Hard wiring is the ideal connection, but not everyone is comfortable ripping the cable open or drilling holes in the chassis to mount the choke. This offers a cheap alternative, especially if you are looking at installing parallel filters close to the component. The quality of the iec connection is no different than what you see with the 320iec to C7/C8 adapters. I haven't experience any loss in sound quality using the jumper...the choke is strong enough to make the connection disappear.
I have no idea...I do not use the speaker filters/nor have I built them. I mentioned the TI Shield because it was something I used in the past and happen to like. I use it for shielding and damping plates when combined with 1/4" microsorb. TI Shield offers superior frequency bandwidth and noise reduction compared to copper. But in all honesty, I think you are making too much of an issue out of the shielding. It's the earth ground that is important...not the shielding material in this application. TI Shield should be used in a single layer.

Alan, I'm trying to understand both theory and adaptation of the concept. I grasp the shielding concepts and can fathom that TI-Shield is superior because of the ferromagnetic layer in the copper sandwich and how grounding it adds that EM shielding effect to the regular copper's RF shielding effect.

Personal thing, but I like being able to go to the local hardware store, instead of having to order and stock specialized materials from distant sources. Was just trying to figure out if there was a simpler alternative available than ordering TI=Shield, but if the superiority of the TI is that much, then I'll just bite the bullet.

Since I've been experimenting a lot with R-Cs for AC filtering as well as speaker cables, I'm curious about all the potentials of similar materials and configurations.

  As long as you clean up the copper and play with the size of the earth ground you should be fine. Keep the ground anywhere between 14ga and 8ga...I can't be anymore specific because the rest depends on the system interaction to the shielding.
