我還在等BUGATTI的1/8.
等到齊後,二台1/8一起拍才過癮!!:*
可列印查看
(1) 基本上測量時只是大概,並非最好的測量狀態,實際上應該會更安靜
(2) 將軍的試聽室並非完全吸音,所以跟錄音室是不一樣的

感謝小葉的說明.
剛剛自己又測了一下,把機器全關掉,35db.
在這裡,我也補充我的實際經驗提供給大家.
我的住宅上方偶而會有空軍的老母雞飛過上空(沒有民航).
所以當深夜安靜無聲時,或許臥室也有40db上下.
但,問題來了,臥室不是"恆時"40db,隨著外來的影響,也有可能提高到50db,甚至更高!!
可是,我的音響室卻是保證"恆時"35db,也就是說:
當"外頭打雷",有救護車的"5151",或者是"老母雞飛過",對音響室根本毫無影響!!
製作獨立音響室有各種不同的要求,安靜自然是要素之一.
安靜的好處說不完,要嚀聽"何大"所說的最大訊息量,安靜應該也是必須列入要求之一吧!!
安靜會讓系統功力提升很大一甲子功力.....
恆定也很重要
就像恆定光圈一樣比較貴啦.....

就結果來說,能發揮最大動態就非常不得了了.....
其中一個原因在於
將軍使用的是LP極緻動態的系統
另外一個部份也是類比與黑膠的差異,不過這是與生俱來的天限,各有優缺
基本上音響玩家不用拿黑膠與數位CD相比
只要將各自發揮到極限就好
From 李前輩 (Jett Lee)
Bugatti第一首Bach為1st movement of Violin Concert No. 1 in A minor, BWV. 1041 (2號是錯的)
這首巴哈也重編成古鍵琴或鋼琴的版本 (Harpisicord Concerto No. 7 in G minor, BWV. 1058.)
下次到李前輩那都會放給我們聽
The music is Bach's the 1st movement of Violin Concert No. 1 in A minor, BWV. 1041 (I guessed it as No. 2 which is wrong) and such solo instrument has also re-arranged to be played by either "Harpsicord" or "Piano" by Bach himself as Harpisicord Concerto No. 7 in G minor, BWV. 1058. Will play both of them for you when you visit my place (again) next time.
李前輩非常喜歡將軍放的音樂
I have to say that I was very enjoy the music* General played last Saturday.

:D
這邊有人做的小小的實驗可參考,但不一定就是正確的

Conclusions
It appears that the vinylphile claims are not as outrageous as they seem: LPs do have a usable dynamic range far greater than the measured dynamic range would suggest, and LPs consistently have higher relative dynamics over digital formats. But it is also true that LPs have higher distortion levels which translate to ultrasonic frequency harmonics.
The question is: is the higher relative dynamics of LPs an indication of higher accuracy, or are LPs exaggerating transients and dynamics? I'm not sure, and I would welcome comments.
If LPs have higher distortion and are exaggerating dynamics, it may explain why the apparent "benefits" of LPs translate even into LP recordings, and potentially explain why LPs of digital recordings sound better than their CD equivalents.
這個應該我們都知道啦
兄擔心太多了....
就聆聽來說,動態不僅要大聲有,小聲也要有 :D
http://my-hiend.com/vbb/showthread.php?t=2807
(1) Dynamic range (動態範圍)
系統「最大無失真的再生」與「不被噪音干擾的最小再生」的差距
將軍系統的範圍是目前High End系統中屬一屬二了
這是多方面因素均考量下的成果!
我們不同意開大聲就是代表動態大.....這是很簡單的共識啦!
能開大聲而沒有失真,各頻率均衡又完整的呈現,這才是厲害之處
在將軍那,我們都會不自覺的想要再開大聲一點.....
四因?
載媒訊息
電聲設備
空間環境聲能態
聆聽方式

我說的是成果驗收
就聆聽來說,動態不僅要大聲有,小聲也要有 :D
我常說:
騎著腳踏車指著FERRARI不夠快的人哪有批評"快"的資格!!
請到此為止,勿須研論,我也懶得像"何大"一樣在抬槓!!
想要最直接的驗證感受:
自己買套和我一樣夠大的空間,夠層次的音響系就能了解我在說甚麼!!
顶!:^)
玩HiFi如同上学读书,没有到一定级别,哪能理解高层次的表现:D谈到某些问题,如同瞎子摸象8)
將軍生氣了.........哇...............這應該是動態最大啦
THXman能有將軍系統的聲音再來討論嘍
動態僅是High End音響中的一環
form 李前輩
This is correct.
我必須先還原一件事:
李前輩是聽完在下的系統之後,對於某些只開大聲就誤以為有動態的說明,並不是在討論在下的動態只靠大聲!!
相信每個人都有自己的信念和看法
彼此互相尊重難能可貴
可是評論,甚至是建議
都應該是用自己的耳朵聆聽過才有說服力不是嗎
