Copper Shielding of Digital Chips?

[fastcat95]

Hello to all!

Does anyone have comments about using copper shielding
on top of digital chips in DACs? Is there a worthwhile sound
improvement? Should the copper be grounded to the circuit
ground, or to the 3rd wire earth ground coming into a DAC?

Many thanks in Advance!

I have never tried this trick with a dac, but have had success covering the tripath chip in my Amp6 with a copper shield (grounded to chassis ground).

Subtle improvements in smoothness and detail.

Worth a try...

If it works, it does something for very high frequencies, hence the copper should be grounded very close to the chip (ground).
