RE: DIY Detail Magnifier

Looks good Marvin. Glad you found the DIY. I owe credit to Al Sekela who first deconstructed Walkers High Definition links. (I believe) Some others questioned the values but the .01 and 10 ohm resistor have always worked best for me. I've tried many other values.

Second I found silver wire and spades improved things and cryo too makes yet another level of detail possible. As good a cap and resistor as you want is always best. I like the Allen Bradley mil spec 5% carbon resistor in all my tests. There are many many caps out there to try.

Enclosing the R/C circuit in a shielded body helps but I found (via a tip from Al) that a drain wire to ground from the shield was not good.

FYI the purpose of the circuit is to remove RFI that naturally rides along all wire and as it is in the Megahertz range we can try to eliminate it w/o touching the audio signal. This in turn allows for better transfer of the signal from the amp to the speaker. It improves all parts of the audio spectrum (w/HF the easiest improvement to hear) and improves image and sound stage.
