo Watts is a red flag).

Next is high-bias class AB and class A solid state amplifiers, which require large amounts of heat sinking and still a very large PSU (power transformer). I'm a tube guy but I'm still quite fond of some of these. 

Then you have class D which can be made extremely light relative to their power output, and the correlation becomes very weak. They can sound good! I don't hate them; they're just not my thing.

The amp's form factor is absolutely a big deal. My VAC 200iQs weigh 100 lbs each and it's just a box with absolutely no handles or grips. The distribution is very front loaded, where the transformers are. For proper front-to-back balance you have to slide your hands under just the RIGHT location a few inches back from the faceplate, or it will try to tip out of your hands and you're about to have a real bad time.

By comparison the Rogue Apollo is the exact same 100 lbs per side, but its chassis has built-in handles, and it's a more balanced distribution, and this effectively makes it "seem" around 30% lighter (or so). Fortunately tube amps don't have sharp heatsinks, but that could be a nightmare on some amps. My Phison A2.120 has very sharp edges but it's only ~ 50 lbs so not an issue. 

My VAC 300iQ monos at least have some chassis structure (rails) that can be used as handles but I haven't tried to move them myself. 100lbs is my "safe limit" for just myself.

I highly recommend IronClad's Command Grip  work gloves for moving heavy audio components.

Well, yuh....but ones' personal form factor remains the bottom line, esp. when the hands hit the chassis...  Unless your posted pic is a file photo from youth gone by, you've got a built-in 'cheat'. *mock grumble*  And it's vaguely reassuring that the 300s' pose a challenge to you, Commanding Grips notwithstanding.... ;)

@asvjerry I look like I can lift more but lower back has increasingly become a weak point. I know lift with the legs, keep back straight etc, but all it takes is one absent minded moment and I get a week of back pain & hobbling :(

Also my grip is a relative weakness (hence the gloves). Alas, the "gym bro" thing was fun for a while but I was not made to lift big #s. In my 40s now I've decided to give up the gym for swimming laps. 

Take care of your backs, guys!
