我同樓上位ching1樣，所以昨天買了部二手5007,之前係905，發覺D聲細緻咗好多。
當然大升up

路過搭問: 我都想升...608 >> 4810
我上網睇到好似5007 AND 5008 都係用1795 X 6粒~~~
而DSP 就大家都係3粒,不過我見5008 用DA830 X 1, DA877...

揭秘日系AV功放的檔次劃分與分級&選擇
轉載至http://www.av199.com/thread-309018-1-1.html
隨著數碼技術的發展，現在次世代AV功放是一年一代，JS在圈錢的同時也給玩家帶來了痛苦的快樂。現在地球上能被普羅大眾能接受的次世代AV功放基本上是日系的天下，可供選擇的基本上都是小鬼子五大家族的產品
五大日系的AV功放每家的產品線都有明確的檔次分級，分別是：入門級、中級、高級和旗艦級。這四個級別是如何劃分的？我們根據自己的喜好和需求又如何進行選擇呢？下面談點個人意見，歡迎各位DX拍磚。
日系的AV功放的檔次分級的主要依據是：DSP、DAC及輸出功率。根據這三個要素的不同搭配來確定檔次，基本規律是按DSP < DAC < 輸出功率來進行組合，比如DSP和DAC的芯片相同，輸出功率大的型號比輸出功率小的型號高一個級別，而DAC用的是一片8CH還是多片2CH決定了機器的檔次。

Onkyo TX-NR5007 AV Receiver Review Quote:
"In the mean time, the TX-NR5007 is a technical tour de force that hit's all of the currently required marks asked in it's price class and sounds great across the board. It's value for money will largely depend on how many of the features, for which you are paying, will actually be of use, but the big Onkyo is deservedly going to find itself finding a place in many homes on the basis of it's audio performance alone."
Pros
High Power
Flexibility
Movie Performance
Rewarding with Music Playback
Smooth
Unfatiguing
Every current feature under the sun
Cons
Unit size and depth, measure your AV Rack
Almost too Complex
Movie excitement doesn't quite translate to music
Runs warm, not for enclosed cabinets

FULL HD AV AMPLIFIER Verdict:
"The Onkyo TX-NR5007 holds its own in the rarefied atmosphere of top-end receivers and does so at a distinctly down to earth price. It has every feature you could need for a comprehensive AV hub, is hugely entertaining with movies and offers a smooth and sophisticated if not highly detailed presentation with both stereo and multichannel music. It's fully featured, eminently enjoyable and near half the price of its rivals - what's not to like?"
Award: HIGHLY COMMENDED

揭秘日系AV功放的檔次劃分與分級&選擇
轉載至http://www.av199.com/thread-309018-1-1.html
天龍4810--DSP：SHARC處理器×3，DAC：PCM1791×6，輸出功率：180W×9（19.1KG）
AVC-A1HD是天龍合併機旗艦，6片PCM1796提供12聲道處理能力，雖然機內只設置7聲道放大器，但是機後提供了9.3前級輸出接口。 A1HD與4810的DSP採用的是3片32BIT的SHARC處理器ADSP21367，該處理器的主頻為400MHz，因而A1HD與4810具有非常強悍的前級性能。 非常期待天龍的3D功放4811。
從上述數據可見天龍的4系列明顯比123系列高了一個檔次，而123系列級別差異主要是輸出功率的大小的，如果喜歡天龍最好選擇4系列。 如果喜歡玩前級+後級，一個高性價比的玩法是用1911做前級然後加7CH後級。 但是小鬼子的就是精鬼，它的1911就沒有PRE OUT！ 要做前級就得加米買3311。 日本本土銷售的2311是有PRE OUT的，據說國行的2311不帶PRE OUT。 這個現像在其它的鬼子機器中也存在閹割PRE OUT口的情況。 受消費水平所限，用低級別AV功放做前級+後級（DIY、二手）是中國特色，小鬼子深知這點。
其實加PRE OUT口非常簡單，對於有動手能力的DIYER玩家完全可以買個1911加PRE OUT當AV前級，堅決不讓小鬼子的陰謀得逞。 雖然1611是5.1功放，但實際上它前級部分與1911一樣內部核心是7.1的，只不過功放部分是5.1的罷了，所以用1611改前級更合適，性價比更高。
儘管天龍新出的3311以下等型號功放均支持Dolby Pro Logic IIz的前方增高模式，但是由於DAC只支持8通道，故不論採用什麼模式都只能輸出7.1聲道，要開Dolby Pro Logic IIz的話只能關閉後環繞，即使想另加一台雙聲道功放也不行！
天龍4311是最新出的型號，但這個型號令人大所失望。 雖然用到了2片DSP芯片，且內建了9個放大器，支持9.1聲道，但DAC用的是2片8聲道DAC芯片AK4368。 主要性能指標：信噪比112dB，動態範圍112dB，總諧波失真-94dB，這樣的性能指標還不如PCM1690！
今年真奇怪，天龍、先鋒都在中高檔機中採用AKM公司的DAC芯片，但至少先鋒還比較厚道點，用的是四片AK4480（信噪比114dB，動態範圍114dB，總諧波失真-100 dB）。
好詳盡{:1_351:}
ching:808到5007音質,分析力,力水三方面，都會提升{:6_193:}
