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作者: goofy 時間: 2006-2-3 19:52
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?作者: goldlighta 時間: 2006-2-4 00:54
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???作者: dynamicdog 時間: 2006-2-4 20:41
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作者: goldlighta 時間: 2006-2-5 23:37

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?作者: fish 時間: 2006-2-10 19:07
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作者: dynamicdog 時間: 2006-2-10 21:24
簡單D講, 聽歌經DAC, 睇戲唔經DAC, Digital 直入AVAMP
under $10K DAC, Benchmark and AQVOX is good作者: fish 時間: 2006-2-10 23:05
[quote:7c3074e05b="dynamicdog"]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[/quote]
Thank you so much!!!!! DAC-Ah is most suitable for me, thx作者: goldlighta 時間: 2006-2-11 01:38
[quote:cdb44e52bf="Timate"][quote:cdb44e52bf="Goldlightan"]Thanks dynamicdog兄,
若 DVDP --> Coaxial --> DAC --> RCA (Analog) --> AVM 仲睇到DTS碟嗎 (input 是 analog)??[/quote]

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.作者: ddesignlab 時間: 2006-2-11 05:58

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作者: dynamicdog 時間: 2006-2-11 15:56
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, 質素更差作者: dynamicdog 時間: 2006-2-11 16:06
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作者: goldlighta 時間: 2006-2-11 23:19

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!作者: goldlighta 時間: 2006-2-11 23:22
