Apex Stereo / Mono 頂峰 純A類立體聲 / 單聲道後級
評測報告:
號令天下 莫敢不從!
丹麥 貴豐 Gryphon Audio Apex 頂峰 後級的出現,難免令發燒友重新改寫 "重量級" 一詞的定義,即使是提供 2 x 210W 輸出的 Apex Stereo 立體聲版本,淨重已經超過 200kg,如果是 225W 輸出的 Apex Mono 單聲道版本,重量便是倍增!出自創辦人 Flemming E. Rasmussen 先生手筆,龐大但精巧的面板造型,主要包含2件厚重的長方形及1件散熱器造型鋁合金板件,襯托三角造型,提供操作資訊的顯示屏幕,塑造出與眾不同的優雅氣質。位於機身兩旁,設有8組預先經過打磨及黑色陽極處理的高效率散熱器造型,至於同樣貫徹約束層阻尼 Constrained Layer Damping 三文治避震理念的底盤,以不同質量非磁性物料所構成,免除機內敏感零件受到干擾的機會。接駁上,Apex 頂峰 後級只提供 XLR 平衡輸入,而 Apex Mono 則增設 XLR 串連輸出,至於可容納香蕉型,Y型及裸線的大型喇叭線接駁插座,亦屬廠方自行研發的專用製品。
每台使用64枚功率管
Apex 頂峰 貴為 Gryphon Audio 新一代無所不用其極的超級功率發電機,選料製作當然絕不吝嗇,當中包括落實於訊號傳送及電源環節的接駁線材,全屬自家生產的純銀製品。線路環節仍然堅持採用工作效率偏低,但聲音質素有所保證的零迴授全平衡直流伺服耦合放大線路,雙差動輸入緩衝級以超低電容量 J-FET 組成,極為壯觀的強放環節分別用上了32枚 + 32枚 (Apex Stereo) 及 64枚 (Apex Mono) 經過嚴格配對,具備大電流輸出特質的雙極晶體管,數量較現時 Mephisto Stereo 及 Mephisto Solo 所用者大幅增加60%,唯獨輸出功率處於 8Ω 負載下,只錄得頗為保守 2 x 210W (Apex Stereo) 及 225W (Apex Mono),但當下跌至 1Ω 水平時,功率數字將會瞬間飇升至 2 x 1,490W (Apex Stereo) 及 1,690W (Apex Mono),意味著 Apex 頂峰 必定具備前所未有,無堅不摧的龐大電流輸出。透過微電腦進行監察,可作自動或高、中、低三段手動設置的綠色偏壓設施 Green Bias,令 Apex 頂峰 處於任何狀態下,仍能保持在純A類工作模式。
1百萬微法拉能量儲備
要應付大量雙極晶體管強大的能量需索,幕後必需設置一套沒有樽頸和上限的供電系統,方能水到渠成。每台 Apex 頂峰 將會使用2枚 2,000VA 特別訂製環型變壓器,還各自配備金屬製屏蔽罩及懸浮避震裝置,免除充電時所產生的微弱諧震漫延到機內其它零件,從而引發干擾的機會。8支總容量高達1微法拉 (1,040,000uF) 的電解大水塘,透過表面經過拋光及鍍金加工的銅條進行連接,加上德國 Mundorf 出品,損耗系數較傳統金屬化聚丙烯薄膜電容低10倍之 MCap® ZN Classic 發燒級薄膜電容作為供電退耦,有助進一步降低電源阻抗。順帶一提,即使是 Apex Mono,每台亦必需使用2條IEC C-16規格的電源線,才能順利啟動。
