NanoFlux Speaker Cable
Top-of-the-Line Furutech NanoFlux Speaker Cable
一直不斷研發創新的日本Furutech,日前發表了最新的旗艦喇叭線NanoFlux,導體使用Furutech最頂級的α (Alpha) Nano-Au-Ag OCC單結晶銅導體。導體經過超低溫(cryogenic)與消磁(Demagnetizing)兩道程序處理。超低溫利用液態氮將導體降溫到攝氏零下196度,然後再慢慢回復至常溫。而消磁則使用專利的環形消磁處理(Ring Demagnetization)以慢速作消磁。
Nano-Au-Ag為含有金、銀超微粒子的奈米液體(直徑為8奈米, 8/1000000mm),其所含的金、銀比例是經過最佳計算與測試後決定,Furutech將此奈米液體覆蓋在α (Alpha) OCC導體上,填補了導體的空隙,有效增加了導電體面積及降低阻抗,這也是α (Alpha) Nano-Au-Ag OCC導體命名的由來。
線材結構方面,NanoFlux有正負兩股導線,每股共有7束,每束(0.18mm)為37芯Alpha Nano-Au-Ag OCC導體所組成,外面以特殊PE絕緣材質(紅/白)包覆,以棉紗填充,再包上鋁箔PET與銅網絕緣屏蔽,並採用藍紫色的特級軟質PVC 做絕緣保護,最外層為尼龍編織網。喇叭線身還配有一碳纖維避震配重金屬環,進一步強化了線材的聲音表現。
端子當然採用Furutech自家高規格產品,標準規格為擴大機端採用了CF-201(R)的Y插,喇叭端採用CF-202(R)香蕉插,其皆為Alpha純銅鍍銠導體,端子本體為Alpha無感磁不鏽鋼,最外層為碳纖維,質感一流。

喇叭線通常於系統中所有線材裡面,算是單價較高的一環,但是其可以影響聲音表現的能力算是最多也最直接,所以往往在線材選擇時,喇叭線若能夠一次晉級到一個高標準,掐指一算其實是比較划算的。之前介紹過同樣技術的NanoFlux-18電源線,曾經帶給我相當符合其身價之聆聽感受;這次Furutech再度端上如此高規技術,打造NanoFlux喇叭線。既然要頂級,就要每一處都像這條線這樣極致局,雖然不便宜,但有它引導,冤枉路從來就不在您的地圖上!

導體,已極致

再次幫大家複習一下NanoFlux重點技術面,首先,就是最基本的線身導體Alpha-OCC銅。Alpha-OCC代表其導體經Furutech開發的「Alpha Process」製成處理,這個過程包含兩項高規科技應用;一是超低溫處理,銅導體先鑄造成形後,就把它交給液態氦、液態氮,冷卻至攝氏零下196度至250度左右。這個時候,原本處於原子與原子間藉自由電子產生之金屬鍵(是讓金屬晶格固定的主要力量來源),由於溫度降低、電子動能跟著降低,金屬鍵有機會鬆動,讓晶格得以重新排列,重新排列的過程就是回溫,所以回溫也要精密的調控,必須以漸進式執行;晶格重新「整隊」的過程裡,一些殘餘應力跟著排除、原子間的「隊伍」也就更整齊了,如此銅導體之導電率就再更上層樓。第二步驟也很高成本,必須使用大型消磁機具在導體外圍緩慢移動,一些因為外在磁場干擾、形成於導體表面之局部磁力聚集,於此步驟後得以完全消除。接下來就是奈米級層面了,經上述處理過的銅導體,內部也許完美,但「外皮」可能還有不夠平滑之疑
慮,於是Furutech將自家開發之「NanoLiquid」懸浮液再用於導體上。這個Nano Liquid有三大成份:一是鯊烯(Squalene),除了提供其他成份形成懸浮狀態之外,更具去除氧化之功能;接下來就是另外兩大成份—奈米金、奈米銀顆粒,只有8nm大小,這些奈米級的元素粉末藉著鯊烯,均勻「抹平」了銅導體上可能存有的顯微凹凸不平。「集膚效應」是探討線材技術時大家熟到不行的物理現象,大家看出來了嗎?處理到這邊,這導體的表面不僅平滑了,更已經融合了銅、銀、金三種堪稱最適合拿來導電之元素。當訊號進來之後,電子傳遞根本就是如同行駛在德國「Autobahn」無限速路段上面了啊!

也太講究了!

原廠把經上段作業完畢之導體起了個專有名稱:Alpha Nano-Au-Ag OCC導體,NanoFlux Speaker Cable用上了7條線徑0.18mm的Alpha Nano-Au-AgOCC為訊號傳輸本體,外部則包覆了音響專用級別之特殊PE絕緣材質、再填充棉紗、再包覆上鋁箔、銅網作為屏蔽層、最外面才是質地柔軟的藍紫色PVC保護絕緣層、然後再加一層硬質尼龍網加倍呵護。線身中段有個電磁干擾吸收環,以獨家具高度不感磁特性的Alpha不鏽鋼打造、佐以碳纖維外殼;中間有碳纖維結合聚甲醛共聚物(Acetal Copolymer)提額外屏蔽、吸收諧振,裡面還有「含奈米級鐵結晶之陶瓷微粒」可以藉由壓電效應將外在傳入之機械振動力先轉化成電能再轉為熱能,最後通通導出。端子一
頭用香蕉插(原廠型號CF-201(R))一頭用Y插( CF-202(R)),端子本體也是用前面講的不感磁不鏽鋼、同樣有包覆碳纖維殼,端子頭則是自家Alpha純銅打磨後鍍銠,提供更佳的導電性、增加耐磨度、不易氧化。如此繁複手續,金銀銅銠合璧,技術滿滿搭載,就是只求兩個字:「完美」。

