"Can You Lift Yours?"

Interesting! then there is no relation between heaviness and sound quality ?

I am not qualified to have an opinion here... I will read yours...

I gave up heavy gear for life after a 90lb two foot long foot wide amplifier monstrosity from KR Audio. I said never again nothing over 50lbs after that. And my system has never sounded better. ;)

OK, I have a story.  My MC2000 weighs 135 lb. and I had it stacked vertically above 2 monoblocks also stacked.  The MC2000 was on the top shelf sitting on a BDR Shelf for the Source (about 35 lb. I think) sitting on racing cones.

I was moving to a new house and a friend came over to spend an evening listening and to help tear down the system.  We stayed up late enjoying the music and retired.  Early the next morning, we started with the amps.  We stood on both sides of the amp and lifted it.  The plan was to lift, step sideways 2 steps and lower the amp to the floor.

We lifted, but what neither of us realized was that the shelf had adhered to the feet of the amp and lifted also.  We took the 2 sideways steps and at that point the shelf separated from the amplifier feet and fell to the floor one edge first, landing on top of the bare foot of my helper.  There was a fair amount of blood, and a quick trip to emergency was required.  Luckily no broken bones.  

The weight of the amp had disguised the fact that the shelf stuck.  

This happened 22 years ago, and my friend still reminds me that through it all, he didn't lose grip on the amplifier.  I am eternally grateful for that.

I now have the lightest amp I have owned since the late 1970’s: 100 pounds. Can I lift it? Well no. But I can move it, put it in a box, or what ever I want to do. I use my problem solving skills, sliders, levers, a hand cart and can do what ever I want with it. Same true with my heavier amps.

I believe that the HK Citation weighed in at 60 pounds, not 120.

Try lifting a BQII to a 4' shelf. 

It used to be no problem.
