如題所示,
板上近期在爭議的論點,
不外乎是主觀聽感,
或是量測不好或是不能證實等問題,
或是是否真的能聽出來等問題,
有以下想法
1.主觀喜好跟電子訊號正確不一定正相關,
因為設計是能夠設計出特地喜好的,
但是不一定是電學要求正確的訊號。
2.不違反學理基礎,太多論調不符合基礎原理,覺得消費者要眼睛睜亮,不見得是電子產
品,市面太多產品太多誇大,如果沒有真的去k過花時間學相關知識或是原理,真的太容
易被唬。
3.太過誇飾的超人類感官是有爭議的,
甚至聽過一根針在前面也能發現的,
事實上光量產ic +PCB ,PVT可能都造成硬體效能指標10%以上的差距,而且這個可接受變
異量還落在三個標準差內,量產1000台每一台都能聽出不一樣,怎麼看都不覺得合理,那
怎會覺得換了個根本影響只有0.01%的東西就會飛天了呢?
以上小弟拙見
