I think the meanings are lost in translation because the explanation is fragmented such that it reads like the musings of a scientist losing his grip on reality. The theme music from the old TV series "The Twilight Zone" comes to my mind after reading.
In recent posts I have referred to KSA3503 and KSC3503 - of course the latter is correct.
Re isolating the transformer from vibration that in the photo looks to be quite heavy so if the plate is aluminium it would need to be a reasonable gauge to prevent this plate from flexing. The transformer is in intimate contact with the plate which would be in contact with the safety earth. One would not isolate this electrically through some mechanical means. Aluminium is a good conductor of electricity. It is unclear what internal fuse protection there is place for the mains supply - apparently protection relies on the multi outlet box tripping out after major damage could have occured within the amplifier - and in the low tension side of the amplifier.

Er, which photo do you refer to in the above post? Is it the Statement transformer mounting assembly?
On the general issue of spikes for eliminating vibration; consider that they may reduce the transfer of some vibrational modes to the supporting framework but at the cost of focusing the transfer of energy at wavelengths related to their spacings. The design of a 3-point mounting for example, may actually be rather complex and could also result instead, with the increased transfer of some unwanted harmonics, peaks and intermodulation products to the mounting frame and casing, as it happens to be. A trap for the unwary.
As DIYer, I think I would use the broad-brush approach and rely on damping materials instead.

caglarm post 8563. Not the Statement shot in post 8581 for transformer mounting assembly. I have a Naim Nait amplifier although inaudible at a normal listening distance the distictive throbing sound of the transformer can be heard if one is close enough to the equipment. In the statement this could be as much about micro vibration and partial shielding of the transformer electric field. It has been claimed that toroidal transformers have optimum orientation in the last regard. If I remember is not the Statement a tower-like edifice - one that might not get much wife approval rating - as in you can take that to the art museum you are not bringing that thing in here!

On huge rooms Statement may look ok and the target buyers probably have them. I was wandering how you move the boxes around but the underplate is part of the chasis and the transformer is bolted on (big transformer). Decoupling by minimal contact points and small surface may work better though, damping materials will probably transfer energy as well. Maybe a combination of both.

I would orient transformers so that their EMF is lowest at the listening position. Because their EMF are enormously harmful to health, up to heart attack, stroke, cerebral apoplexy. A toroidal transformer arranges standing, so that you could look through its "hole";-)
I would do a mechanical decoupling by ear: tonal tuning. Different materials sound different, whether rubber, metal, stone, wood...

All credit to them for the effort they put into decoupling and tuning: Naim-circuits are too complex to get a clean sound: "high end". No way;-)-;
I have a Naim amplifier - it doesn't come with a Government Health warning label. These days commercial electrical products follow established international standards for safety in order to be brought into the market. Most warning labels are to the effect no user serviceable parts inside. Opening the case for a look inside could result in breach of warranty conditions. If one was to do this the risk the mains feed including inline fuses would be insulated as per the international standards. That was not always the case - I have a Sansui AU417 that was gifted to my brother that has a failed channel that I am looking to repair. There are signs that there have been repairs some time in the past. The mains fuse in this is not accessible from the back panel and it is on an internal board nude in a standard clip fitting.
I suggest you think more before you go into print. What you have written by way of health impacts has no credibility.

Not credible for a commonly trained electrical engineer. But for physicians trained in this field or scientists in the field of mobile radio, military, secret service...).
Mobile radio is THE key technology of the New World Order. The electromagnetic fields serve not only the transmission of porn and cat pictures, but the control, monitoring, control and also sanctioning, up to killing. And low frequency emf are really easy to apply for mentioned "incidents"-)-;
yes, it provides vibration, thermal and electrical isolation
I use felt for this. (attached to the legs of chairs)
The plate under the transformer is 1 cm thick. It is not possible to stretch. The transformer is connected to the plate at 2 points. The bottoms of the other legs are filled with felt. Air flow is provided from under the transformer. The temperature of the plate is not transmitted to the transformer either. The transformer is electrically isolated from the plate. The transformer is also connected to the main earth. Connection screws is also isolated
I'm sure that all the transistors I have are original. Most of them were bought 30 years ago. At that time, my country was not made in China 🙂
But still the ksc 3503 sound more musical, closer to the tube amp
emf stands for electromotive force which is what drives your washing machine motor, your vacuum cleaner, your electric drill etc. you are not in any danger when you use these appliances and tools unless you injure yourself on such as a power saw blade or tripping over a vacuum cleaner power cord.
2N1711 is still currently available - I mentioned this in post 8561 with brand names and reliable warehouse sources.
Electro Magnetic Fields I mean.
All biology is electrophysics only. We measure the "loudest" signals by ECG, EEG...
We could expose a human being to a phase inverted ECG signal of his heart.
Or we modulate it with other frequencies. Or "pull" it into another frequency range. Or "drown" it out.
Or we make blood vessels spasm. Or or or;-)
Hundreds sorts to kill;-) Tens of thousands of ways to make sick;-))

Leave the "we" out of your comment about exposing a human being to a phase inverted ECG signal to his or her heart or any of the other means of torture in this rant.
