line with the quality of the recording used at that moment, its "physical characteristics" would have been taken into serious consideration, for the elaboration and the experimentation of other features with the best performances. This is because the greater "efficiency" and "speed", tends to highlight the "sound quality" possessed by the "audio signal" in transit inside a solid conductor: if it is poor, it remains poor; if it is excellent, however, it is enhanced!
11. Experimenting with "power" or "high voltage" cables
Together with the experimentation of "audio cables", but with slower and deferred times, the experimentation of solid "power" or "high voltage" conductors was also carried out, ie those suitable for the transit within them of the flow of high voltage electricity (125/220/240 Volt). The slowness and delay of this kind of experimentation have been due to my total skepticism about their impact on the sound quality of a HI-FI system. This is because there is no audio signal inside them. In the end, however, the type of solid conductors gave an incredible surprise.
11.1 First phase
In the eighties I made several small discoveries. First of all, the first was a small improvement in the sound performance, replacing the normal plugs of the power cables of the audio electronics, with others larger than 16A. The next was that the sound improved again, using more "extensions" connected to different 220 Volt electrical outlets, instead of a single extension with multiple sockets (known as a power strip), connected to a single electrical outlet. The third, the most curious, was that the cables that constituted the extensions and/or the cables of "feeding", did not have to rest directly on the floor and on the walls. Finally, increasing the section of the electric wire inside the extension cord and/or the power cord itself further improved the sound quality.
These first rudimentary experiments, at the end of the Eighties, led to the connection of electronic equipment to the mains, to the use of traditional solid conductors composed of three insulated electric wires of greater section, sheathed in PVC, and equipped with a 16 Amp plug.
11.2 Second phase
The type described above of "power supply cable", set the "basic criteria" for the subsequent experimentation of new types. In this way I have developed new projects to go beyond the "basic criteria", whose experiments led at the end of the second half of the Nineties, to the elaboration of the well-known "AL" and "PF" power supply cable projects, presented by my web journal HI-FIGUIDE© in early 2000. These, have had a great success of criticism from many audiophiles, in addition of course the negative ones.
In 1999, after careful experimentation, the prototype of "Perfect Supply©" was born, my first high performance power cable, with revolutionary technology "Trex Wired©" (TX-W©), applied to high voltage. This, in addition to recalling the "basic criteria" related to the "transport" of high voltage, has deeply innovated them. For a marked difference in sound performance improvement, in addition to establishing a surprising discovery, it introduced new ideas and theoretical development bases for future experiments.
11.3 Third phase
At that point it was clear that it was necessary to carry out a larger experiment, which would have required 13 years for its correct implementation.
To avoid "conflicts" on the results, decided in 2002 to use, on 7 electronic devices in the audio system of my laboratory:
TX-W©), adapted to high voltage; n. 4 traditional power cables, with gray PVC sheath, four insulated electric wires and 16A plug.
Therefore, until 2015, all the experiments carried out since 2002, on solid conductors destined to the transit of the audio signal, have always taken place with this same configuration:
the 3 "Perfect Supply©" cables, with "TX-W©" technology, have been placed: 1 in the digital reader and the other 2 in the two electronic crossovers; the other 4 traditional cables were placed: 1 in the preamp and the other 3 in the three power amplifiers.
At the end of 2015 it was time to carry out an important new experimentation. I have therefore made a super power cable with patented "High Power©" technology (H-PW©), in order to replace 1 of the 4 normal power cables.
According to you, dear readers, for a correct experimentation, where should this new super cable be placed? In the preamp! The results of the experiment, described below, were totally unexpected...
