DIY TT

I recently purchased a Board of Densified Wood, the Panzerholz Brand, solely to be used for TT Plinths.

A change to how I am living is creating the need for me to put the HiFi system into storage for a period of time.

With the change of plans, I have made use of the P'holz as a Sub Plinth Material with AT 616 Footers, and used it on a Valve CDP Design and a Garrard 401 TT, in two different environments.

When the devices were mounted on the footers AT 616 only at the latter part of the listening session, the benefit of the P'holz was immediately recognised for its positive influence on the SQ.

When I am up an running again, I will carry out my own further trials for this material.

There are a few companies offering P'holz Sub Plinths as their sale items, and the asking price of $1200+ can be found.

I am sure the uniqueness of the Water Stains on my boards give them a sonic superiority over the fluted designs on commercially of P'holz items😁   

Dear @vinylzone  :  " I don't need that kind of isolation.  No structure borne vibrations make it to the plinth.  The sub floor is a cement slab.  "

Vibrations or resonances at microscopic levels has a direct influence in what the cartridge stylus can pick up due theat the cartridges are en extreme sensitive to any kind of " movement ".

Seems that your statement is mainly subjective and I think that you need to measure as @mijostyn posted, I' agree with him .

Several times with original stock TT/onearm designs we just can't be aware of those microscopic " distortions " because due to the resolution levels of the room/system we can't be aware of that or maybe because we don't yet know what to looking for but what you can be sure is that those " distortions " exist and modulates the kind of colorations you are listening in your system.

Of course you are satisfied with what you have and looking that you like the DYS kind of work making measurements of what you did could be interesting for you or maybe you just don't care about.

What Raul says is undeniably correct, but I don't think a spring suspension is a panacea that puts an absolute end to "vibrations and resonances at microscopic levels".  In fact, in some cases, or if badly implemented, such a suspension can make matters worse.

@lewm  , you always has a " but " and it's ok with me but then please your perfect solution about, we need your contribution for all we can learn.

A recent new Member to my local HiFi group, has been quite impressed with the Isoacoustics Oria Footers that they have been loaned to try out in their system.

Following the experience with the Panzerholz and the AT 616 Footers the same person has sent out a link to the HiFi Group of a device they are considering buying for there TT.

It looks like it is a substantial piece of kit and hopefully if acquired it will prove quite valuable to their set up, it can be seen in the attached link.

I have set speakers up in the past on Heavy Plinths with AT 616 feet under the speakers and got very pleasant results.

I have set up similar methods for others, using their speakers and the result has been either Isoacoustic Gaia Footers are now in use or a Townsend Sub Base.

The Footer I use directly in contact with my TT Plinth is the Solid Tech 'Feet of Silence'. I have yet to have this footer improved on.

My assessments are subjective like 1000's of assessments, I don't measure such things, as I don't know how to do so accurately.

The most commonly used vibration measurement methods, which are using  accelerometers and laser devices as the methods to measure are not suitable for vibration measurement of micro vibrations. The methods referred to as Optical interferometry has the advantages of being a non-contact system and measures to a very high accuracy.

Devices to measure ambient vibration accurately and that can supply a trusted reading of a condition that can have a detrimental impact on a stylus when positioned in the LP groove are not very affordable, and are certainly not on any HiFi enthusiasts that I know equipment list.

I do believe there is a lot more available to impact on a stylus in a detrimental manner manifesting from within a Bearing Assembly, Bearing Housing Mounting Method or from the Tonearm having design flaws where bearings are as friction free as can be or internal wiring is restrictive to free wand movement. 

If the TT and Tonearm have both cncerning conditions in conjunction I don't think knowing about ambient micro vibrations and putting in control measures is going to have too much a impact on the overall situation.
