For #1, since the high current outlets don’t have the noise reduction filter

Hi sam1000 this isn't strictly correct. Not many know this but the QR/BB module that feeds the two outlets in zone 3 (HC) actually sits inside an NIC module (filled with ferroelectric crystals) and therefore offers noise reduction. I saw this at the factory this week. You also have the CCI filter mounted directly behind the two HC outlets which contains proprietary multi-stage filters. In addition the Trident surge module includes noise reduction circuitry and this interfaces directly with this zone. So there is quite a bit going on!

You also have the proximal effects of the med filters in zone 2 and 3... I have demonstrated this effect by plugging an Entech noise analyser into one outlet of a duplex and then connecting a Delta NR into the other outlet of the same duplex. This generally shows quite a dramatic fall in the numbers recorded by the Entech.

The benefit of going with an NR cable is that you are zapping a good chunk of the noise at its point of inception, with some of the rest travelling to the Denali to be addressed there. You can never completely remove noise, you can only reduce it by a factor. 

Cheers,
