casing about SOHA I headphone amp

[yhong]

hi new member here...as the title,now i own a SOHA I with aluminum metal case. Anyone here try to used wooden case? It will be any different if change to wooden case?

[singa]

hi, Why would you want to do that? Too much money?
Unless you have golden ears I doubt you will get much
milage or improvement from changing to wood box.

Is it a mind over matter kind of thing? Most people
would not care what material they use as long as it's
the normal or conventional or convenient.Aluminium is easy
to work with.

There is a case to use wood (hard wood) if you believe that there
are secrets of reality or universe.It is very interesting
subject that many are not aware of what makes up
reality as we perceive it and what constitutes the space
and solid matter.Scientists and quantum physics explore
these realms and they know things that normal people
don't and they are not about to tell because even among
their fraternity there are conservatives that "maintains"
the status quo as it will turn conventional scientific "wisdom"
on it's head.Just too radical or far out to accept for now.

Ok just to whet your curiosity,do you know what is a fractal?
Reality is full of it.Enjoy the journey to truth.

Haha.
very good way to treat a new member.

If you simply wish to build it in a wooden cabinet for asthetic reasons, go for it. Just use an al plate for the top deck to give you a good ground plane above the circuitry.

Otherwise you may wish simply to add wood to the al chassis like done here:

or, in my case, I had time and materials lying around
best of both worlds, definitely look & sounds better than breadboard

Like I said it's too far out for most people.I did not mean to
make fun of people but offer a esoteric perspective of reality.
Do your research and find out if it has substance or not.

Let me ask a question...Why are violin and string instruments
made of wood? That should lead somewhere.

Looking good! I noticed you have the same antique CD player that I still have and occasionally use for testing purposes

Oh boy...it may have something to do with aluminium not being available when Guarneri and the likes were building them, and yes, wood sounds better (I played a violin made out of brass once. It sounded just like you'd imagine: like a cat being brutally murdered inside a metal workshop). But comparing a musical instrument in which the material of the body is an inseparable part of the sound producing mechanism to an amplifier is a bit far-fetched, no? And I'm all for the esoteric stuff, believe me. Anyway, let me put this one back at you: how would you describe the difference in sound between an amp in a breadboard configuration and exactly the same circuit encased in 10-years cured Italian pine with mahogany trim?

[yhong]

some electrical violin does't make it with wood also,because wood elastic?haha....
but for sound,why many people prefer wood like wood can....
but may be will no effect will the electronic product,i don't know?....haha...
but for DIYer,this little change will make it interesting ans happy....

Thank you for attempting a reply,at least you put in the effort!
Apart from being a good tone wood that is they are efficent vibrators,
they share something similar to humans and that is they were once
alive or organic like us which kind of makes us kindered folks.Hope
this is a satisfactory answer.Yes aging of the wood ,all parts does
make a difference(including the glue?).That's why violin newbies are advised to go for
something made at least some time back rather than fresh of the assembly
line but then again good violin makers would have left the tone wood to
dry and age as well.

As for the first part yes it's pretty esoteric but as you know if it was just
an audio circuit a breadboard version may have little difference compared
to a RF circuit.Circuit elements L,C,R come into play not that it does not affect audio as well but not so critical unless you are a die hard spice circuit
simulator.

That was my main purpose but if you dig deeper the answers are there.
Rather than the standard reply that does not push the boundaries or as to put
it "maintains the status quo".

yup, that discman of the early 90's, I can't help my self laughing when my daughter said i'ts kaput, turn out she put mp3 cd in there .
will be cool if we can somehow make a spdif out of it, no?

happy easter
