又在吵這永遠沒結論的問題.............

我也沒聽過，不過AUDIOHOLICS搞測試的那幫人每個花的錢都比我多N倍, 甚至比我房子還貴... :stupefy: 起頭的那位光是喇叭就花了5萬美金+...

我還是乖乖的在AMAZON買減價貨就好...

I'm so sorry, but I do not buy into 90% of the hype brought to us audiophiles by the commercial sector of our hobby and the home entertainment industry at large. My brother, an audio engineering whiz kid has proven to me what is real and what is not. Let me rehearse with you an example of how he does this.

We gathered up a 5 of our audio buddies. We took my "old" Martin Logan SL-3 (not a bad speaker for accurate noise making) and hooked them up with Monster 1000 speaker cables [ed. Monster Ultra Series THX 1000 Audio Interconnects] (decent cables according to the audio press). We also rigged up 14 gauge, oxygen free Belden stranded copper wire with a simple PVC jacket. Both were 2 meters long. They were connected to an ABX switch box allowing blind fold testing. Volume levels were set at 75 Db at 1000K Hz. A high quality recording of smooth, trio, easy listening jazz was played (Piano, drums, bass). None of us had heard this group or CD before, therefore eliminating biases. The music was played. Of the 5 blind folded, only 2 guessed correctly which was the monster cable. (I was not one of them). This was done 7 times in a row! Keeping us blind folded, my brother switched out the Belden wire (are you ready for this) with simple coat hanger wire! Unknown to me and our 12 audiophile buddies, prior to the ABX blind test, he took apart four coat hangers, reconnected them and twisted them into a pair of speaker cables. Connections were soldered. He stashed them in a closet within the testing room so we were not privy to what he was up to. This made for a pair of 2 meter cables, the exact length of the other wires. The test was conducted. After 5 tests, none could determine which was the Monster 1000 cable or the coat hanger wire. Further, when music was played through the coat hanger wire, we were asked if what we heard sounded good to us. All agreed that what was heard sounded excellent, however, when A-B tests occurred, it was impossible to determine which sounded best the majority of the time and which wire was in use. Needless to say, after the blind folds came off and we saw what my brother did, we learned he was right...most of what manufactures have to say about their products is pure hype. It seems the more they charge, the more hyped it is.

上網討論能紓解壓力阿 :p:p:p

尤其這種一對多的串，吵吵鬧鬧才熱鬧阿 :D:D:D:D

我是覺得沒有經過AB盲測的結果, 說有差我都當他差在屁股啦 :laugh:

有很多人其實過18khz之後的聲音都聽不到了,
但他會跟你說WAV和MP3有差, 而且差很多......
AB TEST後發現他完全聽不出差別 :think:


光碟機讀取是個fifo的東西, 所以jitter會非常大,
讀正確一點都不難, 難的是每次送出的東西時基都一樣, 那是比不可能的任務還不可能.
jitter這東西無所不在, 不管數位還是類比,
類比換線會造成聽感不同, 有很大比例正是線材特性對波形造成影響
廣義的來說波形的前後位移變形也可以視為jitter的一種

數位訊號的jitter單純造成時基問題, 而光纖訊號的jitter普遍較同軸訊號要大,
有很大的問題出在光電轉換器上, 線材的影響反而其次
所以很多玩數位的人還是比較愛同軸的道理在這
要說PC有這問題, 那CDP也有一樣的問題
所以前面幾位就已經說了, 要打平應該是沒問題, 要講超越就有點難

理論上, 數位音訊都應該在進DAC前做re-clock的動作, 將jitter影響減到最小
呃.....但我不知道目前有做re-clock的機種都是怎麼實做這一塊
所以還是請學有專精的前輩來解說一下好了 :ase

標題應改為

"你覺得什麼時候電腦播放音樂的音質可以超越LP？"

myav哪幾位玩家,是用LP的大系統在比對的...

超越cd好像不是那麼困難...

你信不信來個兩組條件都一樣的音響,然後由同一人聽,還是會有人說那組好聽. :stupefy:

照例，這串多是一些老骨頭進來！

我曾經看過有人比較同一款式的耳機, 都是新機, 差別只是顏色, 然後顧客堅持黑色的比銀色的好聽...

就是有人宣稱他可以聽出傳輸中lose掉的那1bit訊號的差異性啊。 :laugh:

搞不好兩款耳機有誤差囉∼就算同款耳機每一隻多多少少還是有差別吧＠＠

另外網路的評論看看就好

最重要還是要去聽

要不像那個冰凍23天的蛋糕還不是一堆號稱美食家被打臉打得很慘...

連新鮮不新鮮都吃不出來評論美食公信力自然大下降囉！！
