I have been demonstrated P'holz Plinths up to 32mm in thickness.
I have my own one at 25mm.
P'holz excels in Transparency not Colour, every use I have now encountered it used for, it gathers the presentation enabling improved resolution and showing details, dynamics and a note/vocal envelope, that is robbed of the presence through the use of other materials.
My Case for my Pre-Amp that is being built is being produced from Permali.
The SS Phon' I am in discussion about at the present will also have a Permali case.
I have really come to like the perception of transparency that can be produced through creating mechanical interfaces with P'holz.
The use of it has superseded many of my other other set ups, and I feel confident when the system is up and running, the use of the Densified Woods will be extended further.
I can return to perceived colour at any time, as I have a selection of tricks learned over the passed years working with structures and audio devices to add a hue or dab of colour when it is desired, Blues listened to without Colour is not the Blues I learned to love.
