同舊版有乜分別?

肉眼睇到:
1. 個嘜頭。
2. 面版和機背鐵手柄。
3. 機背標明Power Consumption 1800w,與A51一樣,但Spec又話2500w;舊款標明2500w,是否暗示两隻環牛????
4. 機背五粒聲道volume調較制,Auto on/off和Ground Lift。
舊款街價都係賣成HK$19~20K喎,雖然佢話二萬係人仔,折合港幣就要成HK$24K,打個八八折就成HK$21K,Halo Series唔轉款加大價,5250改改加仟零二仟哩。

輸出和體重都一樣。利用訊号Auto on/off功能簡化咗,Ground Lift改善Ground Loop Hum又無咗,五聲道音量獨立調節,即係五只香爐,就是這樣都足夠有60點改動,不過,無仲好呀,Parasound。 |
