Thanks Mark!

Many thanks. Enjoy the noise reduction.

... I'd hoped to see a reduction in noise as measured with the Entech Line Noise analyzer. I plugged the analyzer into the circuit with the Hydras removed and set the gain to 100. I installed the Hydras and powered everything up. I checked the Entech in the amp outlet and the noise dropped ~2 points. I plugged it into the Triton and it was the same. I then plugged it into the front end outlet and got about the same reading. It seems pretty bizarre not to see any measurable improvement. I did not pick up any AM, so that's a good thing I suppose. I also ordered some ferrite beads that I can clamp onto the 10awg Romex that might help reduce the noise floor more.
Fwiw, those are not ferrite beads slithering around in the Python. It a proprietary Shunyata compound that is, or is similar to their proprietary ZrCa2000 and tuned to absorb non-musical energy in the megahertz and into the gigahertz ranges. Irc, Shunyata believes it is clearly sonically superior to ferrite beads.

With regard to measurement testing ...

There is an interesting post from Grant Samuelson about using the IDEAL SureTest analyzer to measure Shunyata products on a different forum (Whiskey Bravo Foxtrot) - a direct reference to which here is VERBOTEN. There is also a lengthy thread named "Measuring power line noise with the TriField EM100, and the impressive effect of Shyunyata products" on the same forum wherein the Entech device is also discussed. I believe you know where this can be found if you've not seen it already.

Tim,
Thanks for the correction—I knew the beads are not ferrite, but had just clamped ferrite beads on Romex and guess I typed too fast without thinking. By the way the ferrite beads on Romex did not have any measurable effect on line noise.

In addition to the Entech line noise analyzer I also use the Ideal analyzer to measure instantaneous current capability.

I’m familiar with the other forum thread to which you refer. I bought the Entech rather than the TriField based on a statement by Caelin that the TriField is not sensitive to a noise band that is detrimental to audio while the Entech is.

Tim,
Great review! I had not seen this. Thanks.
