請教地盒構造

"等同問個地盒MAX可以食到幾多A電, 要搵儀器度囉~"

Good question.  如果唔知道,就只能當飛水綫般看待.  有冇人有地盒spec ?

"我反而好奇師兄點解想到要二㨂其一"

一就係接地盒唔接真地, 二就係接地盒然後接真地, 師兄是否有其他更好方法 而無需二揀其一?

是否我想錯, 地盒只供機身接地? 電源綫水線不接地盒而是接 wall socket?

係,  飛地線而只玩地盒係極其危險, 尤其當唔係太識玩電的時候就梗加唔好。

其實KING SIR編文已經有部份解答:

地盒並不能代替地線的功能, 只是其中一種把干擾帶離機身的方法。

我試過用竹盒倣外盒

我覺得用橡木實木盒會好一點

Thank you very much, it is very useful to understand 地盒 is only improving the circuit ground performance.  Not related to the safety AC ground.

A very similar product from Japan in this space. would be RGC24 by Acoustic Revive.  But it is much more compact.

Instead of using bulky "地盒", there are "Grounding Control Devices" which is much more handy.

There are a lot of discussions in forums.

I found a good summary by Audio Sensibility who produce it as product.

I have ordered it to try.   So it is  "地盒" without  "盒".

我部denon2313本身IEC尾座係沒有水線針位，
那樣在不知情況下玩地盒係咪好危險？

Tried the Audio Sensibility Ground Device today. I left it connected for 2 days let it stabilize first. The I did A-B-A comparison and it worked very nicely with my Wyred4Sound DAC2 DSDse . With this micro ground device, there is good improvement in dynamics and the image is more 3D. I like it and going to buy more and try on other component .

The Audio Sensibility ground device is the little "pig tail" in the middle.

f you have a fine-tuned system and want further improvement with little money, it is highly recommended.  I suspect if your system is not well optimized, you may not hear the improvement as there may be other performance bottleneck.

I recommend it as it improve fundamental performance of the DAC with improved circuit ground which I don't have any other tweak on hand.

I'll order more and try it on preamp, power amp.  Will report the findings.
