Another test with the cables between the CD drive, the converter/preamplifier, and the power amplifiers was technically not possible. The interconnect cables have hardly any contact with surfaces in my setup and do not touch the wooden floor. After the experiences with mains power and loudspeaker cables, a third attempt anyway seems to be rather unnecessary – what we heard leaves no doubt. From my perspective, it's pleasing that Audioquest doesn't go for expensive materials and glamour here but offers a practical solution that largely rids the signal of the "electric fog." You can certainly imagine what the Fog Lifters effected when both the power cables and the speaker cables were lifted off the floor simultaneously.

Even though measurements are usually not a topic at Hifistatement, I would like to describe one I came across during my research that you may be able to try out yourself. All you need is a millivoltmeter with a sensitive AC voltage measuring range. Do not connect the speaker cable to the amplifier and only the positive wire to the speaker terminal. Connect the cable's negative terminal to the positive terminal of the meter and the negative terminal of the meter to the ground of the wall socket. Now, if you raise the cable from the floor to the height of the Fog Lifter (around 15 centimeters), you can read a significant change in AC voltage. Here it was 1 volt to 0.1 volts, a change of ninety percent.
