各位

重有一樣分享, 其實不單只cd 有正反相錄音, 有的前級 及 dac 都是反相, 好驚唔驚 ?

舉例: lite dac 60, 及 Rogue 99 是反相

但如果 以上 兩個 反相一齊用, 又可 負負 得 正.

That's right. We cannot guarantee each equipment is in phase itself. Just the sound output is in phase is ok. But that requires golden ears to know. :(

如果肯花心機每隻cd正反相各聽一次,應該好易分到,

Many DACs have normal / inverted phase button.

If any one can hear the difference by pressing the button I cut my head for you to seat....

How many heads you can provide for cutting!!! For a good hifi system, NOT EXPENSIVE SYSTEM, everyone should hear the difference between 0 phase and 180 phase!! But...............how many guys have a good hifi system??????????

不用好的器材, 反相是很容易聽到的, 我做了一段反相的錄音, 已 upload 到 youtube. 在的的平價電腦 speaker 都聽到分別:

原本的錄音:



反相的錄音:

嚴格來講, 相位 (Phase) 這個術語有點被誤用, 一般我們講的「反相」是指 Stereo 左右兩條聲軌其中一條 Polarity 反了, 亦即我們通常講的 out-of-phase 。

patrickwong c-hing,

yes, it always confusing....
I suppose many c-hings here are talking about invert phase...


Let me clarify my position sin....

out-of-phase:
If any one CANNOT hear the difference please cut your head....

inverted phase:
If any one can hear the difference, I cut my head for you to seat....

That's the point. Yes, NOT out-of-phase, inverted phase (0 degree to 180 degree). If you are familiar with classical music, your system is well presenting the recording, you can hear this. Even though a non-audiophile guy (my wife) can hear the different. When the phase is correct, first you hear more airy from wood winds, you hear more details from violins, the position of all musical instruments can be clearly identify its position in the orchestra. Many many to prove but my poor English can describe this. So that that I don't know how to type Chinese using PC.

No need to argue and cut your heads. They are all physics and engineering. Just draw out all the graphs can prove whether different sound will be produced.

6moons.com - Fazed About Polarity and Phase ?

http://www.6moons.com/industryfeatures/polarity/polarity.html

"Absolute polarity. In phase. Sometimes audiophiles get confused. Which is which? Absolute polarity means that a leading edge is heard as a positive pressure wave or compression (higher density), not a negative wave or rarefaction (lower density or decompression). ......"

hiphopzz hing,

"inverted phase:
If any one can hear the difference, I cut my head for you to seat.."

Every time when I press the "Phase" button of my DAC, I can hear the difference.

With absolute polarity of the CD, the bass will be more solid, the voice will be more sweet and the treble will be more clear.

But you can keep your head for your own use - just joking :=)

Happing listening
