"It is learned that vibration is archenemy affecting acoustic quality. Usually there are two resolutions. One is absorption; the other is isolation. But the XINDAK engineers have developed a new device, named as Spherical Cone Baseplate For Vibration Tuning (SCBVT), to solve damage to acoustic quality because of vibration. Its principle is to convert vertical vibration into horizontal displacement. The structure of SCBVT is: putting a ball in a pit of compact inert material, the base of acoustics put on the ball in a form of point contact. The result is: first, it makes play of isolating vibration; secondly, hazardous vibration of acoustics equably spreads inside the whole inert base through the ball and is absorbed. Meanwhile assortment of the base and the ball material is able to tune hazardous vibration of the former system in frequency point hurtless to acoustic quality. It will greatly reduce adverse affection from vibration and improve acoustic quality. It is enough just to put three blocks with balls like a triangle under acoustics such as CD for use.
My Experience:
Material: Base made of graphite of high purity (99.99%) + Ball made of Hard steel
Upon installation (3 pcs) obviously there is an improvement on details, Instruments like Piano, Violins becomes real. I also notice huge improvement on Bass, not more punch but more depth & low frequency extension.
Soundstage becomes more wider. Mids (Voice) more fruity & airy. Overall it's just like I'm using new high-end CD player. But for the price of no more than my sigle Date with my EX-Girlfriend (My wife).
For Tweakers focusing on Cables & IC, you must try this instant tweak. (IMO)
