[#21] LOGIFULL LDac1000有人玩過嗎?    
如果睇過newclass d 既鍾,又睇過有咩機會用,點飛線,等等,就唔會話呢部機點飛線,即係睇開以前廠機,咪覺行Module土炮
行板唔飛線又唔一定好,係咁人人做條RCA 用 flexible flat line,洗鬼玩咁多野

RCA頭有d似澳洲佬kle隻頭,個concept係要用一條線咁去connect,唔係成個頭去connect,越厚越大唔係好事,即係飛左個RCA頭,直入條Duelund銀24ga 去接就最正啦

講開內部飛線,以前玩過部Luxman DA-07就真係經典
多到真係一個點,一開箱,嘩左聲

上番張以前舊相

如果講 internal engineering, 咁日糸機同歐美係走唔同的方向,用浪漫的說法;日糸機是感性的,歐美是理性的結構,下圖是一部 80's年代尾的經典。

或者日本人在engineering方面係比較現實,例如下圖這部安立Anritsu,佢在有需要的地方才會用 die-cast/CNC 的方法包著電子零件,其他地方都是飛好多線的。

#23, 哩部米係wadia 9 dac的內部羅,井然有序,一派大廠風格。就算係日本大廠出品,即使要飛線,都會有一套走線手則,飛線得來好整齊及有序的,不是在乎線究竟有多少,而是在乎條線如何走法!但哩部日本dac的內部佈局, 一看就好明顯係好日本diy個種feel, 佈線完全係天馬行空,飛象過河個隻,完全沒有日系大廠,例如Sony,Accuphase個種佈線風格。明顯係蚊型企業的作品,好唔好聲我無法得知,但單看佈局,好明顯係沒有考慮過線與零件之間可能產生的潛在互相干擾的問題羅。

望落線同線都唔算overlap, 講大廠咪方方便便整塊板,看似整整齊齊,走線咪仲近, 圖中起馬見電源同signal都離好遠

呢部更唔似大廠,只睇wadia鍾個part點都去唔到newclass d level,佢要incorporate更好既鍾,細廠做到既可能性大d, diy仲大


廿年前講大廠出品意義大d,而家歐美都module化,方便大量生產一定係一塊板過
如果胆機,你見到有板都唔想買,話要飛線,要搭棚
利申,我麻麻日本聲Accuphase等等既機

人哋師傅用一個非常傳統嘅設計,注重電同震動處理。日本旗艦足料金屬機箱,足料缐性牛。數碼方面簡簡單單,2聲道用2塊板,全平衡,又只有一個數碼input,其他USB Toslink師傅唔會用,所以唔放上去,可以專注啲。Modular design 飛缐就一定架啦。唔知點解日本人至鍾意飛缐,可能用多啲銅,多啲胆味,啲聲厚啲。

但我覺得機箱冇必要咁貴成本。如果唔係用laser drill,就用CNC機器搞好耐先做到出嚟。Anyway 日本文化注重包裝…..

最緊要好聲同好靜…..

Class D clock is defined by ITU for synchronization of telecommunication equipment and communication protocol, normally ITU's class D clock is around 5 nS and the requirement is varied for very high speed data link such as those 100GbE...to TbE. Not the highest standard but sufficient of ITU. The highest standard is NIST-F2, that is around 0.1% of 1nS.

Haaha...

OK.. Is those new clock.. By some new class D circuit..


Not a clock by a brand name called "newclass"


Haha I am. Such. A stupid reader..

can i look at it at a dummy manner..., if 192K over sampling... ,we need soemthing at 0.000000X sec range accuracy ?

if something at =/-1% of 1ns = very sufficient for the task ?

HaHa

hi lam lam

can i look at it at a dummy manner..., if 192K over sampling... ,we need soemthing at 0.000000X sec range accuracy ?

if something at +/-1% of 1ns = very sufficient for the task ?


haha

haha Go4War..forgive us to off topic...Blow water...haha

Friday WFH..is boring..........


keen to know some of those comment about some of those OLDER Japanese DAC..

Haha, this seems to be ordinary crystal clock, diy'er normally like to have ocxo, GPS or even atomic clock for their audiophile gears, right?

Yes, but it's OK for vintage gear, Wadia may be classified under this category as well. Vintage sound is always romantic, just like R2R, FM radio.... etc.
