Mobile Fidelity Super HeavyWeight

Robert from Corrales, NM on 2/2/2025

Verified employee review (What's this?)

The Mobile Fidelity super heavyweight is working perfectly. I have another record weight that I've used. I thought a bit more weight couldn't hurt. And since this weight was made by the same folks that manufactured my new turntable, I knew it would work. Its much better at presenting scale on all the records I've tried so far. Glad I bought it and got it in two days...no charge for shipping.

A lump of a weight

David from Eugene, OR on 10/3/2023

Verified customer (What's this?)
Verified employee review (What's this?)

Functional yes, pretty no. It certainly works as dead weight and does seem to tighten-up the sound, but my first impression was that it looks like a large lump of coal sitting atop my turntable. For the price, a little more design effort to make it visually more attractive, would have nice.

Pros: Does seem to tighten-up overall sound.

Cons: How it looks

Adding this weight to the UltraDeck was highly recommended to improve sound quality. I haven't compared performance with and without the weight but I love how the system performs while using it.

The Mobile Fidelity Super Heavyweight Is Essential!

Donald from Bradenton, FL on 7/10/2022

Verified customer (What's this?)
Verified employee review (What's this?)

The Mobile Fidelity Super Heavyweight fits securely and easily over the center spindle of the Mobile Fidelity Studio Deck turntable. In addition to binding the record more thoroughly to the Delrin platter, the Super Heavyweight also assists in reducing resonances. I really can hear a marked improvement in the clarity and purity of my records when I use the Mobile Fidelity Super Heavyweight. This is a great accessory to the brilliant Studio Deck and Studio Tracker Cartridge package! Crutchfield, as always, excelled in Customer Service and quick, secure shipping.

Super HeavyWeight better than my dedicated Record Clamp

Jeffrey from SW Washington on 3/19/2022

Verified customer (What's this?)
Verified employee review (What's this?)

I'm really liking this record weight from MoFi a lot. I'm using the Super HeavyWeight on my modified Michell Gyro SE, instead of the Michell Record Clamp that was made for the table. The Super HeavyWeight is easier to use than the Michell Clamp, and more importantly, I prefer the sound.

Premium weight

Crutchfield customer from Hastings Hdsn, NY on 1/25/2021

Premium weight for sure. A nicely dampened rubber bottom provides vibration-free performance. I knocked one star off for the price - it's expensive for sure. But I figured I'll likely keep it forever, so it's worth it.

No regrets.

Like others, I was skeptical, but I do recognize an improvement in clarity and noise reduction. It couldn't be more simple, sturdy and understated in appearance. It's just friggin' expensive. It's a luxury, but no regrets here. It's five stars minus one for the price.

Mobile Fidelity Super HeavyWeight

Crutchfield customer from Oswego, IL on 5/24/2020

Verified customer (What's this?)
Verified employee review (What's this?)

I bought this with along with my MoFi Ultra Deck +M turntable mainly to prevent record slipping and flatten out mild warps. I figured I could something that does the job cheaper, but it matched the Ultra Deck, so spent the money. First couple albums I played were perfectly flat, no slipping (the Ultra Deck platter is slippery) so I didn't bother with the weight. Then I got to an album that was not making good contact with the platter and slipping, so employed the Super HeavyWeight. Of course it took care of the slip, but what I didn't expect was a NOTICEABLE sound improvement. Bass was clearly deeper, highs were cleaner and I felt the overall sound stage was more coherent. I'm very impressed by the performance of this little weight, and only knock off a star because (even though I love it) it's too expensive.

Pros: Stops record slip on Ultra Deck platter. Noticeably improves fidelity Looks great

Cons: Price

Nice addition to a MoFi turntable

Crutchfield customer from Hamburg, NY on 5/12/2019

Verified customer (What's this?)
Verified employee review (What's this?)

Very well made, packaged and the weight compliments my MoFi turntable. I have not had any issue with the tonearm hitting the weight at the end of a record (I read this on the internet as a possible problem). I am pleased with the weight and the only reason I didn't give 5 stars is the cost, seems a bit high for something without any moving parts.

Pros: Well made, rubber padding against the record, matches MoFi turntable

Cons: Cost

Expensive-but-essential music puck for the Mobile Fidelity TT

Crutchfield customer from Forest Hills, NY on 4/29/2019

Verified customer (What's this?)
Verified employee review (What's this?)

I recently bought the Mobile Fidelity turntable but without the center weight or "puck" that holds the records stable, and it's clear to me that this puck isn't really optional: the TT can play perfectly flat records with perfectly-punched center holes just fine, but for the other 99% of vinyl records, this puck makes the difference between playability and non-playability. Once I put the puck on top of a badly-pressed records, most of the problems go away, and images become clearer & sharper, and most of the right-pull I was experiencing pre-puck are gone. So if you've got the BF TT without the puck, buy the puck right now. Oh, I gave it 4 stars 'cause it's $200! (And I also don't know if it's any better than a 3rd-party music puck.)

Pros: sound, design

Cons: price

It does make a positive difference sonically, but on some LPs the runout grooves are too close to the weight and the headshell will bump against it when the arm is raised.

Mobile Fidelity Super HeavyWeight

Crutchfield customer from Woodbury, CT on 12/10/2018

Verified customer (What's this?)
Verified employee review (What's this?)

Looks great, and makes a noticeable difference in slight warps. May not be necessary on higher end turntables that are already well dampened or quiet, but does help a significant amount on more modest decks. If you are already happy with a preamp and stylus, this is a logical next step, but get those other things right first.

Pros: Appearance, build quality

Cons: Price

Mobile Fidelity Super HeavyWeight

craig from Richmond, VA on 7/14/2018

Verified customer (What's this?)
Verified employee review (What's this?)

My music hall 5.3 came with a screw on record weight. Although I am a skeptic with regards to such accessories, upon a friend's recommendation (insistence) , I ordered the MoFi. The difference was not the least subtle. The bass was cleaner and fuller, treble less shrill, the overall sound fuller or more complete. To draw an analogy, before the MoFi the sound was like a circle lightly and incompletely filled in; with the MoFi, the circle was completely filled in with more saturation. I am not sure why or how this works, but suspect it has to do not only with the weight per se perhaps "flattening" the record but also the "gel" contained within the weight dampening any vibrations. Just to make sure I did not experience purchase bias, I had a friend visit allegedly to listen to a new album. Unknown to him, I played the lp with the music hall and then the MoFi weight-- he didn't know what I had done -- he immediately asked me what had improve the sound, commenting that whatever it was, it certainly was not a subtle difference. He wants one now. Besides the sound, it is a true pleasure not to have to screw down the weight (as was the case with the music hall supplied weight).

Pros: truly improves the sound its "slip on" mechanism beats screw down weights

Cons: none so far (although in a way, the price is high for a low tech device).

The Mofi Super Heavy Weight not only feels well built, but fits snugly on the spindle. I previously was using a cheap weight and I was skeptical that a far more expensive weight would make a difference,but boy was I wrong! Bass is tighter and more articulate and there is more shimmer on the highs and it looks great to boot.

Pros: Definitely performs as Mofi advertised!

Cons: None