就是那高貴感

這次試聽使用的系統為Ayre CX7eMP唱盤,連接BrystonBP6+2.5B,喇叭為Odeon Nova S2。在AURORA新專輯「Through The Eyes ofA Child」一曲,前段編曲留白、營造一種靜謐時,就可以聽出浮現一堆豐富細節,包括了歌者那細小、脆弱的表情抖動,以及環境中那彷彿一根針掉到地上都可聞的小雜音,都清清楚楚。此曲最精彩的部分是三分鐘後AURORA一段無歌詞吟唱,換上這條喇叭線後,當她拉長尾音時,都還可以聽到清晰的聲帶振動;使嗓音不只是一條線,而是無數條細密之彩帶絞和在一起,投射出結構極緻繽紛的一抹光影。聽「Under TheWater」一曲,中段副歌擁有動態、音壓均強的低頻推進, 這段音樂在這條喇叭線加持之後更是不得了,快速的低頻波動就像是特寫一群野馬跑過去時那輕盈又充滿力道的馬蹄跳躍,每一下激起之塵土都是爽快;換上「百萬種硬的方式」電影原聲帶,在片尾組曲這軌,聽到了結構更為完整的管弦編制架構,特別在大量銅管鋪陳西部片特色主題旋律時,那種光芒四射的畫面感尤其
強烈;很享受那大小銅管交疊時,那結合空氣絲絲流動與金屬色澤合璧的美妙質感。在類似曲目「Main Title」中,曲子約一半時,背景中有小鼓之落點,先前聽起來頂多是有聚焦;現在更進階了,聚焦後有厚度、有明確的定位還不夠,還要能與周圍其他樂器產生交互作用,讓那小鼓的敲擊聲是可以傳遞出去的,好像每一下又乘著其他樂器一路共鳴往前,我想這就是這條喇叭線驚人之解析力還原了錄音中的魔鬼細節,也藉由那融合金銀銅三種元素之導體,呈現的美妙訊號超高完整度。各部樂器熱鬧中保持錯落有致只是基本盤,每一音色都仍是有著毫無遺漏的個別特質,這才是真功夫。

這條線換上後的聽感變化,我認為比NanoFlux-18電源線更有直接性格可以驗證,特別是多了那低頻線條中之抽絲剝繭與更加靈敏的速度推進,讓系統聲音高貴、無暇、均衡、幹練。作工與聲音真的放諸市場來看是很難挑惕了,別躊躇,想衝就衝到頂吧!

The Effective Diameter of Your Music!
The link between speakers and amplifiers is one of the most critical in a system. Speaker cables carry high current and require low resistive loss to avoid turning part of the signal energy into heat; high performance construction techniques call for large cable diameters or bundles of smaller conductors for an effective large diameter. Low resistance also keeps an amplifier’s damping factor high avoiding uncontrolled driver movements.

Furutech specifies α (Alpha) Nano-Au-Ag OCC Pure Transmission conductors terminated with beautifully-engineered high-performance rhodium-plated nonmagnetic pure copper spade connectors for the amplifier end and rhodium-plated banana connectors at the other end. The substantially-built extremely nonresonant connector bodies are finished in layered carbon fiber and stainless steel. The dielectric/insulation is audio grade special PE reducing capacitance and improving mechanical damping for greater resolution, clarity, powerful dynamics, plus an ultra-quiet soundstage in which music develops more fully without artificial upper-frequency “presence region” glare.

Furutech Alpha Nano-Au-Ag OCC is one of the best conductors Furutech engineers have found for sound reproduction.
The new technology used in the highly specialized manufacturing process of this ultra-high performance power cable combines Furutech’s world renowned Alpha- OCC conductors with Furutech’s extremely effective signal transmission enhancer, Nano Liquid, to create Nano-Au-Ag conductors. Nano Liquid’s molecules are so tiny (8 nano-meters in diameter (8/1000000mm) they cover the Alpha-OCC surface and “fill up” any concave-convex sections left on the conductor surface during the production process, increasing the electric conduction area and debasing impedance. The very precise mix of gold and silver super-micro particles and amount of dispersing Squalene oil used on the conductor has great influence on the sound reproduction, and Furutech’s engineers settled on their exact ratio of gold to silver particles after careful audition of countless test samples. The resulting “tuned” cable offers superb overall balance of qualities that Furutech is known for that allows you to feel experience and communicate with music. The results are extremely fine resolution down and through the very low noise floor, improved sound staging and image palpability, a musical, attractive, “round” midrange, tight and controlled bass, plus power and dynamics to spare to set your music on fire!

In short, everything in the signal path does indeed make a difference. Hear and see the difference that the Nanoflux speaker cable can make in your system.
