One turntable with two arms, or two turntables with one each - which would you prefer?

It has been difficult to suggest a Densified Wood to be considered for use in the USA as there are not too many Brands able to be found.

Thanks to the TV Series 'Forged in Fire', I have seen a material used that captured my curiosity and have now discovered the correct name for the material that somebody who is developing a curiosity for a Densified Wood might like to look at.

My searching for Diamond Wood, has commonly not found the wood type I was looking for.

A different approach has found Dymond Wood.

This is more like it, a Birch Wood Veneer Board, that begins as a 2 Inch assembly of Layer and is compressed to a 1 Inch finished product with a plastic resin type of adhesive.

The description is very in keeping with the Wood Type I am an advocate of. 

The properties that make it more akin is the Weight I have a Dymond Wood at approx' 1300Kg per Cubic Metre, which is undoubtedly a Densified Wood.

The Compressive Strength and stability when submerged in water is very attractive, this material is extremely stable and will not expand or yield in any usage for HiFi.

You could make a plinth large enough to use a M4 Sherman as a Tonearm and it will be the ideal Plinth Material.

Hopefully the info' will be of use to a forum member for their own trials to commence.     

@pindac Try Panzerholz. You can order from their Canadian distributor BK Industrial. About $1000 for enough to build a plinth. Very difficult to work with, but I managed to complete a 2-arm plinth for my Technics SP-10 MK3.

@au_lait I am quite familiar with Panzerholz and Permali, I have some very nice P'mali Boards and am fortunate to have purchased a supply oof P'holz with a friend who has CNC Produced a P'holz Plinth for both of our SP10 Mk II's.

I have listened to the SP10 Mk II in a P'holz Plinth for a few years now, at another friends, and this past weekend on Saturday, was demonstrated one of the CNC Cut Plinths produced for the SP10 MK II, for the first time in my friend's system since it was exchanged from a Marine Plywood Plinth. 

The P'holz Plinth has been mounted on to a P'holz Sub Plinth to create a Two Teir Support Structure.

My comments on the last occasion I visited, when a Marine Plywood Plinth was in use; was based around detecting a detractor, of which the fundamental cause was suggested to be from the Cabinet Speakers. I was awarding the Speakers Cabinet as causing coloration.

This Time around, I was very quick to make it known the same Speakers were quite transparent and getting a fix on their placement was now much more difficult, the coloration that was suggested as being present in the speaker's had seemingly disappeared.

A set of Electrostatics were also put to use, and the Cabinets and ESL's were seemingly with parity when it came down to Transparency.

One other point of interest is that on a very well-known Album, I was confident that the replay on this occasion, was delivering information, I had not detected before when replayed on a selection of systems. 

The change of Plinth Material in this case has had a notable effect at managing a distortion that can be passed through a Styli, and manifest downstream at the Speaker. 

I can't help but think the Sub Plinth has been instrumental in assisting with the additional detail being detected in a replay. As a P'holz Sub Plinth has proved quite a valuable addition to other equipment used at demonstrations prior to Saturday's Visit.  

I know the cost of receiving Panzerholz outside of Continental Europe can be quite prohibitive.

Permali is a Densified Wood that is a little easier to find, maybe the licensing for the product is eased.

In general, I encourage a search for Densified Wood as most Countries produce their own Brands, that all share very similar properties, it seems the weight for Overseas Shipping seems to be restrictive, hence the home-produced material. 

The Dymond Wood is found in a Board and is found in many colours, this might appeal to a would-be Plinth Builder.  

@pindac Very nice. Is the sub-plinth beneath the main plinth, or is it a plinth within a plinth? Mine is 6 layers and sits on Townshend pods, but I might build a sub-plinth if I go for a second round. 

One thing that decreased my cost importing the Panzerholz was having panels pre-cut and shipped in boxes as opposed to whole sheets that would have required a pallet. I will look into the others you mentioned as well.

The Link will help with introducing information, that will supply a broader knowledge of D’fied Woods and show that densifying wood has been an evolving practice for nearly 100 years.

Page 37, shows the Brands that are produced across the Glode, in my humble view, it is these Types of production, when produced to this standard and using the Adhesive Selected, that are the most beneficial to be used for a HiFi Set Up.

Kaiser Speakers use P’holz for their Cabinets and refer to it as Tank Wood, there is a Article on this Company, that has a very good description of the valued properties available from P'holz.

Other Speaker Brands and Kits are also utilising P'holz and Permali as well.
