Someone said that placing a piece of sorbothane on an op-amp made the sound much better.😱 :clown:
I'm still laughing.😀

Hhaha...me too. Fdegrove- Considered it. Given how hard I shook it, I can't imagine that it matters. All I was arguing is that $100 golden pointy feet won't make any audible difference....same goes for placing sorbothane on an opamp...or using a copper heatsink instead of anodized aluminum...this *@#! makes no difference.

Noooooooooooo!!!😱
Try it with the hammer!:smash: :clown:



Try it, it's nasty.😉


Haha, I'll leave the hammer test to someone else. I realized that people may not know that "nasty" now means good in young adult (oh crap! I'm almost 20...getting old! That's .5 of the way to 40!) slang. 🙂 Looking forward to construction...

What is it you think I considered?
Sorbothane on an opamp?
Who does not hear any difference between conductors made of copper, aluminium, silver or gold? Oh...I see...That was you too.

Maybe one should first learn to read what is actually written before one comments?

Cheers, 😉

The spikes is a different matter, it may make more effect on CDPs, but sometimes worst.:clown:
To reduce the vibrations you need a soft material (sorbothane, rubber...), with spikes you tune the vibrations.
Incredibly, sometimes it gets better.
No one, as far as I know, can explain why.
Why spikes or cones are better for THIS device and not for the other one.
Only testing you know.
Yes, this is still black magic.

As for the heatsinks...
I think it's just a difference of the cooling properties of each metal, copper dissipates heat better than aluminium.
So, what you may listen is the sound of the component working at a lower temperature.
If it's possible to really LISTEN to the difference, I have my doubts too.

Its based on engineering. I havnt spent much time on resonance dampening /- cancellation, but its not all that complicated as far as im concerned....
Magura🙂

Can you explain the existance of spikes?
Shouldn't you try, for instance, to isolate your speakers/supports from the floor with something soft instead of spikes?😕
And why on some CDPs spikes sound better than sorbothane?😕
Engineering?😕
 
Hi,

What data?

Data such as structural rigidity of the CDP, mass, resonances of the structure etc. Same for the surface it is placed on, etc, etc.

IOW, what may sound good for your system isn't necessarily good for someone else's. The art being to find a compromise area that's likely to be fine in most situations.

Shouldn't you try, for instance, to isolate your speakers/supports from the floor with something soft instead of spikes?

When you want to write a letter, do you put the paper on a pillow and start to write or do you put the sheet of paper on a table?
IOW, under the most common circumstances you'd want to couple the speaker to the floor to give it a solid point of reference so it can throw all the energy into the room.

Subwoofers dancing across the living room may be fun for a while but I doubt they'd be very effective that way.:whazzat:

Cheers,😉

Fdegrove-
I considerd what you mentioned above with regards to the body being able to absorb vibrations. Maybe one should learn to understand what is actually written before commenting? As my professor says, "Think twice, act once."...oh, and learn to be polite. That's another one he likes to throw in there. With regards to hearing the differences between various wires, of course some conductors will sound differently than others...a rusty nail will not sound as good as normal wire. All I am saying here is that you reach a point of diminishing returns very quickly. Maybe you should read/understand before assuming thing about what I said. Afterall, Fdegrove, when you assume, you make an *** out of u and me.

That's what I'm interested in too. A PCB with good layout for the regulated / buffered gainclone.

I'm willing to try the method I saw somewhere on DIY of using my laser printer to make a mask for the board. Perhaps that is more work than it is worth tho.
 
A PCB with good layout for the regulated / buffered gainclone

i/we have such a pcb ready, its expected delivered from production next week.

it's for the lm3886 and lt1083.
but no buffer because it's better to make a dedicated buffer pcb.

the pcb includes all - just add the trafo.

i will finnish the pcb with all parts and post photos.

then we will see how big the interest is........🙂
