John Darko Head Amp & DAC Weights


Recommended Posts

Hi All, for those who watch John Darko reviews on Youtube - and wondered about those cool looking weights he has on small DAC' s and Headphone Amps

They are Door stops and available at HammerBarn for less than $8 each - weight 1.1 kgs - much better than the $65 I paid for a jewellers block to do the same thing

I tried one on the front door, holding it open. Made a huge difference when I was talking to the pamphlet people who came knocking. With the door stop in place when I was talking to them it was almost

Topping A90 Darkofied - now looks like some sort of weird valve Amp....

No cables are going to pull that box around now!

Definitely not - the Jewellers block weighs 1.5 kgs - but I've now upped that to 2.2 kgs

Have also bought 3 more to place inside my new fanless PC  -may be a waste of time - but we shall see

They've got other sizes and shapes too. All about a kilo in weight. It's a shame my shelves are too close together to fit any of them.:cry:

 

Interestingly there's a guy in Europe who specialises in tweaking cases etc. that vibrate and he claims great results. Some freebie instructions on youtube.

 

As far as weight goes my new Pontus 2 DAC weighs in just a tad under 10 Kg.

Ive got a door stopper sitting on my rendu - I’m sure it does nothing for the SQ but it no longer gets dragged down the back of my rack. 6 bucks well spent. Though not as cheap as the blutak which works just as well.

Including O-rings ... or not?

From Bunnings with O-rings included?  I'm surprised.

Just ordered 2 of each of the high rise and low rider weights. 

 

I love how Bunnings home delivers now.  🙂

It’s sold as a door stop.

 

It wouldn’t be very effective if the door was hitting steel, thus the free o rings 😀

 

How about this, I’m ashamed to admit I have one. Not only does it weigh the item down, but it has anti magnetic materials inside.

 

Before anybody asks........it only come as a rat... (I know I know snake oil alert).

You guys are so extravagant - no wonder people think audiophiles spend too much money.

 

You seem to have missed this one

1 kilo weight and half the price - you can get two for less than the price of one.  Lots of weight and space-saving, too.

I don't think the flat door stop has the visual appeal of the adoored stop , and  it's not very shiny 😁

I like the idea too....these were from Aldi .

Given that the idea of these weights is to stop the lid from vibrating, would it not be a more elegant solution to apply a sheet of Dyanamat-style dampening material to the inside of the case?

Agreed....but it looks so damn cool 😉

Great idea,...until I read your post my Luxman line selector suffered the same fate .....not any longer. Cheers 👍🏻

Bunnings - an audiophiles' best friend, yet again. 

You gotta love how they undercut the audio industry's excessive profits.

Just as no-one actually tells them. If they find out I would wager that there will be a new department/aisle in every store full of shiny things that used to sell for peanuts now having their prices linked to the price of gold.

I can imagine a staff member answering my query, "Audio accessories? Just down in the snake oil section. Aisle 44.1."

If anyone wants the cachet of Swiss sourced, I've found these ones. 😉

 

Get in before Goldmund starts rebranding them 😁

 

I'm going to buy some myself, one for roaming midget hifi components and the other two to use as actual door stops.

It's only the O rings that need to settle in, so the rule of thumb is that the larger one with 3 O rings will take approx. 66 % longer than the mono ring unit

I was in the Green Big-B yesterday (for something else) and checked out the chrome+o-ring door stops.  They were nicely made and look good, the bottom was a plastic rubber, so less likely to scratch. 

 

I might go back and buy one to use as a door stop (I've already put dynamat inside some of my component boxes).

Do the o-rings come with different compliance ratings?  Would it be beneficial to do some "o-ring rolling"?

I have already changed the O rings on mine to Theraband Gold and the soundstage has tightened up considerably... 🙃

Always worth a try, report back on your findings 😂🤣

Absolutely no surprise “outsiders” think we’re nuts !

Great findings. Anyone could suggest the ones made from copper? That would be better I reckon.

A pair of them would stop the Sangean WFT-3D from sliding backwards every time I press a button.

Nice simple solution guys. Anything to help dampen the resonance.

I tried different options, ended finding a combination of methods worked best, basalt slabs, mecado stainless steel, Nordost Sort Kones, and steel weights. 

I also used two 2.5kg disc gym weights over each of the external crossovers boxes, to enhanced the effects of basalt slabs and mecados (not pictured).

The Stainless Mecados work to dissipate the micro vibrations as heat (sphere points down into elliptical cup). Nordost Sort Kones a similar idea (but double sided per device). Honeycomb lava basalt, with porous holes to sponge up the resonance.

Below, my army of resonance helpers.

I found each layer of resonance control, reduces system background noise, improves and tighten bass, enhances mid-range detail and spatial separation.

Always finding new places to improve resonance control. Home 4K Projector included! Better colours, sharper images.

Since these pictures were taken, I've squeezed more mecados between the La Scala and basalt plate (not picture below).

Shelve height limits the use of Nordort Sort Kones.

I've tried placing thin heavy gym weight discs over the top of the La Scala (with Basalt and a set of mecados underneath). The improvement were modest compared to the final configuration-

From bottom: Mecados, Basalt, mecados, Aqua La Scala DAC.

Main take home message is to never stop trying different combos.

Only problem I can see with having so many layers of resonance controlling bits and pieces is the burn-in time.

Would they be any use as a headshell weight on my Rock?

I'm still amazing at the difference small tweaks makes. Those basalt slabs (20kg each) came from my local stone and paver shop, whom kindly offered a whole pile of them for free once I explained what I wanted them for 😊

Very pleased to hear you got those slabs for nix. If you’d bought them from bocctech you’d be paying US $289 - price gouging on an eye-watering scale.
