I am planning to buy truthear zero red, but hesitant due to this inverted polarity thing. Some people say the difference is audible while others say it isn’t. Crinacle said in a comment that the difference is audible but it is subjective which sound you prefer, inverted or non inverted. That sounds so strange to me; shouldn’t non inverted sound be preferred, even if it subjectively sounds worse, since that’s the correct way to listen to music?
