前言:
眾所皆知,我換了Wilson Benesch Vector 已經有一段一子,亦差不多將之煲透煲熟,開始要想想如何升級了。現時的Rogue Audio 合併機夾出來的聲音我是滿意的,之不過在購買Vector時在「凌智」試那套Ngara Classic 前後級實在太過震撼,配合Vector 的聲音實在叫人難忘;話雖如此,Nagra 的價格實在不非,之前換喇叭已經洗了一大筆,都要作重新預算。要發揮遇強越強的Vector, 絕對不能「虧待」佢,個人屬意以一套前後級好好招呼佢,而價格以十萬元內為基準,希望可以介紹一些前後級組合比大家同自己參考,先來第一個單元.....
Rogue Audio RP-7, Rogue Audio Stereo 100
第一個單元寫Rogue Audio, 原因只得一個,就係熟!
當然自己都係Rogue 用家,其特性也略知一二,記得第一接觸 RP-7 是在Racewong 家裏,當時他仍是屏風用家,以RP-7 取代某美國品牌,論動態及霸氣,仍然是A 牌略略佔優,但以聲音通透度,中頻水份來說,RP-7 實在可以完勝,屏風加Bryston 後級聲音偏硬,RP-7 有著全頻潤飾的作用,亦是我多次作客鎗王家最好聲的一次;不過當時自己玩Tannoy 及 Mangnum II 也相安無事,所以未有太大的換機衝動。
當然往後的事大家都知,WB Vector 正式入宮,而故事就如上文所說 ..... 要嚴選、當然要做下功課,RP-7 是一部膽前級,用上四支12AU7 膽,三組RCA 輸入,兩組全平衡輸入,另外有AV Bypass , Processor Loop, fixed 及 variable 輸入端等等;前面板仲有headphone 輸入及mono 制。
Stereo 100 為雙聲道膽後級,用上一對12AU7, 一對12AX7, 四支KT120 功率管,有三極及超線性輸出,三極輸出有60瓦,而超線性可達100瓦;4ohm 與8ohm 喇叭有專屬binding post, 有RCA 或平衡輸入。
Part 2 試音,依然是在Racewong 家中,RP-7 仍在,但係喇叭以由屏風轉為Genesis Maestro,Maestro 為半有源喇叭,每邊五隻單元需要用Amp 推,對於我用緊的二路半三單元的Vector 應該有一定指標性。先試三極輸出,人聲真係好靚,靚到直情有聽EL 34, EL 84 那些細瓦膽機的感覺,不過有同樣問題,控制力有點不足,立刻轉到超線性,聲音立即更為平衡,高低伸延更加理想,控制能力不俗,過往RP-7 所營造的通透感仍在,KT120 作功率管並不粗聲;以我玩Rogue Audio 的經驗,此牌子對膽要求不高,一般二三佰蚊的Jan 膽已經可以玩到靚聲,而在場這部Stereo 100 功率管更只是原裝的Tung Sol KT120, 對於玩家來說是一大喜訊。
Part 3, 上星期無聊又上膽王吹下水,Mark 哥話部RP-7 換了新膽,是美國Bendix 5814WA,問問多少錢?原來$1200 一支,夾返Stereo 100, 推Graham , 除了聲音通透之外,仲有浸浸貴氣,Rogue Audio 夾貴膽又真係可以去到另一個境界,以這組合夾英國喇叭都相當不俗!
總結:
RP-7 $41000 , Stereo 100 $29800,價錢只係七萬,以十萬預算還有空間買線,加上可以換膽,可玩性甚高,雖然是美國機,但聲音一點也不粗,換一些平價放大膽也有相當好效果,力量和控制力不用懷疑,一般座地喇叭也應付自如,平衡及非平衡輸入端子十分足夠,對於雜食玩家一定歡喜,若不是「恐膽」成症的話,這個組合是一個不俗的選擇。
