Some has disdain for solutions that dont come from them or dont have a place in their frame of mind.... :)
Not me, i guess i was an audiophile, because the most important was for me to win a good hi-fi by my own means only ( i dont have the luxury of money). And i am not an engineer....
But in audio, the engineering basic design is already mature for the last 50 years, and except some new technology, the basic design is mature, then almost all product are on a quality/price ladder with 3 rungs : low, mid, high....Even dac technology begins to be good in the last decade and affordable...
Then for an audiophile, the S. Q. comes mostly from many other things than only electronical basic information or design... Pick some good E.C. (electronic component) on this ladder and the S. Q. increase will not come from basic electronical information mainly , but from the way you will embeds this audio system in your house and room....
Within 2 years of experiments each week mainly, i create my homemade low cost solutions to these 3 embeddings problem that would seem ridiculous or worst appalling in some case for a classical audio engineer... They works marvel for peanuts....My ears said so indeed....
No measuring electronic device would have made that possible...No way....
Controls of resonance, of the house electrical grid and last but not least of the acoustic with not only with passive materials but mostly active different ways can create a S. Q. "out of this world" without any unecessary upgrade...
My principal audio discovery after my own experience, is most people dont even know what the audio system they already own is able optimally to deliver....No electronic measuring device would replace the methods i had use to controls this 3 embeddings...For sure no change of cables too.... :)
For the cables problem, yes there is difference, no they are not generally big differences, and thirdly most people listen to cables in a non controlled environment then how can they be sure that their cables is the best?...
And last, most cables afficionados put their money at the wrong place, and for that i think like roberttdid and i have the same opinion .... But his measuring proof is for me unecessary and his blind testing obsession let me cold like ice.... My ears speak louder to me about cables differences so to speak.... :)
I trained my ears to transform my own system without needing any engineer, with good basic electronic component....I succeed for the cost of almost peanuts.... I dont sell nothing, my idea are free and i dont upgrade....
Regards to all....
