Hi Ken Sir,

I have bought MA6700 with focal 1008be last week, it sounds so well even it is not yet fully "open sound".  my issue need your help is:

i used to download songs fm iTunes as it is conivence to me.  however, i found and understood that the sound quality is much better when i play flac format or rip the cd to aiff 192k songs.  i know that it is the norm, however, i found that i am hard to leave iTunes as it really easy to find the song i like from iTunes, which hardly found from the HD site, and i am really don't want to go back to use CD...

is D100 can substantially improve the sound quality for downloading songs fm iTunes and instead of using the dac in MA6700?  if so, i will buy it immediately. or i must buy Cd with Mc's CD player?

pls let me know

thx

Tony

Dear 師兄,
若以暫時的軟件處理技術,除專業級別外,一般我們可以從正途購買得到的音樂軟件,基本上和 CD player 直接播放出來的仍有一點距離,這不外乎是軟件的製作質素平平之關係,而若從 CD 中拷貝到 CAS 硬碟中則需要視乎你所擁有的音樂處理軟件平台有多高的水平,而所拷貝出來的複製音樂大多都因在電腦 CD Rom 拾訊要有所誤差,因而得出來的效果即使升了 bit /kHz 也是會比原本的 CD 種差上不少呢,這就是拷貝的隔代失真,因此可見為甚麼連專業的母帶拷貝也要加多一個 Remastering 的程序去處理以上的問題。

然而,D100 內置的 DAC 級別是比起所有 MA 系列的還要高班 (8 核心 Vs 4 核心) ,所以得出來的效果的確有非常大的分別。

thx very much for your prompt reply, Ken sir.

As your professional description above, the root issue is still on the copying process from CD to my Mac and/or the source i download, thus even with improvement from D100, using CD player playing CD is still the best method, right?

In addition, how about using turntable?  The McIntosh one looks so classic but fancy, it is an art!  As over 30 years didn't play LP, and seems it is returning become popular, do you think playing LP will get even better quality of sound fm CD?

Many thx

One more questions, Ken sir

As my compo is just running-in for a week, i already find that it is turning from without solid sound positioning to now getting better.  the vocal always in front of me at the middle; when i move the speakers closer to me, the vocal stand at the middle but lower (around 1ft tall); when i move the speakers closer to the wall, the vocal sound at the middle but upper (around 4ft tall), it is so amazing!

However, the sound stage is limited between the distance of two speakers (around 6 fts), and it is also not very 3D, the sound stage is pretty flat (but it is better when i play CD / FLAC file).  I would like to identify the key issue of causing this, is it mainly caused by 1. not yet run-in, or 2. the source (CD/FLAC/itunes...CAS) issue, or 3. the connection wires, USB/optical/speaker wires, or 4. it needs to toed in?

Sorry for so many questions!

I would say it is your speaker placement and toe in angle vs your listening spot. Sound staging will change dramatically if your speakers are properly set in your room. Also, move the speakers away from back wall or when audio cabinet is set in between, by doing such will leave a space with no objects in between speakers thus should enhances overall 3d effect. Always leave space behind and between the speakers.

Dear 師兄,
以現階段的科技來說,論評所有民用重播之平均質素效果,可以說 LP 是一面倒的比 CD 好聲,即使一套較廉價的 LP 播放機所出來的效果,亦竟比一些高上多部的 CD 機來得還要令你聽得舒服受落,這是因為在物理之上它並不需要在儲存軟件上作出頻率還原與修正的動作,若暫不提存儲與錄製工序, LP 只是單純的拾訊再放太,再由 Phono amp. 擴大至適合 Pre amp 使用,只要夾膠碟之毋盆做得好,重播出來的音樂效果也就自然的好 ,這對用家而言是最簡單易得的最佳途徑,相對數碼編碼儲存至 DAC 解碼出來除了要面對音頻數碼轉換、編碼時的數句運算誤差情況外,住後所有的燒錄儲存與拾訉播重,當中之程序也必定遇上多樣不同的誤差因素,導致不能接受的音效結果,因此所有生產數碼器材之廠家,都不斷致力在數碼解碼規格、頻率波形較對重組與 DSP 修正技術之上推陳出新,希望達到最準備、最傳真的重播效果, 當然 LP 就並沒以上的一大伙問題了
然而,LP 以住之所以在時代巨輪之下萎縮,而 CD 則爆發冒起,其原因只得兩個字 "方便" ,而且在數碼化之後很多不必要的干擾情況就自動消失了,正所謂 "快、靚、正",可是時至現今卻有更 "快、靚、正" 的面世,更是成為潮流,那就是 CAS 多媒體儲存播放器的玩法了。   而相反地 LP 則成為了另一個時尚的品味潮流 ,特別是對音樂質素有所要求的發消一族,不只是本地如是,甚至在外國近這一兩年 LP 的發展卻逐漸加快,今年度英國流行音樂軟件生產統計上,LP 軟件生產量比去年的一下子急升至兩到三倍產量之多,證明市場潮流正在轉變,更是歷來少見的現象呢。

Thanks Ken sir.

Yes, even i am not having a million-equipment, it should be the way to go if i really want to get a better natural sound quality.  Hope i can find those songs in LP version, but it is very rare in HK!

Dear 師兄,
現在你所遇到的如 中位平坦沒深度、高頻延伸不夠廣闊、景心偏低 .....之類等等,都是一個最明顯、典型的房間問題,相信與器材硬件、導線等的關聯性較低(若不是使用太差質素的,或是錯配了的話),因為不同的房間各有不同的聲場特性,處理房聲效問題是一門十分有難度、複雜、專業性的工作 ,因為當中涉及了我們想像不到的那麼多變數與問題。 當然,小弟亦是不能相信單憑在此書其三數十個字就可以把你說個明白究竟,要設置好一套音響器材在家裏,效果要完美理想,第一件事應該是先找出罷放喇叭的最正確合理位置 ,當然要切合家居正常生活,除非各下設有獨立的 Hi Fi 爆房,那當然可以天馬待空為所欲為亦沒有相干 ,但是由於香港地少屋細,一般家居都是尺寸狹窄蠱怪,更有鑽石型的大廳設計,令人有時無所適從,那唯有大膽一點多花些時間去慢慢嘗試、比較,取捨一下最適合的擺放位置
然而,當你找到最佳喇叭擺放位置之後,那就定立了第一個調較的據點,這個時候就可慢慢去發掘一下房間中的其他音效問題與聲場特性,好好地調整所有配置從而去盡量協調這先天的因素,若你更換了喇叭之位置,那先前你所做的一切就亦要重新一次了。

Dear 師兄,
很同意呢 ,不過現在也開始慢慢的多起來了,連一些流行歌手也去推出 LP 版本的專輯,而且在一些常見的 CD 店舖中也開始偶有 LP 銷售的蹤影,這的確是件很有趣的事呢
