two old mod for amy digital device. antistatic foam, and upping the AC frequency

Both of these mods came from articles in Stereophile.
Way way long ago a comment by a contributor in Belgium about adding antistatic foam to a digital device to block the RFI insinde the chassis from affecting other things inside the chassis.
Particularly effective inside DACS.
Few if any folks seem interested in this mod. But I have used it in my DAC for many years.
Basically use the black foam (not the blue) and cut to fit, then put the foam in baggies (so it does not short out anything) but do run a wire into the foam through the baggies to ground. I fill the chassis with them.
The heat is not an issue, as the device really is no hotter (at least in my experience)

Then upping the AC frequency. Raising the AC frequency going into the product improves the performance of many audio devices.
Problem is hard to find AC. The one solution I have found are old PS Audio P300 and P600 WITH an optional board which allows altered AC frequency output. (The boards are no longer made or available from PS Audio) So if you can find a PS Audio regenerator with the board installed. Then you can up the AC mains frequency to up to 120Hz instead of 60Hz. (I have no idea why no one makes a regenerator with this feature anymore??)
Again, this idea came from a comment in Stereophile.
(I have to say, as commented in Stereophile, the upped AC frequency does not work well with SOME 'digital' power supplies. but regular power supplies in digital gear work fine)

I use both of these ideas in my digital front end. They both work.
