[耳機撚]召集大耳牛、枱式耳機系統用家(31)

隔離耳機po剩係得隨身玩家，hifi po 又主要都係玩speaker , 乜香港地無人玩over-ear, on-ear 耳機咩

吐槽：其實隔離post唔係淨係得隨身玩家，不過隨身玩法洗版太快，好難追到headphone 啲comment
呢度會集中headphone 同埋枱式系統相關（包括DAC, AMP）

Glossary
ASIO
From wiki:

ASIO（Audio stream input output），音頻設備驅動程序的一種。

用ASIO目的係做低延遲，同埋避開OS個volume control
OS個volume control會resample個audio去做volume control，音質會差咗
ASIO要hardware support，唔少要裝driver的 DAC都已經有ASIO support
ASIO4All其實唔算真ASIO

WASAPI
WASAPI係用作避開Windows audio core 個 resampling.
用Exclusive mode(獨佔 mode)之下software可以要求獨佔個audio device (e.g. DAC)，其他program 唔可以同時用同一部dac出聲，而且唔經resampling
所有 program 預設用Shared mode，將唔同program 聲resample 再mix 埋先出dac
傳送audio data個時會有push mode 同 event mode揀

event mode vs push mode
push mode 下program keep住定期問DAC幾時可以收data，等到DAC 答ready 就send data比 DAC。部份DAC有機會因為buffer問題而有decode 問題
Event mode 之下program 準備部份data，等DAC 自己向program 問program data，program先會send data。Latency 會低過push mode。
Event mode 要DAC support先用到。

dBFS
電路訊號強度單位

LKFS
人耳所聽到的loudness level單位，並非電路訊號強度

MMCSS
Multimedia Class Scheduler service (MMCSS) 係windows內有關多媒體CPU schedule服務，對於播放軟件，用高d priority就少d機會同人爭resource
"Pro Audio"為最高priority
foobar 2000同TuneBrowser都可以set MMCSS做"Pro Audio"

Drop.com (前稱 massdrop)
Drop 係一個外國團購網，上面有唔同分類產品，包括服裝、電器、科技產品、Gaiming產品等等。同呢個post最有關就係audiophile分類
URL: https://drop.com/audiophile/drops
IEM, headphone, dac, amp, ear pad/ ear tip都有

平至幾十到過萬港紙產品都有，每個產品都可以留言討論同review；購物區以外亦有forum比用家交流。
（當然，review同討論就好個人，只供參考）

Drop 買野唔ship 香港的話可以用轉運，如buyandship

Drop 運作方式係同廠方合作推團購，有時會用massdrop (or Drop) 冠名同廠方推出Drop 限定特別版產品。好似HD 6XX (即係HD650)

工具
https://www.audiocheck.net/soundtests_headphones.php
呢個 website主要 gen啲tune 出嚟 check frequency response , 左右聲度同左右有冇反相之類
唔只耳機, 試喇叭都會用得
check 有冇左右反相重可以用下面呢條 youtube 片, 佢會話你知幾時段音樂會刻意反咗相:

https://www.headphonesty.com/headphone-power-calculator/
headphone power calculator, 可以用黎計headphone 要幾多watt / 電壓先夠推

電腦播放軟件推介(歡迎提供推介)
。Foobar 2000 (Windows)
。jriver (Windows, Mac, Linux)
免費，多人用，有唔同plugin 及theme
$79.98 US三平台，$59.98 US單平台
多人用，好聲過foobar
。TuneBrowser (Windows)
$1620 yen (約 $130港幣)，平得黎好聲過foobar，有巴打話分析力好過jriver
。jplay (Windows)
€149.00
電腦播歌高級玩法，最複雜setup 要分2部PC，一部做decode，一部做control同storage
jplay本身有player，不過係headless，要用其他software如foobar/ jriver控制

試過幾次都覺得隻味幾濃 食調音多過質素
但係次次都係用平機去推

講緊empyrean

之前係展用唔同amp會聽得出部amp缺點

或者咁諗 其實係一定價位以上嘅耳機嘅質素都普遍好好 可以達到Hi-res水平

中高階耳機質素方面都差距唔會太大 我畀錢就係買佢嘅調音 聲學技術

我食嘅就係味精!!!

咁快又推爆一個post

琴晚個問題未答到就爆post

LM

想試下H800. /H820
去邊到試好
真係想試吓同H6XX 比較 係咪咁大分別
其實主要用iPhone tidal/MOOV usb 去DAC
駛唔駛買high end headphone ?
AAA789 夠唔夠力推H800 ？

你問多次啦

熊仔啦 除非撞正有熟客係到吹水
如果唔係呢間算靜同埋多demo試

AAA789 夠唔夠力推H800 ？

夠

其實主要用iPhone tidal/MOOV usb 去DAC
駛唔駛買high end headphone ?

其實冇問題，我用Stax都有一套機直接駁player，好方便

想試下H800. /H820
去邊到試好

DMA以外都ok
主要係避免夾senn記 amp
就算金聲用Violectric，悶d都好過用senn記 amp

隻聲個質感係幾正 應該鍾意既人會好鍾意
其他人應該聽完就會話係垃圾
問題係好貴 如果同800S差唔多價我諗應該會入返隻

除咗救都費鳩事既HD800/ED10個D
我唔覺佢有特別既夾或唔夾
（音色上可以參考Portable既Pico Slim）

我List下捅過D乜可以會清楚D

我而家手邊會用既
Alessandro MPro e
ATH W3000
Beyer T90
AKG K812
Grado GH2

而家基本上係擺既
AKG K1000 Bass heavy
ATH W1000Z

而家唔係手邊但長用過既
Beyer T1 1st Gen

借過返黎用過一段時間既
ATH ADX5000 6.3 & 4 Pin XLR
ATH W1000

借左兩日咁上下
MySphere 3.1/2

基本上借得到返屋企既話
我會信GS-X唔會殺錯良民既
係鳩既話九成係隻Headphone問題

有冇試過430ha？ 想知同gsx 比較係點

Moon Audio?
大機印象唔算特別好skip左

我最後有考慮過既係Luxman Rudistor同HeadAmp
GS-X當年最大優勢係細部又唔深
如果而家由零重新開始的話有可能會買p-750u算

如果而家由零重新開始的話有可能會買p-750u算

why?

GS-X power supply box個擺位會影響聲
隔得遠好D

我三層音響架用p-750u的話部Stax Amp就唔需要同半部GS-X爭位

聲底上兩部我都受所以純粹係物理上方便程度既問題
