How important is EMI and RFI rejection?

"The much pricier Tripoint is what I call grounding on steroids and worth the price of admission."

Darn...I was afraid somebody was going to say that...

I don't doubt the Tripoint is better. I know Miguel and he has been playing around with grounding schemes for a while. I don't doubt he is on to something with the Tripoint. However, not everyone can drop $8k on such a device. As Danmyers said you could do it a lot cheaper and get good results.

Then again there are people like Charles Hansen of Ayre who have a totally different view on grounding.

OK, I'll bite :) Where can read up on Charlie's view of grounding? Thanks!

Go over to Audio Asylum. Do a search there. He's posted his views many times. Ayre uses double insulated chassis' in their design so you can float the ground without the danger (according to Ayre anyway). Charles also lives in an old home where none of the outlets are grounded. I believe he floats all grounds in his system.

Here's on thread where Charles comments:

Based on what they're experiencing it appears that floating grounds has similar sonic effects to the Tripoint.

I have found that on my system that consists of Magnepan speakers (20.1) Krell FPB 600 amp, Accustic Arts DAC, Sim audio moon eclipse cd player(used as transport) BAT 52 SE preamp, ps audio power plant premier(ac to dc to ac generator)dedicated breaker box, shielded ac wiring,dedicated sockets, 6 foot ground rod in the earth,that I could not live without cables that were not efi sheilded. When you get cables that are well shielded you will get rid of a glare and blanket of music robbing junk. I use Purist Audio Design cables exclusively. If any one tells you they don't make a difference in performance then they sould talk to NASA and see what they say about EFI and EMI. Better yet do an A,B comparison and you will hear the music come alive. I have enjoyed the improvement for years now and no one can tell me after all the improvements that noise does not enter through cables. Just by nature they are antenas. Also if you want to hear another product that gets rid of EFI andEMI by the power of ten then check out Tripoint Audio you will be shocked.
