DG-1 躍動 黑膠唱盤
評測報告:
DG-1 可算是英國 維爾特 Vertere 設計最簡單,亦是最先進的黑膠唱盤,對於欠缺黑膠唱盤設定經驗的玩家而言,DG-1 不但實踐了 ‘plug and play’ 即插即用理念,各環節亦充滿創新思維,還同時兼顧高端重播效果。技術上,DG-1 絕非單純將落實在旗艦型號身上的技術轉移過來,而是屬於由零開始的全新設計,務求在性能以至音效表現,都出現重大突破。
源自 RG-1 參考動力系統的操控線路
如果您認為黑膠唱盤動力馬達的唯一工作,就係為轉盤提供準確播放速度的話,請君三思!作為協助唱臂和唱頭把唱片坑紋轉化音頻訊號,然後傳送到擴音機的唯一動力來源,它所扮演的角色其實非常重要。DG-1 所使用的高精度24極同步動力馬達,在出廠前全數經過專責技術進行微調,旨在將噪音降至最低水平。配合技術取材自 RG-1 Reference Motor Drive 參考動力系統,內置微型電腦處理器的高精度操控線路,締造穩定流暢的播放速度。
鋁轉盤配不銹鋼主軸及碳化鎢滾珠
銀光閃爍的轉盤,嚴選原件鋁材生產,配合鋁製滑輪及矽橡膠皮帶,實現了最佳的慣性重量比,令轉速得以保持在恆定水平。轉盤表面鑲有運用 PETG 非晶型共聚酯素材生產的唱片墊,至於底部則貼上軟木、氯丁橡膠和腈素材所構成的阻尼層,有助抑制不規則諧震擴散。至於超精度主軸選用表面經過連番打磨的不銹鋼生產,配合碳化鎢滾珠所組成,達致完美的靜音運行。
三層式亞加力盤座
DG-1 所使用,內藏發光裝置的主盤及副盤環節,分別由三層不同顏色亞加力板組合而成,兩者透過矽橡膠作為耦合媒體,主盤將會提供基本操控按鈕、轉速顯示燈號與及容許用家自行取決的輔助照明燈光系統。作為容納動力馬達及相關驅動線路,同時設有三組可調校水平機腳的黑色底盤,選用鋼材製作,進一步加強穩定度。
DG-1 ‘Groove Runner’ 臂管採用三層式無諧設計
相比傳統唱臂,DG-1 所配搭的 DG-1 ‘Groove Runner’ 唱臂,最為奪目地方正是造型扁平,分別以鋁和無諧震聚合物素材生產的臂管,有效防止傳統圓形唱臂難以克服的各種共振及廻授問題。作為傳送訊號的線材,屬於高柔靭性的特製鍍金扁帶製品,從接駁唱頭的一方到RCA輸出端子,堅持採取直通車策略,減少訊號意外流失的機會。
無噪音線材唱臂軸承
力求創新的 Vertere 始創人 Touraj Moghaddam 先生認為,落實於唱臂的垂直及水平軸承,必須要輕巧和精確,工作時亦盡可能保持寧靜。務求符合這個要求,Vertere 設計團隊專誠把落實在運動範疇,透過絞合處理的尼龍線,作為 DG-1 ‘Groove Runner’ 唱臂的垂直及水平軸承。據廠方表示,線材軸承的最大好處,不但沒有傳統滾珠軸承的粘連現象或起動阻力,而且非常輕巧,工作時亦不會產生任何噪音,還擁有自我阻尼功能,只需改變線材的鬆緊度,便可控制其運動速度。
Magneto 動磁唱頭及 D-Fi 唱盤專用訊號線
所有選購 DG-1 躍動 黑膠唱盤的用家,除可享有廠方度身訂製無諧震防塵保護罩之外,亦會同時獲得實力不容忽視 Magneto 磁電 動磁唱頭,還有該社 D-Fi Analogue Tonearm Cable 唱臂線及地端引線。
