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)

快快地聽,慢慢地說,慢慢地動怒
reply之前唔好心急,review一下就會避到唔少爭執
一去到意氣之爭就好難將你想表達論點令人聽得入耳

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:

headphone power calculator, 可以用黎計headphone 要幾多watt / 電壓先夠推

睇完ppt 介紹Fm編文真係好勁

Chi-fi 俾人睇唔起終究就係大陸人做野太求其
睇得多有線中國組都知大陸人做野有幾隨便
成個社會由上到下都係求交貨就算
所以機器貼片嘅dap, amp 還好,去到要依賴技術員手工嘅揚聲器大陸真係無乜邊家比得上歐美日。膽機又係, 大陸無靚膽機因為無人識翹靚牛所以大陸係無hi-end 膽機。做野求其,又點會有創新能力,所以chi fi 產品永遠就係將外國現成方案用更低價格做出黎黎提高cp 值。 抄1萬蚊嘅機,抄出7000蚊嘅質素,然後賣5000

其實大陸都有好好嘅技術人員,知道咩係靚hifi 又識做靚hifi, 但係呢啲人種停留喺自己出黎單幹做小作坊嘅level, hfman都算係少數有winney 做研發調音+個識商業化嘅米飯先有依家嘅成功。依家winny 走左hfman 最靚嘅果兩隻耳機都係換殼版he6同換殼版Jade

大家點睇denon D9200,上網見評價幾高,但係呢度好似冇乜人買/講咁
2021-02-25 10:19:32
fm 掌舵人係科學發燒之餘仲將元件選料玩到極致
hifi 做得好要夾機,夾料但係依家大多數產品啲人覺得好唔好就係喺度數幾多乜乜物物並聯,水塘幾大,機入面幾多粒wima 電容,功率幾多,尤其係新產品發佈未有實物時。用咁樣方法去估一部機實力咁堆料chi fi 當然有優勢。如果比我我都會係咁因為如果有個牌子同你講佢部雞料amp 其實係經過精密設計咁自然堆料更有說服力,畢竟hifi 界呃人野太多
