熱門新玩具 DAC 解碼 (入門篇)

現時很多想升級CD盤的玩家, 用DVD機聽歌的玩家, 很多時預算和地方有限, 都會改為
加上一部DAC (Digital to Analog Converter) 來升級音源。

很多廠為了控制成本, 制作CD盤內解碼部份, 採用一些平價多功能解碼晶片,
部份更內置HDCD解碼, 支援24Bit 192KHz
"支援" , 非真正 Up Sampling to 192KHz, 真正內置升頻的CD盤很少。
加上用料的質素, 電源穩壓, 電容等

DVD機方面, 24Bit 192KHz 已經是基本要求, 為何會輸給一部24Bit 96KHz, 甚至16Bit
DAC?
因DVD盤的解碼是多聲道, 主要是睇戲, 跟2聲道聽歌的晶片是有一段距離。

所以已經是24Bit 192KHz的CDP/DVDP, 再加上一台24Bit 96KHz 的DAC, 都有進展

另一個DAC的故事, 某L廠制作一台CDP, 以AD1853作D/A解碼
另制作一台以AD1853作D/A的外置DAC, 2者線路相似, 用料一樣, 電源穩壓一樣
但外置DAC加在CDP上, 明顯比CDP內置解碼的背景寧靜和幼細, 這是分體的好處
就像合併機和前後級的分別

dynamicdog, thanks for the information, I would like to know the basics of upsampling. Why up sampling is required if the CD was mastered without so much details?

咁如果Speaker & AVM不變又想upgrade音源,
Option-1: 加隻DAC好D?
Option-2: 定買多隻pure CD Player好D呢???

一般CD 本身是16Bit , 如果將她Up Sampling to 96KHz... 192KHz, 聲音會更細緻, 細節會聽得更多, 音場更闊

如果打算加 DAC 或 把DVDP upgrade to pure CDP
要睇預算, 如果以under $3000買CDP, 不如加國產under $1500 DAC 更有驚喜
再上Over $5000, Benchmark DAC1, AQVOX D/A 等歐洲機會有更高層次享受
而且是真正Up Sampling to 192KHz
Pure CDP 平價歐洲機不是好選擇, 貴價國產機更不值價

"國產under $1500 DAC 更有驚喜" !!??
有無好介紹先等小弟去研究吓, 我本身用開Onkyo D入門AVM (~$3xxx), 80%聽歌, 20% see DVD 我都想整靚D聲聽歌. Many Thanks!

Goldlightan兄:
我都用ONKYO 702 AVAMP加SONY DVDP, 聽歌在AVAMP中算好, 但分析力就非常底
你可以試下 麗特LITE DAC-AH, 價錢平, 7百多元, 一套AV器材, 加上DAC, 改善好大
此機厚聲, 音樂感好, 聲耐聽

dynamicdog兄,
HK$ 7xx又幾低玩wo, 睇相是否好似手掌咁大?? 那裹有得賣呀??

Connection 是否 DVDP --> Coaxial --> DAC --> Coaxial --> AVM ??
睇DVD有影響嗎??

Goldlightan兄:
比手掌大DD
如果要平, 可以上網bit $780, 觀塘有間音響鋪好似都係賣$780
出面要$850 - 1000左右

聽歌 DVD ---> Coaxial ----> DAC ----> Analog ----> AVAMP

睇戲 DVD ---> Coaxial/Optical ----> AVAMP

如果你想睇DVD都用 Coaxial, 咁要一開二, 聲當然有影響

dynamicdog兄,

同你差不多我用緊Onkyo 603AVM, Onkyo 502 DVD Player 經Coaxial去  B&W speaker 來聽歌及睇戲.

現在的 connection 係,
聽歌: DVDP --> Coaxial --> AVM
睇戲 Audio: DVDP --> Coaxial --> AVM
睇戲 Video DVDP --> 色差 --> LCDTV (靚過经AVM)

麗特LITE DAC-AH可同時接 Coaxial Out (聽歌) 及 Optical Out (睇戲)去AVM嗎?? 要用靚的RCA cable嗎??

觀塘那間音響鋪有待賣?? 我去過旺角友誠 & 德發都無.
Many Thanks!!!

