Sorry, there is no need to understand all the technical details as we are not going to design a HiFi equipment or component.

I am just an audiophile with specific knowledge to select and appreciate different performance of the gears to fit my need.

On the contrary, from most of your expression, you just "see" or "watch" the component(s) and will judge the performance.

If your way is correct, there is no need to have different classes of HiFi gears from different brand.

All the audio companies just need to employ electronic technicians or engineers to do the paper work design.

What a funny argument !

Anyway, I am not going to spend further more time to discuss with you on the issues as it just wastes my time and effort.

You go your "paper" reading way and I go for my actual audition way.

I believe most of the members of Hiendy knows what they are going to trust or believe.

如果一個人聽過並熟悉了運算放大器4558﹑5532﹑OPA2604﹑ AD797﹑OPA627在HIFI中
的聲音﹐當他看到你那部機用4558作輸出時﹐他還用聽嗎﹖當他知道那種DSP非常易
因裡面接觸不良引起很多問題時﹐不用說要他聽更不會買﹔知識重要﹐經驗更重要﹗
人才跟鋼材一樣﹐要磨才鋒利﹐但有些一磨即鋒利﹐有些磨極都不利。

今天賣的電腦肯定比幾年前的電腦先進而且便宜很多﹔“天下第一刀”的鋼材好﹐
一磨即鋒利﹐基礎好而已﹔430不鏽鋼刀跟440C不鏽鋼刀的分別而已(不懂查GOOGLE)。

以前有位秒殺級的音樂家是聾子﹐只會寫及看音樂﹐發燒的人不知道﹖

There could be thousand of deaf musicians, but only one made it to the top.  His masterpiece was appreciated and judged by mostly common people who does not know music and certainly not electronic engineer.   BTW, most people judged thru live performance, not thru electronics.

There could be thousand of electronic engineers in the HIFI field, only few make it.  So please 磨 harder, who know one day when people (not limited in this forum) talk about HIEND, they associate the term with you.

Not totally agree.  From engineering point of view, LINN DS circuit is indeed quite advanced.

Linn uses all surface mount components to achieve fast and low noise power delivery; it is more advanced than traditional through-hole circuit.   Traditional circuit is not suitable for high speed circuit because of long part legs.

Linn uses lot of local power regulations.   Three next to the signal processor, another two next to dac section.   The main one seems quite sophisticated too.   With so many local power regulators, the main power is switchmode isn’t really relevant.

All capacitors are tantatum type (brown color) and some expensive polymer caps (black color) around key components.   These polymer cap makes Blackgate like stone age parts!

Once use surface mount, it is not easy to tell the part quality and cost.   Film cap by Wima or Epcos look almost indistinguishable from cheap stuffs.
Attached picture is Wima SMT cap.

Why some highend manufacturers still use traditional red box Wima cap and like even through they know surface mount is much better for high speed application?    Because audiophiles all like big parts.   Big parts look more valuable to them.   Those manufacturers choose to use big and colourful parts by their eyes rather by their heart & brain.

Can you conclude that SMD is better than traditional electronic component due to shorter signal path, lower distortion and higher speed?

Crixus

單睇晶片就知道好唔好聲? 要知道同一部機, 唔同環境, 唔同電源, 出的聲都好唔同, 既然連parts, design 都唔同, 單睇晶片就可以落總結, 唔係下話?

Better to phase it as "SMD is better suited for for high speed application than traditional circuit."  
And depends on speed requirement, traditional circuit may or may not be able to meet the speed requirement.   

Some traditional circuits use partial SMD to achieve speed requirement for particular part of the circuit.   e.g. SMD around processor only.

Modern audio devices use high oversampling and complicate digital processing, speed requirement will become higher and higher.

理性討論當然有助於互相分享及學習，而分享著重於互相尊重。能夠接納不同意見，才會有進步的空間。對於持不同意見的人（及其意見）作出武斷批評（在未經核實的情況下），我看不出對大家有什麽益處。

根據刀兄的理論，一台優秀Hiend Hifi器材的設計者只需是電子工程師，並不需要擁有任何音樂知識及修養（因爲他根本不需要聆聽自己的產品去判斷產品的好壞並作出調教）。老實說，對於一個缺乏音樂知識及修養的人要設計一台優秀Hiend Hifi器材，本人覺得成功機會不大。正如一個對音樂一竅不通的木匠要製造一支音色優美的小提琴或有相當質素的喇叭，我相信難度也非常大。

最後我想說，雖然每個人聼Hifi的目的不一樣，但聼音樂無非是想放鬆心情。聼音樂亦有助陶冶性情、提升個人修養。奉勸刀兄多聼音樂，少作無謂的口舌之爭。我相信如果刀兄有什麽有建設性的意見，大家是很樂意聆聽的。

本人並不是什麽品牌的代言人，只是路過有幾句話想說而已。如有說得不對的地方，請多多提點。

你的意見很好﹐‘理性討論當然有助於互相分享及學習，而分享著重於互相尊重。能
夠接納不同意見，才會有進步的空間。’
但中國人有多少個能夠接納不同意見﹖出名的只有唐朝的李世民而已﹐中國跟歐美
的分別在于獨裁與民主﹐沒有言論及出版的自由﹐全民腐敗﹗上面最高領導人整天
要什么改革﹑創新等也無用﹐政治體制及教育體制是中國沒有實際創新與實用的發
明的主要原因﹗

一台優秀Hiend Hifi器材的導演是公司部門經理﹑構思者應該是市場部﹐電路設計
者只需是電子工程師，工廠打樣試聽就需要擁有音樂知識及修養的幾個人與不
同年齡的人去聆聽產品音質及音色的好壞並跟電子工程師一起作出調校﹐由電子工
程師調換不同的部件讓他們試聽﹐用什么價格的材料還是由公司決定（以最少的代
價穫得比較好的效果及工商利益）﹗還有軟件工程師﹑美工做外觀的設計及包裝設計﹑
塑料及五金模具工程師等﹐你的看法是否片面了一些﹖

根據我已知電路聲底﹑零件的聲底及其性能好壞﹐為何不能判斷機器的性質及音效呢﹖
如果不能﹐還有那么還有那么多人“打磨”ＤＩＹ﹖
