being medically house bound since Halloween, tv overload, hopping about, I re-discovered a site with some great history:

I had a McIntosh AMP, MC2250, 250wpc, 80lbs.
I lifted it out of a low shelf in a tight space, felt a 3rd meniscus tear in my 'bad' knee while lifting.

Your Heavy Equipment Stories Please.
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. |
Interesting! then there is no relation between heaviness and sound quality ? I am not qualified to have an opinion here... I will read yours...

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. Bill |
60 lbs makes more sense than 120 lbs of course, but:, the article is my source, http://www.roger-russell.com/omni/interview.htm
60 wpc monster (dual mono) on one chassis "weighing 1 lb per watt per channel" Perhaps wording should have been "1 lb per stereo watt". Or, just give the weight!!!! |
My Quicksilver Mono Amps never failed to make my feet ache when I was forced to move them from their appointed spots. The Primaluna Integrated that replaced the Quickies isn't exactly svelte, either, but at least there's only one of them. My SOTA turntable system, meantime, weighs a ton and rocks around like a drunk in a hammock when I gotta hoist it off the rack. The tiptoes don't make the process any easier. My speaker stands are filled with lead shot, adding still more avoirdupois to the happy get-together. |
Just took possession of a Krell KSA-200. 125lbs. It’s not working, so in an effort to not have to keep lifting it up on a work bench, and taking it down, I’m going to build a table for it where it can stay until I get it working. My TT is about 90lbs including the isolation base. Not a fan of moving it as there is the issue of a rather fragile tone arm resting on top of all that mass… |
My listening room is in the second floor. My first amp was a Krell FPB 600 weighing in at 180lbs. Carried it up stairs by myself to my second floor of my home 6 yrs ago. A few months ago got my new Audio Research REF 750 mono blocks. Weighing in at 170lbs ea. carried one up stairs by myself and then had to take a break for a half hour and then carry the second on upstairs by myself. 👍👊💪 |
i will befriend you i think...😊 No armwrestle with you...

Mac 240 and 275 are deceptively heavy, and there’s no real easy way to pick them up. Bend at the knees, try and wiggle fingers under the transformer half and pray. My 240 has a nice dent in one of the transformer covers. I'm always amazed when visiting Audio Classics, beefy Mac's sitting on glass countertops. (yikes!!) They aren’t as heavy as my old threshold (100lbs or so). At least the threshold had handle bars. |
Nothing wrong with big and heavy as most audiophiles know it represents good sound. But if you considered more efficient speakers you wouldn't need big and heavy to that degree. Most folks on this website are older and there is a correct way to lift heavier objects without injuring yourself. Look into it before lifting. |
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. |
My Bottlehead DH/SET 2A3 mono blocks weigh approx. 12 pounds each. However, accessing them (bottom shelf of a rack located in a hallway linen closet) is not an easy task for me. My pilot SA-232 clocks in @ around 20 pounds as did my old Mac 30 mono blocks (per unit). My Dynaco Stereo 70's weighed about the same as a case of wine (30 pounds?). The only heavy gear I've used were Altec VOTT's in the mid 70s (after a friend built new plywood cabs for them they became unbearably heavy and I returned them to my cousin to use in his bar/restaurant). It took 5 of us to hang them from the ceiling in the bar area and the other 4 guys were as strong as Oxen (I connected the chains;-).

Placed two Mark Levinson No23's on a high shelf 25 years ago by myself...at 70 lbs each....and did not touch them until recently. My two sons-in-law got them down. In another system I have a single Bryston 4B cubed coming in at 42 pounds. At my current age, not sure I would hear meaningful difference but have never swapped them to compare.....but 42 lbs is certainly easier to handle than 70 lbs.....but I negated the advantage by using the Bryston with Egglestonworks Andra II's which come in at 215lbs each. When I move to my retirement home, definitely going with quality headphones...only. It is horrible getting old, but it beats the alternative.

Sometimes it’s not just the weight of the unit, but the shape of it, not to mention sharp heat sinks. @tattooedtrackman Colored me impressed, for sure. |
My amp weighs about 95# - I've had heavier and lighter. I can move it and feel a great sense of relief when I don't have to or the move is complete!
Honestly, I'm more sensitive to speaker weight! |
@jetter That’s Exactly right. The Krell FPB 600 was more of a bitch to carry upstairs because of those sharp heat sinks and only had handles in the back. The ARC Ref 750 have no heat sinks and have handles on the front and back. So I was able to lift them diagonally and carry them upstairs. Definitely helped. |
...and this is why ’D’ amplification, given its’ current rate of development and improvements, will prove to be a godsend to aging ’philes. Eventually, their children, grandchildren, friends, and even clueless neighbors will avoid any sentence that begins: "I hate to ask (utter BS, to begin with), but....could you lend a hand (and most other body parts) to move a couple pieces of my audio gear?" Those who hadn’t seen the parade of items that had come and gone during their time living next to said ’phile may volunteer to their later regret, although the cost of professional help to regain their previous physical state will do so. Those that have will default to the prepared ’cop-out’ that will indicate they will be as far away as possible in the next 5 minutes, lasting as long as possible. ------------------------------------------------------------------------------------------------------ My current amp weighs 48.9 lbs. Multi-channel. 6 - 2 channel amps, A & B outputs, 24 out total. Mono any or all, drive all or any one individually. Fully loaded, all 24: 30w.rms, at acceptable specs. That which I can't hear anyway, given current space occupied and equipment applied. Happy enough. At 73, I can still pick up 60 lbs. of concrete. Good to go for now. ;) Bend your knees, J |
I used to be able to. One of my Krell KRS200 monoblocks weighs 181 pounds. I could turn it on its end, pick it up by the end handles in a deadlift and stagger round the room with it. Those days are over. Like @asvjerry I am 73 and 60 pounds of concrete is no problem. |
I hope all end right for your back ? You created interesting original threads ...

@clearthinker *L* Well, since I've never weighed over 160, that's a great excuse for never owning a Krell mono...even maneuvering it onto a handtruck would have been an 'inchworm activity' (i.e., "1,2,3 *grunt*, repeated as req'd.).... @elliottbnewcombjr ....which is Precisely why I/we own a Bobcat to move this/that/the other 'round here for our biz.... A big chunk of our 'upstock' is locust logs. At 48.2 lbs.per cu.ft. @ 12% moisture....when we've logs up to 20'... Next amp for this sillie mortal: ...and Yes, there's currently a 4600 on the AG....not affordable at this time, but a 2800 would be a big step up...and I've the 'puter to push either... ...and I'm patient... ;) Heal fast, Elliott...C'ya

14.2 or 19.2 lbs.... I can cope with that....*L* Hi @mahgister.... Going totally portable doth have its' benefits... ;) |
I will not upgrade my 250 grams or less , i am not sure, dac; it will cost me at least 50 times the price to upgrade... And my back is no more a lifter...😉
