Null test - you play sound 1, then sound 2, and subtract one from the other. If you end up with zero the sounds are the same. Example here shows that all cables (let alone new vs burned in versions of the same cable) are the same: https://audiofi.net/2019/01/audio-engineer-claims-his-null-tester-settles-the-debate-on-wires/ |
By Helmholtz acoustical science which he contributed greatly to found , only a few inches straw can transform a room in an acoustic paradise or in an acoustic hell... A single straw can make a costly amplifier sound bad and a bad one give a better result... Did you know that after installing hundred of systems? I installed only mine and i learned that.... Do you know the cost of a straw? Peanuts.....Sometimes what is important is not the branded name of the amplifier and his price, but the precise lenght and location of the straw....This is my first lesson in acoustic....It is free😁😊😎 What you call useless "tweaks", useless costly secondary addition to a system are in fact SOMETIMES essential devices making the system able to work at his optimal peak... The only problem is that many are too costly for me... I decided to create mine.... I called them controls over the 3 working embeddings dimensions of a system... I never bought anything, i sell nothing, i created all my devices homemade at no cost...My 500 hundred bucks system fill my room 3-d with imaging, encompassing listener soundstage, natural timbre perception, in 2 main listening positions...Is there better one? Yes, but i will let you guess their price....It is not 500 bucks....It is the embeddings controls not costly electrical design ONLY and MAINLY the road to a good sound.... Am i hallucinated? Am i a liar? For some here deluded by dogmas probably... It is not the PRICE paid who give us good sound , it is the way we are able to control our system, the electrical grid, the vibrations and resonances, and tune the room... Some people are incredible and even repeat here that our ears must subordinate their power to any objective number they will see on a dial....If they are doctor they call ears impressions " illusions".... And incredibly they listen to their system and call what they hear "good" because the equalizer said so..... I will mute myself astonished by human voluntary blindness because of sheep walking..... Dont buy and dont plug and play no more, be creative think and listen ..... Dont upgrade anything before everything is rightfully embedded in his 3 working dimensions and under controls... |
