How important is EMI and RFI rejection?

"The way electricity works is it flows down the path of least resistance. So you need to provide a super-highway for the RF energy to travel on that moves it away from your system. If you do, you'll never hear the RFI. That is one of the main purposes of grounding. RFI has some other characteristics that we can use to whisk it away."

Take a bow Dan,take a couple. I have my super highway almost done. I did the preamp,dac, and transport, have the amplifiers to do,all four of them. Should I tie them all together and then wire to the preamp?

This has been a real humbling experience. One of my favorite Cd's is "Music from Hollywood" a recording done at the hollywood bowl in 1963. I have listened to this disc a hundred times,tonight....I don't want to turn my system off.

Thanks Dan,

Hi T,

When I'm done I'll snap some pics and email them to you. The Vacs will be a challenge I think,not too many chassis connections. I hope tonight it sounds as good as last night.

Cheers
Pictures would be great. Funny, I was wondering the same thing about how to work it out on my VAC amps.

Just another note. I just had a friend remove the ground wire from the chassis IEC inside his transport and noticed an improvement. I'm wondering if its worth it or even makes sense to mix the two concepts together: floating grounds and the chassis grounding scheme.
I did my 2 sub blocks and they have never run this quiet. After looking at the vacs closely the only chassis screws are underneath and at 100Lbs a piece there has to be another way. The vacs have a adjustable grounding switch anyway,but I would still be tempted to see if there is a difference.

Floating grounds and this treatment? You better ask a opinion of a expert. I am way over my head doing this, I can't beleive it worked and it sounds great today too. Inky black and the speakers are alive. I never thought I had a grounding problem as all my stuff looks to be well shielded.
