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
