 Reviews of AVM
Show covers/Industry News from the Montreal audiophile show April, 2005
From Enjoy The Music
I have tried the AVM* in many occasions on various high end audio components, such as equipment fuses, transformers, vacuum tubes, cables, circuit boards, etc. The sonic improvement in each case is immediate and positive, and the amount of improvement is very large. In my over thirty years of experience as an audiophile, other vibration damping materials were used, but the end result was mostly mixed, with some negative effects and some positive. None has been proven to yield the following: 1.
Quality Of Sonic Improvements: 2.

A Review from Marlen Mogilever,

Dear Ban, A review from Mr. Rick Schultz, president of Virtual Dynamics cables and President and Co-designer of Luminance Audio Anti Vibration Magic I am Rick Schultz, designer and president of Virtual Dynamics cables and President and Co-designer of Luminance Audio. I was introduced to AVM as one of the first people fortunate enough to try this product. I specialize in vibration control for audio products and had a keen interest in Anti Vibration Magic. When I was first told about the product nothing could have prepared me for the result of my applications. I have used AVM in nearly every practical application including transformers, circuit boards, tubes, transistors, chassis, capacitors, cartridges, tone arms, motor drives, speaker chassis, drivers, crossovers and more. The result is a lowering of the distortion noise and increase of sonic performance that has been unequaled by any other single product I have encountered. I have found blacker backgrounds with better energy while maintaining better control in virtually every application. “AVM is likely the most versatile and effective product I have yet seen for consistent sonic improvements. The amplifier transformers on my tube amps resonated so loud I could hear them from my listening position. After a single application of AVM on one side of the housing the volume of this vibration dropped so low I had to put my ear directly up to the transformer to hear it! After treating the exposed outside wire and several other areas of the same transformer I could hear vibration only with the use of a stethoscope. In my experience transformers, circuit boards, and tubes are most greatly impacted by this product. Speaker drivers also are incredibly impacted by AVM and offer the biggest area of audible improvement overall. Simply, AVM works anywhere you put it, enough said! Prepared by Rick

end揚聲器製造商之一，我們很榮幸測試AVM，現將整個測試過程和我們對AVM的評價公佈如下：
我們首先生產了兩對我們當前最頂級的書架式揚聲器
(型號為VOLLA)，這兩對揚聲器的所有部件都經過嚴格的測試和配對處理，也就是說兩對揚聲器上使用的高音單元，中低音單元和分頻器元件的技術數據幾乎是完全相同的。揚聲器裝配好以後，我們又使用了LMS進行了測試，在確信兩對揚聲器的靈敏度、頻響範圍、阻抗和SPL完全相同的前題下，我們將其中一對VOLLA揚聲器的分頻器、內部連接線和中低音單元的框架均勻的塗上了兩遍AVM
NO.2 (總的用量大概為60mL)。待AVM充分幹燥後，將揚聲器裝配起來，然後和那對沒有使用AVM的揚聲器進行聲音對比測試
(主觀評價)。
參加聲音對比測試的人員為兩名，花費時間為4小時。在聆聽過不同類型的測試曲目後，我們認為，使用了AVM揚聲器的音質表現有了非常明顯的提高，具體為音樂的背景變得很乾淨，3D效果更加明顯，高音細節豐富，中音透明圓潤，低音乾淨俐落，深沉有力，揚聲器的瞬態特性也得到了很好的改善。總之，使用了AVM的VOLLA揚聲器對比那對沒有使用AVM的VOLLA揚聲器，在音質方面有了大幅度的提高。
另外，我們還將AVM塗在我們的型號為AC165/50C2C
6.5"中低音單元的音圈上進行對比測試，結果是SPL變得非常平滑，我們認為在音圈上使用AVM可以吸收部份中低音單元的有害振動，從而達到降低單元失真的目的。
結論，從我們對AVM主現測試的結果來看，該產品能有效的全面的改善揚聲器的音質，並且效果是顯著的。 李曉琳 此信息由Aurum
