Analog Quality Compact Disc (紫銀合金AQCD) 是一種全新的製碟方式,採用特別研發的紫色基片,以更耐熱、耐光的銀合金取代傳統的鋁質反射塗層,透過日本Memory-Tech技術印製,減少了數字CD光碟的誤差,提高了音頻重播的精確度,無論現場感,平衡度與細節表現都有了很大的改進,音效表現明顯比一般CD優勝,高音質的紫銀合金AQCD,重現黑膠唱片的超凡魅力。  
 
CD的流行已經超過了四份之一個世紀,這種嶄新的數碼音樂軟件帶給了人們很多歡愉和享受。和黑膠唱片相比,CD方便、耐保存,但是在音質方面,CD尚有改善空間。近十多年來,出現了各式各樣的制式和規格,以求改善一般CD的音質。一片小小的CD製作,其實內裹包含非常精妙的科技。從錄音、編輯、刻製母盤到壓碟,是一個非常複雜的過程,任何一個環節的微小錯漏和瑕疵,都會影響到最後成品的質素。經過多年的實驗和研發,AQCD研發團隊終於開發了AQCD技術。  
 
AQCD使用了紫色基片,經科學鑑定,紫色使到紅色激光光束更為聚焦,拾取之音訊便更為精準;而最新研發出來的銀合金反射塗層擁有更高密度特性,其反射力特強,光譜改變更少,從而使AQCD的時基誤差(JITTER)被減低四份之一。  
 
其次,CD碟是圓型物體,最理想是做到“絕對圓心”,然而,零偏差是不可能的。一般CD的ECC(偏心)製造標準是0.07mm,這個差距是非常少的。但由於鐳射光速的直徑只有0.0001mm,所以偏心越大,擺動也越大,雖有伺服器的幫助,但在高速轉動之下,錯漏也無可避免。AQCD的ECC(偏心)側只有0.04mm,比一般認可標准提高了42%,這個精確度可以使激光光束拾訊時更為準確,誤碼率大大的降低,失真率也更小了。  
 
最後,負責監督AQCD壓碟的是日本MEMORY-TECH,旗下工廠生產線的成品平滑度和平均厚度是近乎完美,保證了AQCD的品質。  
 
綜括,AQCD技術從制作母盤、機械壓碟、到碟片的材質處理,在每個環節上的技術和質量控制更加精確,經AQCD技術處理再還原出來的信號波形與原始的模擬信號波形更為接近,從而使音質更加純淨逼真,整體表現出更為理想的效果,聲音便更富有模擬味道。

新浪娱乐讯 CD的流行已经超过了四份之一个世纪,这种崭新的数码音乐软件带给了人们很多欢愉和享受。和黑胶唱片相比CD方便、耐保存,但是在音质方面,CD前面仍有一大段路要走。近十多年来,各大唱片公司都竞相开发新的技术和规格,以求改善一般CD的音质。在开发新的CD规格的时候,都是以16BIT/44.1KHZ CD标准为基础,他们都围绕着以下三个要素来作考虑:首要当然是音质,其次是新制式的相容性,最后是市场上价格的竞争性。环顾当前不同的新CD规格,有些以音质取胜,有些是相容性广,而另外一些则是有较高的性价比,真的是百花齐放,各擅胜场。  
 
  近日,由广东音像城发烧天碟俱乐部AQCD研发中心及上海联合光盘有限公司公司memory-tech(Shanghai)共同研制出来的AQCD技术,从刻制母盘、机械压碟到碟片的材质处理,在每个环节上的技术和质量控制更加精确,经AQCD技术处理再还原出来的信号波形与原始的模拟信号波形更为接近,从而使音质更加纯净逼真。通过AQCD技术制作出来的CD碟片,只用普通的CD机播放就能够听出明显的音质改善,声音效果非常细腻,更加接近原始的母带。  
 
  广州著名HIFI歌手陈洁丽向周璇致敬的“浓情”专辑率先采用AQCD技术,以其出色的录音和演绎水准获得国际华语音乐联盟主办的华语金曲奖2009十大华语唱片HIFI冠军,而研发方除与星外星、新京文等公司合作,推出“红楼梦”、“龙鼓”、“苏曼的夜晚”和“民歌红”等专辑外,还相继与EMI百代、香港现代唱片、风行唱片、发记唱片、台湾鉴赏音乐、海山唱片等经典厂牌合作,推出上世纪30年代的上海国语时代曲精选以及蔡琴、费玉清、甄妮等巨星的早期代表作,以无可比拟的音质重现那不朽岁月的天籁之声。  
 
  广东音像城发烧天碟俱乐部AQCD研发中心将与以推动华语音乐在全球普及发展为已任的国际华语音乐联盟携手,以新技术为核心,为低迷的华语唱片业再次注入新的动力!

Morning gents,  
 
After couple years of hard work and steadfast effort, Leo finally gave birth to his latest venture "AQCD" (Analog Quality Compact Disc) launched in stores all across. With copyrights and political BS rooted in the business, been a frustrating journey for Leo to say least. Had a chat with him before the launch on this new format and likely will organize a PR1 workshop to have some fun with it once we get our shit together. In the mean time, a little background info on this 紫銀合金AQCD技術 .  
 
Again Leo, my heartiest congratulation!

Neutrino88, please sit down while you're reading this.  
 
With a stack of cash in my pocket, I went by the Sony store yesterday ready to load up on the Sony DVP-PR50P and was told it does not exist anymore!!! They were removed from the shelves 2 months ago. The news came as a shock since it was a big seller and one of very few players on the market that plays "everything". I was devastated. The hunt is on!

Neutrino88 , not fair! The Sony DVP-PR50P (aka the Poor man's Studer) is an unbeatable deal. I use it almost every night watching movies and unlike my 4 other DVD players costing 10 times more, it plays "everything" and does it well!! At the price of $380 HKD which I paid at a Sony store, the best return on my investment in recent years. Rumor has it that other shops in HK were selling them as low as $260 each!  
 
ps: Btw, Sony also has a pretty hot new SACD/Cd player out causing a stir in the hi-end market, will post more info at the "Basement Project" thread.

Not yet Neutrino88, spent a little time with it at the showroom. The overall sonic picture seems balance. It plays RR recordings exceptionally well ( think it has to do with the Sony head), but I'm not sold on the idea of " tuning" at freewill by the user. Not yet anyway. Are you thinking of buying one?

Morning gents,  
 
 
Got a call from Leo last week inviting us to sample his newly designed CD Player, a joint project with his bud Mark of Hit Audio. Apart from the name "Marklos" (Mark + Leo , get it? ), other strange qualities of this CD player is that it employs two 6N9P valves and uses a Sony laser head 213Q. An intriguing combo not just because it uses 6N9P tubes but the Sony 213 laser head is a deadly, underrated giant killer! Remember years ago when the ridiculously affordable Rotel RCD-951 and 971 took the market by storm and had the big boys running for covers? In fact, both CD players stayed for the longest time on Stereophile Recommended list (3-4 years I think?), and in 1999, the 951 was the cheapest CD player ever took a Golden Ear Award in TAS (issue #121). Yes, you guessed it, they all uses the Sony 213C! In any case, a new demo unit be made available to us and most likely will make it's round to the homes of our panel.

Dear Kris :  
Please help pass message to Leo that Ruby was unable to get through  
to the phone number he left in my post box. This could be due to lapse  
of time or maybe Leo is not in China now?  
Please help ask what's best time to call him at the phone number  
given. Thanks again for all your help.
