The Astoria電源線
(Alpha) PC-Triple C導體採用

Furutech Astoria power cords
If you’re a musician or a recording professional, ask yourself the following question: Do your current power cords make sense?
They might make sense to your budget or in the context of your recording and playback equipment, but are they making sense to your brain? Does the music you create in the studio sound like the music in your head, natural and inviting and emotional? Or do you listen to your music with an imaginary clipboard in your lap, checking off what’s right about the sound you’re getting—and what isn’t so right?
The new Furutech Astoria and Empire power cords were designed for demanding professionals just like you. Developed in Tokyo with extensive feedback from musicians and recording professionals, the Astoria and Empire power cords have been specifically tuned and balanced to deliver greater punch and dynamics to your sound—more of what you’re hearing in your head and in your heart.
In fact, choosing between the Astoria and the Empire provides you with even greater control over the type of sound you’re trying to achieve. Pick the Astoria if you’re aiming for quick response and natural speed, mated with deep and powerful bass. The Empire, on the other hand, offers a well-balanced sound with incredible resolution so that you hear every detail and nuance. It’s up to you.
Just replace the existing power cords for your amplifiers, mixing consoles, microphone preamps and even your entire recording and playback system, and you’ll immediately hear more top-to-bottom coherence in the sound. Dynamic range will be greater than ever before, and the music will sound effortless and expansive instead of congested, edgy or muddy.
Your music will start to make more sense where it counts—in your brain.
The legendary design team at Furutech are experts when it comes to preserving the signal path and delivering an end result that’s accurate, honest and uncompromised. Our innovative (Alpha) PC-Triple C power cable, used in both the Astoria and the Empire, is the result of a proprietary forging process that involved repeated rounds of metal folding—the same method used to create the katana, the sword used by Samurai warriors!
We’ve taken that art of sword-making to new levels, however, by applying variable high pressures to high-purity oxygen-free copper. This creates a forging process that is identical to folding the steel of a katana tens of thousands of times. This ensures that the crystal grain boundaries deep inside the copper are rearranged so that electrical current travels through the signal path more smoothly than ever before.
Add our renowned gold-plated connectors, our noise-reducing (Alpha) conductor shielding, our vibration-controlling RoHS-compliant flexible PVC sheath and our patented Floating Field Damper grounding system and you’ll have a razor-sharp tool for extracting the finest results-- both in the studio and on the stage.
Use Furutech’s Astoria and Empire power cords for all your recording and playback needs and the end result will not be subtle.
Furutech 絕對稱得上是線材專家。

這世界上有這麼多音響線材品牌,為何我要特別強調Furutech 為線材專家呢?至少有兩個原因,我要稱他們專家。第一,Furutech 的產品全面且完整,有各種等級的線,各種用途的線,有成品線,有切售線,有各式插頭、端子、有各類線材相關周邊。並不是每一家線材廠商都有這麼完整豐富的產品,有的線材廠有線,但是沒有線材以外產品,也沒有零件供人DIY,所以Furutech 在眾多音響品牌裡,確有其過人之處。第二,正因為Astoria 這樣的電源線,我願稱其為專家。這話怎麼說。音響線材品牌多半標榜自己是Hi End 線材,能讓家用音響的效果提升,但少有音響廠商會關注到專業器材用線。Furutech 單是電源線就推出了好幾款特別強調是「專業用途」的線材,而且看起來都不是醜醜的、很簡單的,而是用上自家好料,打造出供專業用家使用的電源線。

為音樂工作人打造

言歸正傳。這次評論的Astoria 以及另一條Empire,就是被Furutech 歸類為專業用途的電源線,稱其為「Studio Power Series」。為什麼要推出這類線材呢?Furutech 指出,包括樂手、音樂製作人、錄音師等音樂工作者,他們所使用的音響設備也需要插電,因此,也躲不過電源線對音響器材的影響。然而,他們所製作出來的音樂作品,是否與他們腦海中所期待的一致呢?那些聲音是否夠真實?夠自然?夠能引發人的情感共鳴?如果有差別,Furutech 要提醒這些音樂工作者,線材正是其中一個影響因素,如果用上好的線材,會提升整體的聲音效果。Astoria 比起Empire 價格較低一點,不過,Furutech 也強調,這兩條線的差別不在高下,而是在設計的取向不同,因為用料不同,因此反映在價格上。Astoria的設計偏向反應速度,且有深沈有力的低頻;Empire 則提供全面平衡的聲音以及豐富的細節。Empire 不是主角,略過不提,我們把焦點放在Astoria 上。

