your so called limited and not so update knowledge , already having so much info for me to start

i do have choices... either having some sort of mesh wifi network to my playroom or hard wire CAT 6 cable network

i shall look into that Plex and HQplayer over the weeekend

thx thx thx

Indeed, for playing digital music , there are some ideas:

- gigabit network wired connection for streaming HiRes music
- get rid of wireless network connection among components because variable network transmission latency causing poor sound performance (variable data packet transmission intervals exist regardless what WiFi speed being used)
- play local music files always performs much better than streaming from internet currently
- if using USB DAC, the length of USB cable should be less than 1 meter, which is the industrial USB standard for ensuring error-free data transmission via USB.
- I don't believe those network components priced thousands dollars with HiFi terms. Just using qualified industrial standard products are error proof enough for data transmission
- Computing technology do have error checking/rectification protocol and mechanism in data transmission to ensure the received data files are exactly the same without bit error. There are DACs USB driver input allowed to adjust the buffer/cache to have received the audio file fully before starting decoding/modulation. This assures error free music data file recieved and minimized any data transmission issues caused by up-stream streaming application and network connection, and thus less performance influence caused by whatever steaming application used. This requires the DAC's own specific USB driver to configure i it appropriately. Whether you like the sound then only depends on the oversampling/filter/modulation and analog output from the DAC itself, but not from where/what application it send the music file. Though this real time audio streaming technical protocol is still not advanced enough to fully achieve perfect USB Audio streaming for best sound performance yet.... because the small HiFi market segment is never the digital music market focus.

For me, playing LP is an art for music reproduction. May be one day I'll come back to play vinyl again :)

Basically, 以我所知, Windows still provides the most capable and flexible HiRes sample rate for audio input and output interface, second by Linux, and then Mac OS. 雖然 Windows 本身一路都被批評有太多 built-in over-head process 會影響音質，但以而家嘅 latest super processing power 黎講，呢啲基本上已經 negligible, 但當然，有啲基本 Windows settings fine tuning 仍然可以做去 optimize application performance. 加上 Windows 嘅 user friendly interface, 基本上家用嘅都已經好輕易 setup 同非常唔錯效果。

Linux 相對大部份用家未必熟悉如何自己 setup, 且絕大部份 DAC 廠家都唔會特別為 Linux platform customize DAC driver, 故 can only use standard Linux built-in USB Audio drivers for most DAC, 未必能 fully utilize 部 DAC 嘅feature 同 performance，如 native DSD256/DSD512；但因開源免費，基本上現時所有廠製 Streamer 都係用 Linux 底裝 streaming application, 普遍用 volumio。

Mac 有用家話比 Windows 好聲 (其實 Mac user 甚少會用番 Windows)，但 Mac OS sample rate 同播 native DSD stream 有 limitation, 在我而家擁有 both high sample rate HiRes file of PCM and DSD 黎講，並唔係首選。

在小弟現用 Windows 10 上，常用 Plex Media Player (PCM) 同 HQPlayer (DSD upsample) 播歌，試用過 foobar, jriver, audiorvana, library or sound performance or DSD support 總未如理想，權衡音質，features, 易 management and user-friendly, 及 DSD support 度, 暫時以 Plex 及 HQPlayer 已能滿足小弟現時要求。但玩 application 要留意 version changes 對音質影響，如發燒友覺得 Plex 音質一般，其實 Plex 舊 version 音質較好，尤以 Plex Media Player 最後幾個 version 最好。如單以音質計，我會推介 HQPlayer, 尤以 DSD256/DSD512 upsample 計。

以上皆 according to my limited and not quite updated knowledge, 有錯請指正。

To me, the LP sounds better as compare to digital sounds, you got a fuller/solid body of the singer.


有肉地啲, same issue as film/digital pictures.

At this moment...

