world premiere of the new Airblades! good job! congratulations to the owners! Fine integration with cutoff frequency, output level, and time alignment selection already done? healthy envy!
Tue I went to AESW experiencing the new height of the performance after hours of fine tuning by Chris. The first thing I noticed was a much better 3 dimensionality of the treble details, instruments having a more prominent characteristic on the treble compartment are visually locate-able.
During the last 2 times when I was listening to air blade, I could only feel the energy is packed filling the room creating an unprecedented sensational feeling... At that time, I can only appreciate the augmentation part without a clue on how it would mingle into the treble horn of the Wagner signature
My hifi instinct told me Chris has further advanced the integration and suspect the treble horn was disabled leaving only the AB serving the 3,500hz and above
My instinct was partially correct as what Chris had done was to reduce the sensitivity of the treble horn in order to match with the sensitivity of the AB. The seemingly 1 source, instead of 2, produces the solidarity and vividness on brass, winds, horn alike instruments. Elsewhere, the replay of 王菲的「約定」 had me surrendered‼ I know no one can play this and the Karajan live orchestra at such realism without the AB.
I will follow Chris to use Gaia speaker cable with AB as genuine partnership. Again, trust the experts and your ears‼
The Da Vinci Grandezza cartridge high output version (0.26mv) from Switzerland. It is actually still a low output cartridge but the original version could only deliver 0.17mv. This exquisite reference cartridge reveals extremely colourful tonal colour in a neutral sense. I will rediscover it soon.
We conclude the best positioning of Air Blade is to align it horizontally with the tweeter of the main speaker on the outer side of each speakers. The result is a more impactful “panorama” perspective as though the “feeling of stage” extends beyond the left and right wall. It is not a only matter of perceived width, there is simply more content of everything, including energy. Positioning Air Blade this way requires a tripod on both channels. It is worthy of taking this move.
Only one pair of Air Blade is working in the picture. We compared back and forth.

這個經驗真係要分亨一下。當我換上了Ikigai Audio 的Kangai interconnect from Zanden 1200S phono to Dartzeel NHB18NS Mark 2 preamplifier之後,Air Blade 氣刃的 volume 要由-6db大幅上升至0 db,而且還要將它推前到和Cessaro號角高音發聲點對齊。
那又為什麼我原先要把volume減6db呢?我更要將它推離號角高音後3-4寸。原因是「高音」過量了。以眼代耳,假設Last in是所有問題的根源,掠過理性分析,是發燒友常態。今次我也跌入了此自設的圈套。
可是Arthur (Air Blade設計師)從technical 的角度曾提出了質疑 - air blade 是追不到Cessaro 的號角高音,為什麼還要被推後那麼多?而且還要減6db? Air blade -6db 差不多是冇聲。
由於Argento FMR訉號缐和膽前Rivierlab Lab APL SE和Engstrom ARNE膽後級所產生的協同效應,並不等於會在Dartzeel主導的系統重現,反而銀缐和Cessaro高音號角的超高靈敏度,導致高音能量偏多,遮蓋了中音。換了Kangai訊號缐之後,問題立刻解決了。Air Blade 音量要提升到0db,我亦無需把超低音的crossover提高,我還要把它推前。一對訊號缐換了,便推翻了所有之前的涵數設定。
Mr Zanden 所批評的也是這個現象。而直師傅認為中提琴不清楚,所以把Air blade toe in 了 one degree,原因也是一樣,只不過他用的言語和Mr Zanden不同。至於Uncle Ray的角度,是因為他眾多reference vocal錄音好多是泠乾的聲缐,高音能量多了,又特顯了蒼涼無比的感覺。(當年和己故好友EDDIE,常常討論為什麼中音厚潤就等於音樂感豐富,那麼加拿大和北歐偏向冷的歌聲,又怎樣才算有音樂感?後來,Dalby Audio Design開發的Eddie power cable是朝著此方向開發。)
那麼我是怎樣知道問題出於訊號缐?這取決於你對自己廚房和食材有多了解。我已經代理了Argento二十年,FMR的強中之強,就是中高音以上的能量。氣刃是最後進入,所以問題焦點放了在它身上。同時,FMR仍然是一對好缐,只是不適用於此系統。切勿用ABAB比拼互揪的角度,去總結輸嬴。分析一件事,一定要先理解背景。
這次的case study令我了解到更多。第一,每個人聽同一樣的樂曲有不同的priority。第二,大家經常用不同的language形容同一件事。第三,失真和音染尤如糖果,你可以喜歡它,但同時你又能理性地知道它們是假嗎?真、善、美,便不是每人所追求的共同目標。第四,分析各方意見後,要思考清楚是否適用於自己的哲學。第五,常常抱著永遠有空間再進步。
總結:不要死守一門學派,因為時代科技不斷進步。新科技需時領悟,並不代表它不能勝舊。破舊立新是歷史常態;人不喜歡面對變化,乃是人性的基本。尊重傳統卻是永遠的美德。所以傳統和科技進步並沒有矛盾。
一切在乎於個人心態的修為。
然後一曲羅文的「好歌獻給你」,Chris示範了如何調整了subwoofer 的 input gain 只有0.25dB,便能把當時羅文的陽光勵志的唱腔及情懷完美地呈現。當所有parameters都調校到洽到好處時, 所有不同類型音樂的神髓都能演奏出來,包括小提琴家拉弓的力度, 鋼琴的份量,及各樂器聲部之間的平衡等, 都到了上環前所未有的高峰。
最令我難忘的是「國王與我」一曲,我在此應該聽了此曲不下5次,但今次不再只是舞台的華麗感, 而是連Anna與國王對話時的腼腆情感也表達出來,細膩的感情不像一般系統那種無病呻吟或過分喧染的表達,而是內歛又自然流露。
我的朋友今次完全對horn喇叭的印象改觀, 他說上環的堂音已經靚到不能形容, 真實感很誇張,他十分欣賞這套系統。
Chris又一次突破自己,絶對是職人唱片演奏家!
這次探討的主題是超低音的調教, 測試曲目是「羅馬之松」第四樂章。剛開始,項羽超低音的分頻點是70hz。PT解釋, 由於Cessaro Wagner Silver Signature的低頻於70hz左右開始Roll-off,所以按數據的理解上應設定為70hz。當曲目播完後,Albert兄提到後段的鼓聲能量有點不足,PT思考了一陣子,然後把分頻點提升至75hz,然後再重播Pine of Rome 的 4th movement。能量問題立刻已經解決,但Albert兄認為畫面有點亂和模糊。然後PT將分頻點調低致73hz,結果令大家震驚。
由原來的70hz,輕輕提升了3hz之後,竟然可以把整個音場提升, 連帶高音及中音都更清脆、總體透明度更高。之前略為模糊及能量缺乏的鼓聲,變得更清晰,而且能量更強。
我吸收了以上的知識經驗後,晚上回Studio重新調教自己的超低音。方法如上述差不多, 但出來的效果也是令我非常吃驚。想不到小型書架喇叭配上一對超低音,也能與一般座地喇叭爭一日之長短。
這次的經驗十分寶貴,不但學習到音響的技術,更了解耳聽為實的道理。器材再好, 也是由人耳聆聽。PT確實是我所認識的音響發燒友之中, 最有要求的其中一人。
