看完版主“打磨”完馬記ＮＡ７００４﹐不用聽就知秒殺了ＬＩＮＮ的同類機。

剛ＲＩＰＰＥＤ了一個24BIT/192K的音樂文件﹐用硬盤直接插入1080P播放機播放﹐
用光纜接昇頻解碼行到192K﹐由于解碼只有24BIT/96K指示﹐但96K燈亮表明24BIT/192K　
ＯＫ﹔因為1080P的機器光纜輸出必須支持24BIT/192K才可以接7.1功放
用CAT7網絡線下載播放時只是44.1KK燈亮﹐可能CAT7無法滿足192K的要求。
請教版主有沒有用我以上的方式跟ＬＩＮＮ及馬仔的比較過﹖那種方式好些﹖

好厲害

我都諗過，但要成塊layout 過。
CS4398 DAC support.

有十條友要至可為本。
會照抄SA7 果份野。

可唔可以整個平衡輸出會唔會更PERFECT?
AND
HOW MUCH FOR MODIFY?

Final Upgrade

細果塊穩壓俾DAC電源

大果塊俾Analog HDAM

重未整完，星期二晚繼續。

Linn DS 要下一個firmware先support party mode, 到時可以同一時間stream去Marantz同Linn。iphone介面可用返Marantz或SongBook。Plugplayer還未支持party mode。

1. Upgrade ID, MAC address
2. Serial no.
3. Hand on $400 cash to counter

Wait 1 working day

    恭喜恭喜, 歡迎加入7004小家庭

昨日逛友誠，遇到以前識的一位SALES，一口氣買了NA7004(還是香檳色, 價錢特惠)，1條同軸線，一部MUSICAL FIDELITY的M1 DAC，前天還買了一部BUFFULO NAS, 1.6G，2BAY 1000BASE-T + 2TB, 一部大功率WIFI發射器,
現在是萬事俱備，只欠東風了!
KK SIR的欣賞會何時舉行?

Thanks. KK Sir!

Why,
1. DA CONVERTER 有的用CYSTAL CS8414, CS8416, CS8418, 哪一粒好?
CS841X is digital receiver.

2. SRC 蕊片又係哪一粒較高, 好似係4193, 4198....
Same.

3. PCM 有1704, 1706 1798, 1795, 1796... 哪一粒較高級?
PCM1795 is 32bits DAC.

    One 24/192 flac 5.1 feeding from coaxial to NA7004 (the file is 6.8GB in size)

呢排上網惡補DAC NAS 知識，有下述問題搞唔明，請教KK SIR及各位師兄：
1. DA CONVERTER 有的用CYSTAL CS8414, CS8416, CS8418, 哪一粒好?
2. SRC 蕊片又係哪一粒較高, 好似係4193, 4198....
3. PCM 有1704, 1706 1798, 1795, 1796... 哪一粒較高級?

用乜入？

FLAC only 食96Khz file

為何我的24/192 flac track (5.1) 輸送到 NA7004 變成 96Hz?

Why,

SSP LHE quote NA7004 = $5,600

About remote control, I　can browse my NA7004 via a browser doing simple control. But my phone can barely connects the machine. Besides. I think Windows Media Centre is a kinda music library which I can always stream some music and video using PS3/N3. Well I do not have this luck for my NA7004
the problem was solved

This is Marantz official price for standard reseller.

Last night, I went to KXX in Time Square shop, they quoted me $6300!

新机才有，又加少少价。

舊机啋你有味。

Marantz UK announced to offer free Airplay in March...so I can wait and see.
I paid 5.5k

1. How much?
2. Will you upgrade to AIRPLAY?


PC output only PCM to optical output socket.
i.e. PC CPU convert FLAC/WAV/APE to digital PCM format.

好多人期待 NA7004 未摩 VS NA7004 終極全摩
