I see you like ohmite metal devil...so do I!
Don't tell me you just had them in your junk box

What's that funny looking star on the bottom right of the board?
The GND? Does it really work better with all those tiny wires, really?

You can lead a horse to water but you can't make him think. You're welcome for the gratitude you have shown for all my efforts to explain this subject.
I guess I am one that like to simplify things and only read the short answers...Sorry.

When lecturing on a subject it helps to know more than your audience. Try it sometime.........
I figured this was where I went wrong.....my post was really to offer my practical experiance of oscons...they can be used succesfully for analog as well.

btw I do but as you clearly figured not on the topic of caps or any other technical topic for that matter.......

Ignorance is bliss....

No and not on the board either...... Those are Corning RN60Ds on the board. A favorite of Conrad Johnston on most of there stuff in the past. The spider looking wire is a single point ground scheme.
For real single point grounding, having a seperate return to a single node is the important thing rather than just low impedance traces that still might carry several ground return currents through a common impedance.

"Ignorance is bliss...."

But the Truth will set you free!

I too continue to look for measurable data that correlates with sound quality. A hopeless task in some cases, but it never hurts to wonder.

Fred my mistake, I have two types in my drawers and I keep getting their name switched, pretty easy for me to do even if they have RN60D clearly printed on them.
Anyway I like them both.

Question Coupling capacitors for digital audio

I am currently working on a zero-oversampling DAC.
By reading this thread I have gathered that for decoupling purposes ceramic is best for digital (probably COG is best). The high lead inductance accompanying film and foil capacitors makes these poor with the very high frequencies involved. The noise associated with ceramics is less of a problem when used for decouping.

Is my understanding essentially correct?

What I really wish to know is "What is best type of capacitor for coupling digital signals?" I am working with frequencies ranging from 44 Khz to 100Mhz in some parts of my circuit!

Some people say 'silver mica' is best- but these capacitors become quite bulky. Is there an alternative? Will ceramics or polypropylenes do?

I found, like others may have, that the link given no longer works;
Therefore, I have attached an archive link for those who wish to read the info:
