calvin1800 寫: Why Denon AVR-1611 and AVR3311, DAC is same as DSD1608x 1??? :angry2:


:a005: :a005: :a005:

DSD1608 --> 108dB SNR 8-Channel Audio DAC

:announce: :announce: :announce:

7.1 Channel (8 Channel) 八聲道

高級机一般用 Stereo (兩聲道) 高級 DAC (>120dB SNR) x 4

中級机一般用 Stereo (兩聲道) 中級 DAC (~110dB SNR) x 4

入門机一般用 8 Channel (八聲道) 基本級 DAC (~100dB SNR) x 1

:announce: :announce: :announce:

其實 DAC 本身的價值差別並不很大,也並不昂貴 (HK$12~HK$83/粒)

Unit Price per Lot Size of 1,000
1792A -------------- US$10.65
1794A -------------- US$10.65
1795 ---------------- US$3.95
1796 ---------------- US$2.95
1791 ---------------- US$2.25
1680 ---------------- US$1.50

:049: :049: :049:

音響器材廠商要設計及做出適合 DAC 的精密及高訊噪比電路

用以發揮它們各自的性能,才是關鍵和價格差別的來源

設計及用其他線路及零件配合 4 粒 Stereo DAC 輸出八聲道

必定較只用 1 粒 8 Channel DAC 輸出八聲道更複雜及昂貴

:003: :003: :003:

故高級机用多顆高性能的 DAC 作音頻處理及精確高訊噪比解碼是匹配的

:a009: :a009: :a009:

Pioneer SC-LX90: WM8741 (128dB SNR) × 6 --> 1 DAC for 2 Channel

Pioneer BDP-LX91: WM8740 (120dB SNR) x 8 --> 1 DAC for 1 Channel

Both WM8741 and WM8740 are classified as high performance top-of-the-range DAC within Wolfson.

cocacola99 寫: How about lexicon?


:003: :003: :003:

Lexicon MC-12 uses Dual Mono DAC (24 Bit / 192kHz) for Each Channel

MC-12 是 7.3 Channel 輸出 --> 即共 10 個 Channel

每 Channel 用一粒 Stereo DAC,即最少用上 10 粒 DAC

:guitar: :guitar: :guitar:

但唔知用乜品牌及型號

待我去 Official Forum 打聽下

:question2: :question2: :question2:


:003: :003: :003:

Lexicon 的 Todd Packer 回覆了

Lexicon 舊的 MC-12 與最新的 MC-12HD,均用同一粒 DAC

Analog Devices AD1853 (117dB SNR 24 Bit / 192kHz) Stereo DAC

用了 10 粒 Stereo DAC,每粒供 1 個 Channel (Dual Mono Mode)

:guitar: :guitar: :guitar:

Lexicon 也同用了 8 粒 Analog Devices ADSP-21065L SHARC® DSP Engine

及 Cirrus Logic Crystal 49326 Audio DSP

一般日系主流高級机種用 3 粒 SHARC® DSP Engine

:love_china: :love_china: :love_china:

Lexicon MC-12 是 2003年推出,當年已用 10 粒 24Bit / 192kHz DAC

經過多年 Upgrade

MC-12 V2 (軟件升級)
MC-12 V3 (軟件升級)
MC-12 V4 EQ (加 EQ Card 硬件升級)
MC-12 V5 EQ (軟件升級)
MC-12 V5.25 EQ (軟件升級)

MC-12HD V1 (加 HDMI 硬件升級)
MC-12HD V2 (軟件升級)

MC-12 V1 --> MC-12HD V2 音頻解碼部份,仍無改變

:hypno: :hypno: :hypno:

我的 MC-12B V5 EQ 也只作軟件升級至 MC-12B V5.25 EQ

因用 Analog 輸入,MC-12HD 新加的 HDMI 對我無乜用

故無由 MC-12B V5.25 EQ 升級至 MC-12HD

待下次 Lexicon 再推全新架構的机種取代 MC-12HD 才作考慮

:049: :049: :049:

Pioneer BDP-09FD --> 5.1 Analog --> Lexicon MC-12B V5.25 EQ 效果仍是不錯

:049: :049: :049:

I do not know.

However, according to Todd, they are now developing a new machine to replace the MC-12HD.

But they also express that the HDMI is moving too fast for them to cope with.

:confused: :confused: :confused:

Let's wait & see.

:question2: :question2: :question2:

This is why I am interested in knowing anyone within AV100Fun that using the latest Mark Levinson No.502 Media Console which is similar to or slightly more advanced than MC-12HD V2.

I really like to listen and audit its performance.
