你真的去聽過並去比較過你說的這些撥放器嗎?
ZX1和iPT5、F886、iPhone 5S有去一台一台聽過嗎？
以上四台我都有但實際接上耳機聽到的感受和你說的卻不相同
每台撥放器都有它擅長的地方
iPT5和iPhone 5S的聲音我也喜歡但就是推不出ZX1能推出的空間感和細節
「別只用你的感覺批評任何器材」？？？
看你的文章内容和回文我不知道你説這句話是否恰當
我只能說大家都非常仁慈

數字的確足以當指標參考, 並不代表一切
聽感也同理, 只不過要自行忽略常見的神化/無敵論的用詞
但要再扯到那家最會洗腦, 則是另一回事

我不光講隨身聽這塊, 還是你挑特定產品討論
iPod/EarPods:
"And the audio quality is so superior, they rival high-end headphones."
沒看過音質相關詞?
ZX1那兩張能解釋什麼?
又不是兩家的內部都有這樣的原件, 卻只有Sony拿來作文章
更何況apple只一直告訴顧客它的東西有多好, 曾公佈用料細節嗎?
若只針對所謂的Sony粉, 那是否有聽過果粉?
更別提有些沒買卻一直幫店家宣傳的, 變相成商店和代理商開始搞這招, 這才算洗腦
iPhone沒用過, 但iPod classic這以播放為主的可是有底噪, 也該批一批?
會認為, 難道不會爬文看看往例?

我說隨身聽，是因為我這篇在講隨身聽。要扯earpods也可以，你有看到大家把自己的耳機都換成earpods？所以這不是洗腦。
zx1那兩張圖，你可以數數看"高音質"這個詞出現幾次，明明連iphone都贏不了，還主打高音質賣你兩萬塊，你說噁不噁心。
再來談ipod classic底噪。你若認為ipod classic的底噪該批，那你更該批sony zx1,因為zx1的底噪比classic大了1.7分貝。
-------------------------------------
我整篇沒提到我的聽感，因為聽感這種東西太好反駁了。一句我聽起來不是這樣，哪怕打一堆聽感都可以被否定掉。

iPhone功率低，所以他的放大器不會把你的Sine波的頂跟底切掉
大型器材的功率高，所以有可能他的放大器會把Sine波的最頂跟底切掉一點點，所以THD才會上升
我之前有用過TSMC的高壓MOS庫, 有些MOS的閘極可以給至少20V
應該要從總體的數據上看才對, 無法從單一的數計來看
很多時候都有Design Trade-Off, 從一個攜帶型跟一個大型器材, 這兩個設計方向是不一樣的
所以你這樣比其實不公平
如果你對音響設備的數據or設計有興趣 可以看:http://nwavguy.blogspot.com/
我本身不是專門設計音響設備, 所以看他的文章會比較準
他有一個文章就是講Nuforce uDAC-2
因為他nwavguy發表的數據對Nuforce是不利的,
這是其中一位Nuforce工程師的回文:
“Your uDAC-2 is within spec, and both of our measurements are correct, just that we are looking at different part of the plot. If you are going to publish your report, I appreciate that you also publish our response, which you will find that we did not dispute your finding, but it makes a compelling case why we TUNED uDAC-2 this way.”
NuFORCE’s RESPONSE: Jason Lim from NuForce responded to the Stereophile Measurements by saying NuForce believed the performance was “addressed by the design”, they made “decisions based on listening”, and “the measurement was a surprise to us” because it seems they never measured the jitter, or likely the noise modulation, themselves.
他們是靠聽覺來設計他們的產品...
nwavguy舉辦過一次盲聽:
NuForce uDAC-2 ($129) - This is a popular second generation USB DAC from a company that specializes in mainly DACs. It sits above the $99 uDAC2-hp in their product line. It has line, headphone and digital outputs and uses a 24 bit/96 Khz chip. Here’s my detailed review.
Behringer UCA202 ($29) – This inexpensive product is the lowest priced USB DAC from Behringer--a pro audio company that makes hundreds of products but only a few DACs. It has line, headphone, and digital outputs and uses a 16/48 chip. Here’s the full review.
Benchmark DAC1 Pre ($1595) – This is an award winning, very well reviewed USB DAC/Preamp with excellent measurements. It has line and headphone outputs and uses 24/192 chips. The Benchmark is included mainly as a reference to help establish any “sound” the Benchmark ADC1 doing the recording might have. It represents a product well past the “point of diminishing returns”.
以下是結果:
Total Benchmark Line Out 12
Total Benchmark Headphone Out 9
Total NuForce Line Out 8
Total Behringer Line Out 4
Total Modified Behringer Headphone Out 5
Total Behringer Headphone Out 3
Total NuForce Headphone Out CX300 1
Total NuForce Headphone Out Ultimate Ears SF5 -4
