my wife has a gold chain she never uses, maybe. . . :i
what i mean why wood resonances influences component, at least as i understand it.
Thru the components is a complex signal build up "contaminated" by eddy currents. These eddy currents are 100% consistent with the "movements" of everything conducting electrons in a magnetic field be it static or dynamic and or moving metal in an electric field creating on its turn a dynamic magnetic field and or moving electrical fields creating in static metals a dynamic magnetic field.and so on. Eddie currents also induce magnetic fields.
Many doorbells are based on the principle of making a magnet by an electrical current around a piece of metal.
It all INTERACTS in a complex soup. I say eddie currents but
in the broadest sense. Strictly speaking eddie currents labels only local circular currents
So for instance a vibrating resistor will create an extra minimal current if under a (dynamic) magnetic field. this extra current will be 100% "toned" by the tone of the mechanical force controlling the resistor (= vibrations by air and pcb)
Consider the whole pcb to be a moving grid with multiple nodes. Nothing is static, all the nodes, connections vibrate, the whole pcb vibrates. But the heaviest mass
dictates the nature of these vibrations (tone). That is why the heaviest mass must be the wood, mechanically coupled to the pcb.
Where do the vibrations in amps mostly come from?
From the air in the room unless you are so naive as to put the amps on top of the speakers or the speakers on the same shelf as the amps and source.
The magnetic fields and electrical fields are not uniform but do interact with each other.
These minimal currents are amplified in the amplifier as well and they are not separated noise as if in a different plane but are fully integrated in the musical signal itself They tone the music, you don't hear it as noise. This tone is extremely important and proofs empirically by hearing that eddy currents maybe
very very small in measurements but can be heard as tone
very easily. That is why Altmann insists that the wooden board directly under his amp and dac are necessary and are an integral part of the design and cannot be removed or else you loose their magic for a great part. That is also why he detests cavities inside amp and dac enclosures. these cavity resonances add ugly "tone"on top of the above story. They negatively impact the "openness" of the sound.
Another hint is the effect of dampers under sources or amps. They only damp vibrations and resonances and nothing else . Why can you hear their effect so easily? This has nothing to do with microphonic FB. Microphonics is of a much much bigger voltage and current levels
I give Altmann right. The effect I hear is
very much more pronounced than differences in IC's or even power cleaning.
It is in the same league as the difference between tubes and SS. Once hearing the difference i cannot go back. . I am convinced if end transistors like in the AKSA or lF would be cooled by copper or even better special designed pressed carbon heat sinks, the sound would make a big leap for the better
Too much however, too much vibrations even with wooden tone, add cloudiness and robs the transparency and focus away. Just like salt in a superb soup. The salt adds to the soup but too much will rob the soup.
The wood resonances somehow "correct" the ugly metallic "default" tone of eddy currents. as eddy currents are created by metals
btw the choice for wood is of course NOT meant to dampen the vibrations. but to use its resonance properties. damping is apart from it. For instance add mass and special gadgets for damping like special feet. But be be carful with heavy damping sheets l.They may not be too heavy relative to the wooden mass or they add their own UGLY tone.. ( closing the sound in and introduce something that robs the live likeness high end turning to hifi) )
