Assistance please with proper use of TI Shield

Posted by cdc (A) on February 28, 2007 at 19:20:26

The Asylum forum has always been a wealth of information. I have the bug again to upgrade and tweak/improve my gear. In the last few days I have read for hours and hours and the TI Shield posts from several members including John Curl and Alan (audionutge) really peaked my interest. All of my gear is by Proceed and I also have custom built isolation transformer units (for the front end) that I would like to mod further with the TI Shield.

I have some specific questions and any info would be much appreciated! The goal is to improve the sonics by eliminating as much EMI and RFI from the gear and system as possible. Here are the questions:

* Aside for transformer isolation devices, is this tweak also recommended on transports, DACs, amps, preamps, passive Xovers or power cords?

* As I understand it, the TI Shield is conductive. When you wrap the transformer, is there anything that should be placed between the TI Shield and the transformers? How about on the outside (otherside) of the TI Shield to protect the other electronics near by from contact/shorting? I am not clear if the TI Shield is actually coming in contact with the transformer.

* I have experimented with ERS cloth. The ERS cloth can actually degrade the sound if not really careful. ERS cloth does next to nothing in my system if placed above and or below my gear. Also no effect what so ever on my power cords. Only effect is near my passive Xovers. Does or can the improper amount of TI Shield effect the sonics?

* When wrapping a toroid transformer, should the entire transformer be wrapped, or just above the transformer? Also the amount of the TI Shield to use, same size as the transformer, twice the size, etc?

* When grounding the 12ga. wire, I read reference to "earth ground" and "chassis ground". Earth ground and a localized chassis ground within the piece of gear is the same thing isn't it? Or what am I missing?

* Any other recommendations, especially from members that have had success with the TI Shield or other similar tweaks while I am inside the gear that I can employ or try?

Too bad I cannot just hire John Curl or someone of his experience to just come to my house and do the work! :o)... Thanks in advance for any info or recommendations, it will be much appreciated!

Kindest Regards,

Chris
