除左真係好D

帶套寧願唔玩~
試過就知唔帶好feel好多

我剩係知除左個套，二手價會差左……

這些所謂放，動態加強的聲音，其實是RF/EMI的干擾noise所發出來，不要也罷。

Despite the theory, 都係耳聽為實!

I have done the experiment in my system yesterday, comparing the the result of using Cardas RCA Cap, Audio Technica rubber Cap and No Cap at my Pass Labs XP-20 Preamp, just using Track 2 from Akiko Yano / Home Girl Journey SACD as reference. This Album recording just have Akiko's vocal and Piano, the recording is superb in quality, pinpoint position, extremely airy and spacious sound stage, the vocal full of details of and 3 dimensional imaging of Akiko, it is my reference for testing the component reproduction of Airy sound stage, extent of treble and female vocal.

I have been Cardas cap for more than a decade, it does have positive effect to my Audio Research Pre and Power Combo with darker background, every note sound more smooth and refine...........but after I changed to Pass Labs Pre and Power combo, I noticed the Cardas cap limit the treble extend, the sound stage became less airy and spacious and shallow. I replaced all the Cardas Cap to Audio Technica Cap have gained back a little bit "Air" but it is still less Vivid, Lively with a Holographic Sound Stage comparing to "NO CAP" at all...........

Putting cap the RCA connectors (3 ONLY) on my dCS P8i Mk2 CD player have less negative effect, but limit of treble extent can still be noticed.

用與不用，只要自己覺得合適便最好，George Cardas有段片在youtube示範用cap的測試，一個簡單的測試已經說明用cap的好處，但若果在自己的器材內使用了cap之後，發覺高音少了，聲音不夠生猛，這代表了什麼?
少了干擾，即反映了你系統的真實表現，高音少了，不夠生猛，正確的解決方法是否應該搵出問題所在，不應該用'一種失真去掩蓋另一種失真'來取得平衡，當然若喜歡這種聲音亦無可厚非，玩音響都係為給自己聽，最重要係自己喜歡。

值得注意一點Cardas XLR cap 將XLR嘅pin 1 signal ground連接機殼 (chasis ground), 有可能已改變原機星形單點落地點設計, 變爲多點落地. 大忌!  
任意改動或增減落地點, 會影響動態表現.

I would say if the component have very low noise floor and the designer have counted the interference of RFI/EMI in the first place, using the Cardas Cap may result in such "Masking" effect, limit the treble extend and cut off the harmonics of instrument......

As told, I do have good result with Cardas cap with my old Audio Research Pre and Power combo (LS-15 & VT-50 in balance connection) before, but it doesn't work well with my Previous Music First Passive Preamp, and my Current Pass Labs Pre-Power combo which have lower noise floor. The logic is very simple that if not using the Cardas cap have better extend of treble, more airy and spacious sound stage and vivid........the reason is that the Cardas cap is "over-damp" the component and lessen the second and third harmonics resulting of less airy sound stage and linear extend of treble.

There is no right or wrong, recent audio component have better design and resistance to interference, that is why these components can not benefit to the Cardas Cap. The Cardas cap was introduced in the 90's, the audio components have evolved and improved a lot in terms of S/N ratio, linearity, capability of reveal the inner details in the past two decade........

鐵兄,
RCA cap嘅改變難以用理論解釋, 但音響電路設計涉及多方面, 解決一個問題同時引起另一問題也經常發生.  
所以如果多人聆聽後都有類似結果, 有一定參考價值的.

除左真係好D.
