Just for giggles I bought a Rdinscos “Ghostbusters meter” to find out the amount of Electrical Magnetic and Radio Interferences behind my 2 different racks.
I immediately noticed that STEALTH Dream 20-20 power cords show higher values of “E F”:
Same position, run and component fed. Measurements taken very close to the cable, 30 cms (1 ft) far from it the value is negligible or zero.
Reading STEALTH website it should be caused by flat conductors used, which reduce the skin effect.
I had a Cloude Grande as spare (waiting for the upcoming Digital Director), so I replaced the Dream 20-20 feeding my amp.
Even if totally “cold” I’m really liking it. Sound is speedier, punchy and vivid. Too early to get the big picture but very promising.
Out of curiosity, around my racks I get negligible values of MF and RF (I don’t use wifi at all in my room and my iPad is always in flight mode).
Therefore considering only “E F” values I have:
MSB components, Innuos server, PZ chassis and Sakra cables around zero.
Tempus switch, all ethernet cables and router incredibly high.
As for power cords, the difference between Cloude Grande and others (Dream V18 in particular) is remarkably significant.
So, this means one design has more shielding than the other in power cords, and ethernet cables have less shielding, I guess.
I moved satellite and switches away from the main rack and the system sounded better. But it could be due to other changes in the system. I don’t really know how much EFI/MFI affecting SQ of any particular component.
Maybe you can try wrapping tin foil around Ethernet cables to see if there’s SQ difference
I can’t really say anything about that, to be honest.
The values are almost negligible a few centimeters away from the cable but constantly high along the entire run.
It means that the rule of thumbs “don’t go parallel” makes sense.
It means that keeping well separated the cables makes sense.
It unfortunately means that the mess behind my racks, can’t help.
After a few hours listening to the Cloude Grande vs Dream 20-20 I’m confident to grasp other things hopefully. The CG cable I’m testing is brand new while the 20-20 was plugged for months.
The proximity of the Grid Protector’s antenna seems to have no impact in measurement (unlike sonics improvements).
Very interesting, and the flat conductors in the CG could cause less interference. According to Stealth, they should have the same structure except for the shape of the ladder. If the cable emits less radiation, it is also better at blocking external interference. Some use what’s called a 360-degree shield around Ethernet cables. This would be an additional braid for shielding, to which an insulated wire runs parallel, which is wrapped around the cable a few times at the ends and then connected to the shield. Are the results of measurements with and without CAD Groundbox the same? Do components with or without groundbox emit the same values? At least now you know that a Cloude Grande is the better cable and therefore costs more. If I’m not mistaken, the outer, visible conductors are just a drain wire used for shielding. Flat conductors or radio coils (like a spring- wire) are said to work better.
You can also use the Ghostbuster meter to check whether the EMI protector is doing anything. Fortunately, the measuring device is not too expensive. Maybe I’ll order one to measure and put in a drawer afterwards. Now you have made me curious about what values my cables emit. I fitted my hi-fi rack with a grounding box from Xangsane as a test because it is made of metal. I think I should order a measuring device like yours for further experiments.
Just plugged back the Dream 20-20 into the PZ feeding the amp and it took me 5 minutes to determine that it sounds better, no doubt.
Bass are rich again, spaciousness and depth are more evident, airy and realistic. I’d say fullness and articulation. More meat on the bone. Love it, interferences or not… it is my choice, I trust my ears more than meter’s numbers.
Haha I remember when ASR did a measurement once of an Audioquest cable, they claimed the measurement/result would be better without the DBS module. They never made a listening test, which would then have been very obvious. But we know what ASR is up to anyway
A while ago I asked you to compare Stealth C.G. to 20/20. I remember you said CG for DAC (or streamer?) and 20/20 for amp. Looks like you gave confirmation again.
I am thinking of a Stealth but cannot decide if it should be a speaker cable or a power cord.
When/if I ever give up listening to music with my ears and take up staring mindlessly at an oscilloscope I will give ASR a look; but until then they can take their measurements and smoke 'em.
Fear those near you in the “hole”.
