"I can show you six areas in the JC 2 where I can change parts that will change the sound but not change the measurements"
Thats' a quote by Richard Schram, president of Parasound, on the JC2 preamp, the production version of the Blowtorch, designed by no other than the famous John Curl.
I think this is a good quote because while my electronics knowledge is not great (or even good) I know that this is an extremely good design by itself. But they didn't put it together by blindly choosing "well functioning" parts. The original design even used a specialist to choose the best sounding parts for the right purpose. So yeah it is obvious to a lot of us that it takes both measuring and listening to create a good piece of gear. But not to everybody, but I think people need to learn this. And in my recent experience with purchasing a second hand Mccormack amp, and knowing the designer's philosophy and history, Im now even more convinced to believe more in parts selection, layout, and a killer power supply than i do in pure design. But hey, what do I know.. we never stop learning.

類似話題老外爭論了幾千貼,不過總体來說,他們還是比這裡來得理性。音效與數據,誰兩極化的都是不理智。
LZ 想說作者應該說深入的音响制作而不止於原理上?
歐兄想說這本書就是講基礎,作者原意沒包括要教會讀者制作一台有个性的功放,所以LZ不應對作者不敬?
有人提到音响就是科技制作,那請你細看第一句英文意思,如果你認為你在音响方面的認知和知識能及得上 Richard Schram,那么你不須要反思了。
如果認為懂得電路就代表完全可以制作出一台功放的話,你或許是對所謂電路估得太高了,這裡誰能創新設計出全新電路來?現在音响所謂的電路設計,根來就是從已有的公式和理論的加減乘除計算笨工夫,就加上懂仿真又如何?這兩門玩到出神入化天下無敵了,不過原來還未做出机器來,可以發出聲音未?一切的自滿沾沾自喜還停留在顯示屏上,莫非現實中真的有像俠客行的石破天,看幾只蝌蚪都可以練上絕世神功?是的話恭喜你請留下聯系方法我馬上親身來供奉你啊。有心做好音响机器的人,我給你們一个良性建議,儀器基本夠用的就行了,盡快買一對好的音箱,對音响制作的幫助,絕對比一台六位半萬用表500M示波器還有什么函數信号發生器等等有著更大的作用。
玩音响不要只用固定視角對比法,應該用多點透視式對比,電路是手法,零件是手法,儀器是手法,經驗是手法,耳朵也是手法,全都應該共存,不要以偏蓋存。 |
