[#1] CD quality no worse than High Resolution Playback My personal listening have always parted with CD quality playback and I'm pretty much happy with the experience. This is in contrary to those who have firm belief in high resolution tracks like 24/96 or higher resolution and DSD audio, on which people have more pleasant listening experience and opine that they have better sonic quality. Listening is subjective but properly conducted blind tests should reveal the sonic differences between recordings of different formats. It's to my surprise that a survey done by two AES members from Boston Audio Society indicates that listeners could not distinguish high resolution audio from CD quality audio. Have a look at the survey: http://www.drewdaniels.com/audible.pdf |

[#3] CD quality no worse than High Resolution Playback When CD was launched late 80's, it was considered unlistenable. Most CD players then had 4x oversampling to smooth out the digial sound from 16/44 source (which is 1.44M bit data). Nowadays, because of Apple, from the iPod days, people keep saying 330K bit is already high resolution, and when 1 people says it is, the other people would agree it is too, because they have not heard anything better as these people seldom pay for a CD, not to mention a LP or a SACD, nor have the hifi gears to tell the difference. This is so sad >_<. |

[#4] CD quality no worse than High Resolution Playback If files ripped from CD losslessly, they should not be better than CD because all data are from CD. One may argue that real time data pickup from CDT/CDP should not be better than audio files which are securely or accurately ripped. However, the fact is CAS/FAS are even more subject to various culprits of causing suboptimal sound reproduction. CDT with DAC or CDP are relatively more simple, despite the fact that they would have more tonic characteristics added into sound reproduction , making different tastes. But that doesn't mean lower resolution ability than FAS/CAS. In my case, I treat FAS/CAS as another sources for the ease of sound reproduction, rather than a pursue of higher sound quality. You may say because one need to invest more time and $$$ for higher sound quality but if so, why not just keep CD and LP as sources? 最後修改時間: 2013-05-30 18:26:24 |

[#5] CD quality no worse than High Resolution Playback 簡單說一說這個研究。 很多人說CD音質不及SACD/DVD audio 24/88 或更高,所以有工程師做了一個為時一年多的測試,用的是ABX測試法,AB分別是CD及SACD/DVD,X是要測試對像,測試者要說出X是A或是B。 結果是在554次測試中,只有276次或49.82%正確答案。這其中有467次測試由發燒友或專業錄音師進行的,246次或52.7%正確。 研究結論是在聽感上,CD與SACD/DVD並無明顯差異。 http://www.drewdaniels.com/audible.pdf |

[#8] CD quality no worse than High Resolution Playback 何必講d唔講d? "The “best” listener score, achieved one single time, was 8 for 10, still short of the desired 95% confidence level. There were two 7/10 results" http://www.drewdaniels.com/audible.pdf |

[#9] CD quality no worse than High Resolution Playback The conclusion is clearly stated. Even the best listener can only have 80% correctness. This tells the fact that people under test are unable to identify the difference. If SACD/DVD is far superior than CD, people should be able to identify the difference easily, average correct rate should be 70 or 80%, and the best listener 100% correct imho. The result of around 50% represents a statistical no difference on sound quality, pretty close to results of tossing a coin. |

[#10] CD quality no worse than High Resolution Playback I think your title should be something like "CD quality no worse than high resolution playback to most of the people". That would be closer to the conclusion of the article. 最後修改時間: 2013-05-30 20:43:38 |

[#11] CD quality no worse than High Resolution Playback 玩開HI-FI既發燒友,耳朵經歷長期聽覺經驗,靈敏度唔多唔少都會比一般人好。除非佢地搵灑所有聽覺正常既發燒友去做依個測試,咁個說服力會大好多。如果連SACD同CD都分不出,基本上佢可以洗少好多錢,聽CD已經夠,更何況LP? 最後修改時間: 2013-05-31 09:58:09 |

[#13] CD quality no worse than High Resolution Playback audio...coffee...wine... taste of mushroom all the same.. nice test.., the result seem to reflect the real life too many people cannot taste the different of a hk$500 wine..to some hiend wine.. many people do not distinglish the different ..if brew within 15 mins of grinding vs.. after3 months...etc.. same case applied..about half of those people feel CD no worst than HRP same fact founding and always a few side of using those data..understand those data.. my family used to think i am chi ma gan.., spending hours for changing the speaker position..., and now they know |

[#16] CD quality no worse than High Resolution Playback not only because..for the proac.. for a few yrs... they come to my room and wait for me.. , and i always force them to learn..haha .. THEY LIKE BIG WILSON and proac... they do not like Avalon, THEY LIKE VINTAGE JBL... and disagree the value of big wilson.., they prefer Krell, but not pass labs... even my mum like vintage JBL..haha... .they WOR..about those Goldmund...and they oooo after they know the cost.. and now.. they do not feel a waste of time..if i make them to sit down for 45 mins for help.., at least they know what i am doing..haha , they now can tell me.. "Good change.." or..oh..a bit less focus..less pin point... and also able to suggest me and tell me the different within 30 cm sitting distance..haha ...not bad good to use them...as they have no brand and price perception however one of the cosine ., a professional pianist.. still feeeling i waste my time for all piano recording.. ,she demo me what are the true dynamic of a piano.... last yr..she had her back up piano in my room... and...oh.... not even 5% capture.. bad even my mum come to help me for cleaning..she comment..this is no better than that..haha 最後修改時間: 2013-05-31 13:35:39 |
