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。{:6_176:}
樓主, 有冇 "肉照" 睇睇 ? Thanks! {:6_142:}

Thirty years ago, the upstart audio company NAD revolutionized the manufacturing of consumer-electronics components by "internationalizing" the process. Instead of physically making products, NAD hired a project team in one location to design a product that was then built at a sub-contracted factory located elsewhere. The arrangement allowed NAD to go into business with relatively little capital outlay and low overhead. Other companies have since copied this ingenious business model, and, as transportation and communication have improved, doing so has become easier and more efficient. It has brought prices down and quality up—mostly in the low and middle segments of the high-end audio and video markets.
I haven't studied San Francisco-based Parasound Products' business or its books, but the NAD model has clearly been an influence on Parasound, which was founded in 1982. The Parasound Halo JC 1—a powerful, sophisticated premium product—was designed by a team headed by audio legend John Curl, and built for Parasound by a factory in Taiwan. It takes the outsourcing concept way upscale while keeping the amplifier's price down to a remarkable $3000 each. The 5-to-1 ratio of cost to retail price that is the norm in the audio industry suggests that the "raw" cost of the JC 1 is about $600—a number almost impossible to believe, given the superb build quality and sheer heft of this powerhouse monoblock.
