How important is EMI and RFI rejection?


In designing a cable....and what cable manufactuer(s) excell...

Power cords
IC's
Speaker cables

Have you tried putting a ferrite core around the power cord and interconnect ends right where it plugs into the equipment? You can try it very inexpensively and will block all RFI from entering your system, no matter which cable you are using.
Proper design in cables alone will not completely get rid off EMI noise and in some cases even RFI. This is because so called high end audio components today are not built properly, poor grounding, poor shielding etc. Yes, you want to have good qiality and properly designed cables that will help not introduce more junk into the components but most components will inherently have some. I was made aware of this when I started looking at properly grounding my components and was further astonished when someone introduced me to a passive filtration device called "Troy" from tripoint audio. After grounding my amps, preamps and Turntable to the tripoint audio box, the level of darkness, clean upper frequencies and just overall space and music flow was jaw dropping. I am an importer/dealer in the South Florida area and I invite any of you to come by and listen to an A/B demo.
Just took a look at the troy.....interesting product. I counted up what I had invested in cables the other day,,,about 12k. The Troy is 8K Scudi....gulp....Hi end for sure.
Fvcruz,

After reading the Tripoint website...

"Come experience the holographic transportation of the real musical event with our proprietary passive filtration that eliminate EMI/RFI from the signal and impulse signal flow. Hear what your electronics, room, and vibration control really sound like."

My preamp a accuphase unit is very well made and shielded...also my Vac 140's have a 3 setting ground adjustment that produces a noticeable improvement in transparency and blackness along with a holographic soundstage.

Thanks for pointing out the EMI/RFI connection to grounding...

I might have to consider a troy someday....
