其實啲所謂 HD DSD PCM 4K 8K format 都係 misleading。最好睇返 bit 數或者 MBPS million bits per second 比較實際。如果聽碟，SACD 有 5.6M，CD 1.4M，好多所謂 HD 只有 320K。Video 更加搵笨。例如 Netflix Now TVB 話自己4K，但係只有 10M，睇 BD 碟就有50M 之上。佢哋係 audio 同顏色同密度做手腳，人哋點點有唔同訊息，佢就每2點就中間個點做平均數壓縮咗佢，方便輸送同儲存。

唔夠 bits 點算？ Sony 電視話佢個 AI 升頻好勁，乜嘢唔夠稱，都比佢整容加假 bits 整番靚靚好少人睇得出。我自己個 SACD，N年前以經識得同 SACD CD 升頻，全部 DSD x2 加 bits，佢話聽 CD 都係好正。Anyway 有人話有分別，有人話冇分別，仲有人話 low res 多啲感覺添。

講咗一大堆廢話只想話碟比較可靠啲因為佢冇假 bits。所以要求高最好考慮買碟機。

其實我對 睇片方面要求唔高，有部 BD 播下片，加條 藍芽 soundbar 俾老虎聽 CD 就已經足夠。

各位 師兄

部 DAC 有 USB B 接口，我駁 ipad 上 Tidal Hifi Plus 聽歌。

我冇乜 SACD 收藏，但都有少少好奇想知 DSD 究竟有幾正，不過尋日係網上爬文，知道 Oppo 只經 HDMI 輸出 raw DSD 訊號，但 DAC 方面又只有 I2S 介面，似乎中間要有份轉線器先可以成事。

再深入啲就去到粒 DAC 晶片上，好似話 ES9039Pro 係食 DoP 訊號，而只有 AK 先食 raw DSD。

到呢到我已經迷失了 !

樓主部 DAC 有 USB?

Example sacd transport with I2S via hdmi

睇碟機睇唔到4K。
聽碟機聽唔到SACD。

睇碟機個 video circuits 好嘈，點樣隔離，點樣用料上乘都係冇用，因為 noisy 嘅 video components 太近 audio parts。所以如果係聽歌要求高，一定要分開。即係話，2個問題要有2個解決方法先得。

識得朋友買台 SACD 機嚟尊登聽 HiFi 展隻 SACD 碟好開心。如果買台 SACD 入面隻 DAC 最好可以 USB 解碼埋電腦入面啲歌仔 files。

＞＞#157...影、音已分家.....或者買部可以放 SACD 嘅 CD 機
------------------------------------------------------------------
Up下

影、音分家=有高要求

可以放 SACD 嘅 CD 機=SACD機=esoteric, marantz, denon….

如果要求不高 Panasonic 820 睇碟巳非常 ok, 投影就最好考慮 9000

現今最 popular 是用 HDMI 出 I2S, 揾部 transport 有 I2S 就可出 sacd 的 DSD , 應好過 105 analog out 播 sacd
獨立 純音樂 transport 多贏全能機
要 Sacd. CXC 只是 CD

多謝各位師兄回覆 !

現在影、音已分家，係估唔到部 DAC 咁好聲，而且同時欠缺咗部影碟機，所以可以考慮買部影碟機或者買部可以放 SACD 嘅 CD 機，唔知邊個 option 會適合啲。

一點要留意光纖出吾到 DSD 信號, I2S 可出 DSD
如有要求丶可能要玩 I2S

又 你部 DAC 有 I2S hdmi, 而 Oppo 可加 I2S hdmi out , 做 transport － cd及 sacd, 現sacd DAC 一定靚過 105。
朋友用 AIM hdmi 連接 transport/DAC 有滿意校果

Panasonic 9000, 一部過丶睇戲丶cd transport 都全贏 105
9000 個 HDR optimiser 好正
Sony 好像不対應 HDR10+, 而 Panasonic 對應所有 format
自用有Panasonic 820 及 9000， 9000 黑位分析力贏 820， 做 cd transport 都係 9000 好點丶但都係吾夠音樂味！

：I used to buy UHD 4K from Amazon US, adapting to Sony BDP 4K to Sony A80J TV
Except no Chinese subtitle for some selected BD, all running well and nice in sounding

係咪要睇 4K BD？ 係就 Sony BDP 睇碟 + 玻璃光纖入 DAC 聽歌。如果唔係，比返 Oppo 入 DAC 聽歌。用 DAC 聽，再比玻璃線隔一隔，會靜好多。

The story is like this

I’ve an OPPO BD105 as CD player in HK, and of course, it was also connected to my OLED.

After moved to oversea, the OPPO act solely as a CD player and no blue ray for home video.

Recently, I’d acquired an SMSL DO300 DAC, the sound is no complaint at that price range, which makes me rethink the current home hifi and video setup, should the OPPO goes back to the video side or remain as a CD transport and buy a UDP for video setup instead.

雖然係好聲，但唔好買個CDP專登聽 CD。如果有 CD，建議買過平平哋嘅一手或者二手 DAC，例如 Schitt ，插入 BDP聽好過。要買就買 SACD player。
