Thread: Active Anti-vibration Platforms : Accurion i4 and Herzan TS150

    Talking Active Anti-vibration Platforms : Accurion i4 and Herzan TS150

    A number of WBF members are active anti-vibration platforms users. There is a long discussion thread : http://www.whatsbestforum.com/showth...solation-table

    However, this is a new tweak for audiophiles in Hong Kong. One of the reasons is the high price. Luckily, the Euro is low recently, making prices of these European products a bit more accessible.

    Two brands are available in Hong Kong : Accurion and Herzan (Table Stable).
    A gathering was held last weekend by my friends and I to home-test both and to select the suitable model for group-purchase.
    They were tested in 4 home audio systems, all are pretty highend (Alexia; Q7; Mini2; Goldmund). Some have LP system and some have digital frontends.
    All the 4 systems were in concrete apartment buildings.

    The Herzan HK dealer sent a manager/science officer to accompany us, doing measurement on the floors, racks and gears with his lab-grade equipment.
    Herzan's main customers in HK are labs of universities & hospitals and he does such field measurement & installation there quite often.

    Below is a photo showing the two platforms tested (Accurion i4 and Herzan TS150). That mediocre all-wood table is for photo-taking only. The two platforms were tested on much better hifi racks.

    Are you running a group buy ? Would it be possible to take part in such a group buy, even if I'm not HK based ?

    There are many photos. Here are just a few on different frontends.

    We tested the platforms on preamps too.
    Poweramps were not tested. They were heavy and we didn't have enough time.

    Hi Adam,

    I will send the contacts and the prices to your mailbox later.
    However, I am not sure if the HK dealers are willing to sell cross-regions.
    Also, the prices in HK may not be the lowest, due to shipping costs from Europe.

    Have you noticed any performance advantage with one unit over the other ? The both isolate well below 1Hz so I suspect any advantage would be negligible at best.

    Christian, good isolation previously was anything around 3-4Hz. I think a Vibraplane and Minus K are around 2.5-3 Hz. Then came along these active units which go even lower than that. But what exactly does "isolate well below 1 Hz" actually mean in the real world? What kind of resonances are there at that level, though I don't even know what level we are talking about.

    I'm also curious if the group heard any differences between the two units.

    I am currently in the process of buying a UK-made Spiers And Robertson air rolling diaphragm shelf, 24" x 24", for my tt that will sit on an inert spiked slate table. This is in effect an up to date iteration of the Vibraplane concept, and is good for isolation similarly down to 2.5Hz. The discussion on active isolation going down to 1Hz came up, and the conclusion from the Spiers people was that 1Hz frequencies are generated by sub sub sub bass phenomena maybe many blocks/miles away like wind turbulence, roads and bridges flexing, underground structures resonating, earth movements etc. Now if you really believe these phenomena will be massively significant re tt performance, than by all means go ahead and buy the pricey $15k/10k Accurion/Herzan shelves. Our conclusion was that for real world applications, the Spiers air shelf at 2.5k/$4k is just as practical for all intents and purposes, and a damn sight more affordable.
    The other advantages the Spiers shelf has is: larger footprint than active/Minus K (even bigger available too); more reliable air bladders than Vibraplane; and less fussiness w/need for optimal loading like the Minus K. My idea is to use the spiked slate table as in effect single tier stand, the Spiers shelf on this, and to load a Symposium Acoustics Ultra shelf on top in addition, to deal w/vibrations in the 5Hz regions.
    Interestingly, the Spiers people are adamant that active isolation is optimised for static non moving devices like electron microscopes, whereas their air isolating shelves are used on measuring equipment w/moving components analogous v.much to a tt/tonearm arrangement, making it a more appropriate choice mechanically.
    I know that Keith of Purite Audio has demoed/measured both the active Accurion and air Spiers, and in quite a few ways the measurements on the Spiers was superior in pure isolation terms than the Accurion, and had the edge in SQ too - good enough for me.
    This venture will end my OTT/OCD attempt at SOTA tt isolation.

    Hi spiritofmusic,

    Thanks for the info.
    But to be frank, we did experience devices using air-bladder mechanism before and we want something better and diff.
    I have not posted all our findings yet. There is a tweak that has elevated the performance of Accurion to another level ...
    I will post our findings today.

    Discovery 1 :

    The Herzan scientific officer told us how to select sites for installing the active platforms. Essentially similar to what Mike Lavigne said in another WBF thread : concrete floor, not tall rack/table, rigid rack/table ... etc.

    When he measured the baseline vibration before applying the Herzan, he found:
    - Apartments located on lower floors have less vibration, although all are concrete buildings.
    - Apartments located in an island (Hong Kong Island) have more vibration than those located in a peninsula (Kowloon).
    - The location of the component relative to the loudspeakers is important because the sound wave makes direct impact. In fact, when one of the people in the room shout, increased vibration can be detected on the rack & component.