使用PC Triple C 導體

Astoria 使用了Furutech 新推出的PC Triple C 導體。一般的線材多為OFC 無氧銅,而且標榜銅的純度,純度越高越好。不過,透過電子顯微鏡,可以看到無氧銅導體內部有許多不規則的結晶斷面,這樣其實不利於電子傳導。如果可以減少斷面呢?這就是OCC 單結晶銅出現的重要價值。透過OCC「大野連續鑄造法」鍛造出來銅導體,不僅有高純度,而且理論上可以達到最長150 公尺的單一結晶,因此,我們可以想像一條線可能從頭到尾都是單一結晶,沒有結晶斷面。當然,這是理想狀態,但OCC 技術確實可以有效地減少導體的結晶斷面。OCC 雖然好,但鑄造成本太高,一來因為生產速度慢,二來鑄造模具汰換率高,這些都提高了生產成本,然而線材需求卻僅止於音響市場,量不夠大,利潤不夠多。因此Furutech 想要轉彎,開發出新的製程,能夠做出比一般OFC 更好的導體,製作成本卻比先前他們所使用的PCOCC 單結晶銅更低。這就是PC Triple C的來由。那,這是什麼呢?PC Triple C 的全名是Pure Copper-Continuous Crystal Construction,也就是具有連續結晶構造的純銅導體。如果寫成「PCCCC」那實在不好看,所以原廠稱其之為PC Triple C,好讀好記。PC Triple C 採取固定角度的連續鍛造,過程中施加更大的壓力,比起一般鍛造法所施的壓力更高萬倍以上,如此一來,可讓純銅導體的結晶邊界產生一致方向,這樣一來就成為連續性的結晶體。經過這種鍛造法製作的導體,不但更有利於電流傳導,更兼有出色的柔軟度與強度,可以抽成很細的銅絲,卻不易斷裂。

結構、披覆、用料,處處講究

Astoria 所使用的線身就是Furutech 的FP-TCS21。內有三股線徑一致的導線,三股線以顏色區別火、水、地線。以80 根直徑0.18mm 的PC Triple C 銅導體絞合成一股,每一股線外使用了質地柔軟的PVC 絕緣,三股線相互絞繞,再包覆一層不含鉛的PVC,而且這層材質具有高度彈性,材質裡還摻入了石墨粉,具有傑出的阻尼特性。再向外則是一層隔離銅網,由0.12mm 的OFC 無氧銅絲編織而成,用作電磁屏蔽,最外層再有一層高彈性的無鉛PVC 作外披覆。Astoria在線材外還包上了黑色的音響級尼龍編織網,對於避震、抗靜電都有幫助。當然,Furutech Astoria 也經過了Alpha 超低溫及消磁處理,消除導體的晶體間應力,令其結構更穩定,並且也利用慢速消磁,把惱人的電磁消除。至於公母插,用上Furutech 自家的FI-11M(Cu)和FI-11(Cu),透明外殼,純紅銅接腳,導電率比起一般工業插頭的黃銅接腳更好,至於普通的鍍鎳插頭就更不用比了。這個插頭也有學問,運用了Furutech 獨家的Floating Field Damping(漂浮場阻尼,或者可稱為「漂浮磁場阻尼」)。由於電流通過導體時會無可避免地形成電場,電場則會引發微小的電流或電位差;一旦電流通過插座與插頭內的金屬零件,會伴隨產生複雜的浮動電場,這一浮動電場又會擾亂導體本身的電場,造成噪訊和失真。Furutech 在插頭內架構一個金屬橋,構成星狀接地結構,以解決浮動電場問題。是的,看起來都是電源插頭,但是Furutech的製品就是與別人不一樣。這樣一個插頭,您在市面上購買,就要一千多元,買個公母插回來就要大約2500 元,您看Furutech 是下了多少重本在這條Astoria上呢?

乾淨清晰、低頻豐潤、氣宇軒昂

Astoria 雖然只是區區8200 元的電源線,但是聲音表現確實不俗。消說原本用的是電腦用普通電源線,即便是拿其他低價入門的音響電源線,只要換上Astoria,聲音的變化立刻有感。改變在哪裡?Astoria 有著清晰乾淨的聲底,而且是全頻段的清晰。中頻、高頻乾淨清楚,就像透過乾淨的眼鏡看東西一樣,細節、紋裡都明白了,而且層次分明,有種撥雲見霧之感。低頻不僅量感要足,彈性要好,還要有低頻解析,這樣的低頻最能提供音樂豐富性。Astoria 的低頻就是這樣,它的低頻量感豐富,柔軟又飽滿的低頻,帶著些許的彈性,聽起低音提
琴真是舒服。我以為Astoria 的線徑不粗,低頻會不會不夠呢?用上才知道,這些都是先入為主的誤會。除此之外,Astoria 的音場表現也很出色,可以感覺到左右被拉開,景深也被拉開,聽來開闊有度。我用的是NuPrime DAC-10H 搭配ST-10,不管把Astoria 接在擴大機或是前端,都能收得相似的效果;整體聽感上,只要接上它,音樂就變得更精神、更昂揚、更活潑。

這哪裡是給音樂工作者的?分明是給音樂愛好者的

最後,我要再強調,這線賦予音樂更多的活力,讓音樂更顯活生。接上後,雖不至於返老還童,那樣形容實在太誇張了,卻好似在山林間散步,吸了芬多精,又來到瀑布旁,感受負離子能量,加上健走步行帶來的淋漓暢快,全人都神清氣爽起來。接上Astoria,大概就是這樣,沒有什麼讓人眼睛一亮的癖性走向,寫評論最難以言喻的「中性」,但Astoria 恰好就著了這個詞,在音色上不偏不倚,在個性上無畸輕重,道走中庸,恰如其分。果然是錄音室適用的線材,但如果您希望系統聲音不沾不染,Astoria 是個便宜又優質的選擇。
