Metal collars around cables?

 I am seeing more and more cables with a metal band around the cable at different locations. I am familiar with the MIT network boxes. I am wondering what is the purpose of these add-on's?

 Sometimes they are a ferrite bead intended as a noise filter, but many folks find ferrite beads do more sonic harm than good. Some seem to be a stylish flair for looks only. Otherwise, most metal devices such as that are a speaker cable splitter in order to create a nice looking pigtail for termination purposes.

 I thought some might just be decorative. I have heard nickel metal is good for absorbing RF and have seen comments about putting pressure on the dielectric at certain points helping. So I wondered if there was some form of passive improvement like that?

 There's a method of cinching a wooden device or other material positioned on a cable at particular resonant nodes, but I think the Highwire Audio Power Wrap or RFI Coil is the best method to tune cable resonances as well as reduce potential noise. However, it's hit or miss when it comes to experimenting with those devices. The effects can be quite obvious, for better or worse from a system tuning perspective. YMMV

 Mike VansEvers made cables like this. IIRC he had brass washers inside a wooden clamp assembly and you could simply slide the weight up and down the cable to tune the cable.

On a power cord, closest to the IEC yielded the most treble, but I like the position about 9 inches form the end where the mid bass became lush and full. When I used ferrites, you could her the same effect with the placement of the ferrites

MIke called it string nodal resonance and it works on all cables including IC's. You can try it on Kimber's Select cables which use a wooden piece to hold left and right cables together

 It certainly can't hurt, YMMV. Ferrites are a sort of filter so the general consensus is that they are acceptable on certain power cables but are controversial for analog audio signals.
