中音路- 離子高音 Plasma Tweeter of 2.1 channel ...the END!

Finish!

羅老 sorry 轉貼 Look-T blog...
點火....一道紫色光噴出，送上音樂一陣奇妙的聲音在耳邊響起，調好音壓比例，哇.....小提琴的嚓弦聲絲絲入扣，整個音場空氣感十足，這才算是超高音，以我的經驗所有有型體的喇叭發出的氣聲，音質和擴散性真實感都跟不上離子高音，真實感尤其重要，我們多數的音響都只能說好聽，認真說來就缺這種如臨現場的真實感！

另羅老全新架構300B SE

羅老........十年對管機和輸出變壓器的浸盈研究 ...... 的感性論述.
這新架構的機器背景特別乾淨，一開始有點尖銳，開機一兩小時就相當好聽，現在5分鐘我就感覺到位了，所有的樂器像是跳出來似的，非常的透明立體，單端管機的霧霧感都沒了，再說這樣的霧霧感覺可是花了10年才解決，這也是這機器最大特色。

敝人覺得.....對管機有鐘愛的同好, 一輩子對聲音尋尋覓覓的朋友, 別忘了這個...有可能一解您的宿願.
