325是輸出延時,這個可不要嗎?
只有326 ,沒有328的。
NA729:Time-Aligned input buffer boards:留著(這是32.5升級為72的重要模組)
請這個主要是作什麼用的?
那按大大的說法只要321 ,729就行了,是不是?
輸入——> 729 ——>平衡、音量 ——> 321——>輸出
325是relay線路,可以避免開關機突發低音,也可以留著保護喇叭‧我以為你只要留最簡單的,Aligned input buffer 引用NAIM官方討論區網友說明如下:
This subject has been discussed a few times here before and Tony has indeed mentioned it. The major difference between the 72 and 32.5 is that the 72 contains time aligned buffers, but the 32.5 does not.
In my experience, the result is a difference in sound presentation, in terms of timing, immediacy, sound stage depth and realism. In the case of acoustic music, say an orchestra, the 32.5 gives a deeper sound stage, with different instruments at different distances behind the speakers. It gives more of a sense of 3-dimensional space as it is easier to hear instruments interacting with the acoustic of the recording venue.
The 72 gives a more immediate and compelling (exciting) sound, with a much better sense of timing and detail. It is usually easier (in comparison with the 32.5) to distinguish between different instruments and what they are doing individually. However, the sound stage is brought forward, with instruments appearing to be mainly in front of the speakers, with a shallower depth plane (the wall of sound effect). Upper tonal registers of instruments are also changed, for example, a harpsichord sounds more wooden than metalic.
In conclusion, the 72 makes you want to keep listening, while the 32.5 is more neutral ("natural") and makes better background music.
