Herzan MicroDamp (MD) Series vibration isolators NEW

MicroDamp (MD) Series vibration isolators are an economical solution for applications requiring consistent vibration isolation performance over a broad frequency range. The MD Series consists of a highly compressed composite material encased in damped aluminum, offering significant vibration isolation performance at an affordable price.

MD Series isolators can be easily configured to individual instrument weights, offering a widely applicable solution for instruments between 8-3,600 Lbs. With no air or electricity required, the MD Series is an easy to install, maintenance-free solution that can be designed into a variety of instrument configurations.

Highlights

Affordable and efficient vibration isolation
Minimal amplitude within resonant frequency
Compact, modular form factor
Wide range of supported instrument weights
Easy to integrate into existing instrument setups
No air or electricity required
Cleanroom compatible
Light-weight and easy to install/use

The MD series often utilizes three to four isolators within a vibration isolation platform, depending on the supported instrument’s dimension profile and overall weight distribution. When paired with a damped top plate (i.e. granite, aluminum, breadboard, etc.), the MD Series becomes a complete solution for instruments requiring a stable and reliable vibration isolation platform.

To determine the correct isolator configuration for your instrument, review the MD Series models below and locate the model able to sufficiently support the weight of your instrument.

Please note: the values listed above are for individual isolators only. To correctly select the relevant model for your instrument, multiply the minimum/maximum load capacities by three to determine the total minimum/maximum load capacities. Your instrument must fall within this range to receive optimal vibration isolation performance. If your instrument’s weight does not fall within this range, multiply the minimum/maximum load capacities by a larger number (>3) until your instrument falls within range.

Good find, LL21.

It is so nice and refreshing to see non-audiophile pricing.

(I still shudder to think what an audiophile company would charge for my 1/2" of lead slab coated in heat-treated urethane and sandwiched and laminated between two 3/8" thick layers of steel "blanchard ground" to .005 flat per foot and .003 parallel per foot (total weight 200 pounds)!)

I can only hope ppl WILL NOT follow Hertzan advice and won't place a granite slab on top of it. Things like acrylic, thick aluminium, 'tank wood' (in Keiser speak) make much better sounding shelves.

Ron Resnick · Feb 13, 2017

I agree. My research suggests that natural granite is not a good platform. But synthetic granite, such as Caesarstone and Silestone (granite mixed with epoxy) seem to be good in theory. Slabs of steel and lead, and laminated layers of steel or of steel and lead, also seem to be good in theory.

Have you considered slate? The stand of the B&W silver signature SS25 is quite heavy and inert. It is also used for turntable plinths.

Volcanic basalt should also also be an interesting material for this purpose - its vesicular structure kills any ringing.

Agreed re slate
Considering a massively inert spiked 2-tier slate stand to support Spiers And Robertson air shelf for my slate plinth tt, and Straingauge psu

Have you seen the Wave Kinetics A10-U8s? They are about the same price.

Indeed ! I have them building my 2nd rack with the TS140 footprint but this time 3 shelves underneath the main top shelf. It will probably come in around $2k Shipped via pallet LTL freight

Yes, Jonathan, I have. I think they are a very interesting design. I would not hesitate to try them under components.

I had a 30mm thick slab of slate I rested my Kuzma TT on. After a lot of listening and experimenting I noticed it created slight motor noise break through. I got in touch with Franc Kuzma and he uses a 100mm thick block of maple. I continued the conversation and established that bonding 2 dissimilar materials
creates a much "deader" sounding surface. Hence the idea of sandwiching different materials together for TT platters.

I ended up bonding the slate slab to a 30 mm slab of polished granite with resin.

The result is a non ringing, dead support weighing a not insignificant 100Kg.

It now sits on 4 air springs, I now have a silent isolated support.

Why are there no specs for these Herzan isolation footers?

why don't you write them and find out ?

Hi XV-1:

Since the MicroDamp Series is a damped soft-mount, the performance is relative to the load placed upon the isolators, with greater performance achieved nearing the higher end of the load capacity range. The performance of these isolators will not match the TS Series, but they will be effective for a wide range of equipment not inherently sensitive to low-frequency vibration noise. We offer free demos if you would like to test the isolators with your equipment. The only information we need is the weight, weight distribution, and size of the equipment being supported.

Happy to answer any additional questions you may have.

I'm curious why granite seems to be given a bad name for use in audio platforms. From the research I've done Granite appears to have very similar properties to Steel in terms of its density and the velocity at which sound travels thru it (See chart below).

I see mention in other posts of a similar nature that talk about "Ringing" when Granite is mentioned but its density is only slightly less of Steel so why would Steel be so much better?

I have two Slabs of Surface Plate Granite in use in my DIY Audio Rack and striking it with anything else hard or even my poor knuckle results in nothing but a dead thud. Because I'm paranoid I also have the Granite sitting atop a 6" thick block of Cork just to be safe.

Granite sounded horrible under my Martin Logan Summits and when I moved those slabs under components.

cjf · Mar 20, 2017

Here is my Rack for clarity sake:

Ron Resnick · Mar 20, 2017

That is interesting. I think the dissimilar materials and laminated or bonded technique seems to work well.

Hi Reid,

Would you recommend the placement under the rack shelf, or can it be used under the equipment itself?

Thank you

Hi Reid,
They look very interesting.
I would expect that with your outfits scientific expertise you should have come up with something good and at a very competitive price. I will look forward to reading users' impressions of them.
A couple of quick points.
Is there any chance of them being at Munich this year both to hear and to buy? I could see myself being tempted to buy a set while I am there. I suspect others would be similarly inclined.
The only criticism I have of them at the moment is they don't look as attractive as the Stillpoints, at least from the photos on your site. I accept that effectiveness is more important but looks are important.

I am no techie, but i am going to guess it has something to do with the physical properties of how steel reacts to vibration vs granite. For example, if you take a hammer to steel...it dents. If you do same to granite, it cracks. That to me says something about how vibration is being received by both substances. I think the 'ringing' element probably relates to that, and intuitively, i sense a material that cracks rather than dents/deforms is going to ring more.

That said, i believe that the DENSITY of granite could be a benefit, and when combined (as with HRS) with proper polymers and other materials in a composite 'sandwich', it certainly has met with success (imho as a big fan of the HRS M3X shelves...which i believe...but could be wrong...have granite as one part of the shelf composite).