Goldlightan兄:
以你現在情況, 聽歌改用RCA去AVM會比Coaxial好
如果加DAC, Coaxial入DAC, RCA出, 去AV AMP
Optical去AVAMP睇戲, 效果無Coaxial 咁好, 你可以, 1. 改機, 2. 一開二分插

觀塘Hi Fi 鋪, DAC款多, 有幫人改機, 有麗特產品, 比旺角、鴨記平

德發, DIYCLUB 係麗特香港總代理, 產品齊全, 有套件, 有成品, 主要做出口生意

Thanks dynamicdog兄,

請問用多少$$$嘅RCA cable先配合到DAC的效果??
DAC除令分析力好咗之外, 可以出到温暖圓潤 (少少似胆机) 的效果嗎??

若 DVDP --> Coaxial --> DAC --> RCA (Analog) --> AVM 仲睇到DTS碟嗎 (input 是 analog)??

[quote:c0b52c0acb="Goldlightan"]Thanks dynamicdog兄,

this connection can not decode dts, you should connect via digital connection, (coaxial / optical)

But you can connect the rca to your AVm's CD input, and connect the digital cable to your dvd input.

dynamicdog兄,

有冇聽過Diyeden?

你們好

我用緊部marantz cd 7300 cd player,  現在想upgrade,  應該加過 DAC 解碼 around $10000,   還是買過部 AROUND $1XXXX 的 cd PLAYER (e.g Linn, Arcam)
請指教邊個方案好??或另一個第三方案尼

簡單D講, 聽歌經DAC, 睇戲唔經DAC, Digital 直入AVAMP

線材方面,
國產無牌子或雜廠線, 聽聲收貨, 無得試聽, 無得比較, 唔買!
國產大廠, 秋x原等, 買左可能會後悔
歐美線方面, 多數價錢同音質成正比, 有錢無所謂, under $1K 唔好有期望

DAC方面, 要暖聲厚聲有膽味, DAC-AH算比較接近, 因解碼chips用PHILIPS TDA1543, 8粒

其他牌子...DIYEDEN, 分析力和動態比DAC-AH好, 但AD1852聲不夠厚、暖,跟DAC-AH相反

各有千秋

mr.fish兄:
如果你要知邊樣好, 方法只有一個, 帶埋自己部CDP去其他鋪頭做AB比較
DAC又好, CDP又好, 玩音響,唔怕煩,只怕買錯

under $10K DAC, Benchmark and AQVOX is good

多謝你的回覆,
請問 Benchmark & AQVOX 邊度有得睇, 試
有無XLR 輸出, 邊部好
如用Linn CDP $1xxxx,   應用???錢 DAC 才成正ｔ匕

Thank you so much!!!!! DAC-Ah is most suitable for me, thx

In your case,
Coaxial Must better than analog RCA interconnect, base on which part decoding.

For stereo audio part.
If you have a 10K CDP >> 7K AVAMP,
use 10K decode may be better than 7K AV amp decode, then use interconnect.
If your 4K DVDP >> 7K AVamp, Must use Coaxial out to your AV AMP to deocde, use digital transfer better than analog transfer.
Both choice better use same grade of cable.

Coaxial part of DVDP, seldom go to 改機, 2. 一開二分插,
No one know the result and quality.
DVDP now is not expensive, Why not buy another cheap DVDP or better Pure CDP, seperate to do the music and Movie part, the price of 改機, you may get a new Philips12 bit dac DVDP below $1000.

Goldlightan

Explain clearly, your case is DVDP to AV AMP, not Pure CDP, totaly different sound effect because of the budget for Video part or audio part.
DVDp not main focus on sound but main focus on video chips, Pure CDP, Must focus on audio only.

If you use 4k CDP may be better than AV amp decode but use interconnect will have lost you may consider, 4K DVDP's sound, different from 4K pure CDP,

finally coaxial or interconnect/ digital or analog which one is better, trust your ear. happy listening

用一開二分插, 質素一定會差少少

幾百蚊讀碟王DVD機, 個個都俾得起錢, 只要你有地方放
器材一部一部疊上去, 質素更差

Benchmark and AQVOX
都有AES/EBU , XLR , Coax , Toslink) inputs
Benchmark 個 Coax is BNC type, not RCA, (BNC is better than RCA, real 75 Ohm)
AQVOX 有得玩Oversampling : 32Fs, 64Fs, 128Fs 同埋Digital Filter

DDL Thanks!!
I am become understanding the design between DVDP decode and AVM decode now. For music improvement, seems I need to consider seperate player for CD & DVD. 講開又講你條Reference同軸真係越煲越有力, 音牆濶咗, Bass都好咗. Thanks!

係呀dynamicdog兄,
喺香港地方真係好大問題, anyway thank you very much for your teaching.
