Densified Wood has a very different measurement to nearly all materials typically used as a Plinth.
From knowledge gathered there are only a few substances that are close in measurement to damping factor measured in a Densified Wood and none of these will be referred to as Typical Material seen in use.
Densified Wood also has a quite different frequency to other materials and it is this combined with the Damping Factor that places it where it is with desirable measurements, and seen ideal to adopt the role of a Plinth, and is becoming used for other roles as well.
Panzerholz, was one of the materials promoted in the earliest days by those who were using science to prove the value of moving away from a Mass Plinth.
Possibly due to the Brand being readily available in Mainland Europe and for quite a period of time in the UK, it is a Densified Wood that has gathered a popular use with those expressing an interest in this side of the Science and available Technology to support it.
It has to be experienced in use, there is not easy ways to describe how it use, a whole new insight into how a recording can sound will manifest.
Combine this with PC Tripe C Wire as Upstream Signal Wire in a Analogue Chain and there is a tremendous amount of betterment on offer.
I really do hope a Cart' is produced with this wire as a Coil Wire in the not too distant, that would make not just one person happy.
