Jon Risch AC Filter (Recipe 1)試音報告
Filter 整好煲咗一晚後試音, 聲音有點侷促,音量好似細咗D, 但已聽出其得出色之處: 就是空間感和樂器的演繹突出過EMI filter。當然要再煲,經過三日兩夜, 今晚用平時音量去測試這filter。
牆插到Filter: Neotech 三兄弟UPOCC 線加Duelund 銀箔雜交線。 Filter 去火牛: Neotech 24 awg 單枝銅織線

小弟的聽感, 可由以下的copy表達:
REVIEW: DIY by Jon Risch AC filter according to JR Power Conditioner/Surge Protector
128.112.152.6
I made this filter recently. It had an amazing effect on my system. Before I used the filter, a lot of sound seemed to come **from** the speaker, instead of being presented as a spacious soundstage. An hour after I plugged in the filter, the speakers seemed to disappear and there was a wonderful, enveloping sound with different instruments clearly defined in the soundstage. When listening to the symphony, I could detect the strings, woodwinds etc quite clearly and in the right places. This was the effect I had been aiming for, since everybody says that the Totems are great for imaging and soundstage.
簡單而言: 音樂立體咗, 其內涵更豐富及變化多咗, 背景寧靜咗及分析力超勁。 聽 現場錄音貝多芬第九第四樂章, 以前有四下觀眾咳聲, 今次能夠聽出微弱的第五下!羅文情繫佛羅倫斯的 " 楚歌", 之前分享過換上 RC network後聽到開頭有輕微小提琴的彈撥聲, 然後到" 叮"一聲。 Holly, 今晚所聽到的是完全清晰的演奏{:1_351:}, 原來係咁樣嘅!人聲就企出之餘,唱腔的演繹運氣收埋不了{:1_351:}
這隻值約港幣千元(連埋Oyaide插)的土炮Filter跟 PS Audio Ultimate Outlet 比比又如何?日後再分享。

其實AC filter 原理都差唔多, 但價錢可以差別好大。自己識DIY, 過癮兼慳錢{:1_352:}

DIY AC Filter : Recipe 2 (Silk 230 AC Filter by Lukasz)
這隻 Filter 煲了個幾鐘後開聲, 心裡笑了出來,立刻上來向各位放一D毒分享{:1_330:}
Jon Risch 的 filter 一出, 有不少人複製。 Lukasz 是其中之一,並加以改良。 其網址如下,其論點及功效, 有待各位自行參詳:

其主要跟Jon Risch 最大的分別是教人自製電感, 並在地線也加上電感; 所用的電容值與Jon的差不多。 小弟就地取材,用一段仔撿來的螺絲釘做DIY電感的ferrite rod , 從鐵通鋸出的圈當ferrite ring 用:

寶劍贈烈士
原本打算用木盒裝此一filter, 但又不想鑽窿, 倒不如借用 古河RTP6 的殼, 給予Lukazs filter{:1_253:}

http://i2.photobucket.com/albums/y25/firebird/AC%20Filter/DSCF0006%201%20-%20Copy%20-%20Copy.jpg
由於RTP6 空間有限, 花了頗多時間去整, 但終於完工:

稍後才料封好D窿:

Lukasz 坐在 Jon的背脊上, 照用返同樣的線:
http://i2.photobucket.com/albums/y25/firebird/AC%20Filter/DSCF0019%201.jpg
Lukasz 說要給它 24小時煲煉, 怎可等。。。
第一感覺D聲近似 Jon 的, 但聽多幾首曲後。。。。已可找到分別。。。。
已是晚上九時, 一於煲通宵,明天跟各位分享分享{:1_253:}