I am using foobar or squeezbox, files from a workstation notebook. And USB cable to either a topping d50s, or a China DAC with a 9038 chip

以上所有嘅配搭 冇覺得難聽, do feel the foobar may sound nicer, may be the squeezbox do not have the adequate plug in yet
My standard 1.5 meter molex usb cable seem better Than my diy USB 3.5.meters cable..., however.. 兩條線都冇覺得難聽


My old meridian 800 cd playing seem 好聽好多嘅, however 可能就係使用感及心理作用

尤其是缺乏control for comparison.. 所以任何嘢都不能作準, 最重要係

1) 完全冇覺得難聽 after setting up the foobar with some plug in

2) 好似有可以有好多嘅進步空間 ( 如果有日發燒起都幾好玩)

Especially the topping and China DAC 我都係幾百蚊港紙二手買返嚟嘅

我完全唔信自己喺唔同setting之下有認知地嘅比較... Haha

都研究咗過幾兩個禮拜.. 先至搞到覺得唔難聽

I can spend 20 mins to set up a table with a cheap MM.... 就覺得幾好聽


But so many interesting music out there which I will not buy LP for. Those music...


Better learn more from experience users...


Haha

可能又係心理作用

More from my cheap SACD/CD/Network Player.

Also, as I mentioned about Liz Story earlier for reference.

My cheap cheap cheap streaming setup

Wi-Fi to iPad Pro, Tidal Hifi Plus account, unknown USB C - USB-B cable to SMSL DO300, XLR to Burmester Rondo integrated, to clone 3/5A

I’d quit digital music since I bought my LP12 in the Millennium, my last DAC was a Wadia 12 which has the strongest character I’d ever came across.

I can only say the digital music reproduction goes a long way since then, the SMSL DO300 performance is almost top tier DAC in my dates with only a fraction of the cost, and a PRC made. You could never imagine.

Check this out, these guys are advance class in digital music streaming.

That is useful sharing


Which software player u used and use now?


I have started to collect files haha, and within a group.. We start to exchange files too haha

Any reason for. Using micro PC, but not a powerful pc or Mac?

We may not be expert onamy things, but experience does count haha

Thx Thx, when u have time.. Tell more

From those sharing, knowing that, u are a critical listener, and this is a sport and experience is a great deal... I have not. Listen to any hifi set up critically for 10 yrs.. So I am rusty haha

Haha

Haha 兄，love sharing as always. 利申：I'm no expert of digital playback neither. :)

小弟現用 micro PC 和 Windows 10, 裝 playback software 同 ASIO driver, USB cable 出 T+A DAC 8 DSD，XLR cable 去 Vitus amp. Just that simple. 一路以黎，我 mainly 剩係播 music files from local NAS, gigabit wired network, 如我一路觀點同體驗，audio performance of internet music streaming is no comparison to local file playback. 所以小弟並無花錢 subscribe Tidal, Qobuz 等等 HiRes services。

小弟反而因為本身係 Amazon Prime member, 因利成便順便特價 subscribe 咗 Amazon Music HiRes 試試, 其實 causal listening 着實音效都不錯，雖然自己甚少開黎聽，但因為佢個 music library 實在非常龎大，基本上要聽嘅任何音樂都差唔多一定揾到咁濟，有時會用佢播啲新野或另類野聽吓，啱聽先至買 HiRes files download 落自己系統正式聽，反而我個女用咗我個 Amazon Music account 喺佢自己手機，create Playlist 聽佢鍾意嘅歌。。。 haha :P

Yoyoyo good morning spring

Wonder how's u play thsoe ditigal music? Tidal etc

I am learner for digital playback, happy to share a little bit about your digital chain, and what u had and what u prefer etc?



Thx Thx


Haha

There was always and there is always some extra effort for those young fellows who under achieve.. Teacher volunteers to offer them more assistance after school hours as a small workshop or even one to one at library.... Delighting things


I also notice there are competitive type of paid tutorials around many places.. My first feeling is.. Omg..

As I am a believer for passion driven learning, if someone want tthat piece of knowledge so much, they will learn by their own initiative, hope those services are given for those young and early passions

What the point to spend more hours for those advance math at 13..15..if they do not even want to solve or understand a real physical world on how's things
work? Or why.. Etc..

2 hours a week.. 35 weeks a year .. And 3 yrs..

Not lazy is always nice


I met a young lady at 17, my buddy daughter last month.. She seem streeful from hard driven parenthood..I listen I offered some prospective on how passion work and how honesty works, good luck on her

Wish her be brave to make a changes and find her passion, and not wasting too much time on things she could not like



I was amazed by some of the mature students I met in the past..
What had happened had happened.. However tomorrow and later today, we can always make. Some. Changes... Haha


My side is not sunny today... But peaceful

After class lesson is common for sure but normally for those low grade achievers or at the other end of the spectrum, the extremely competitive high flyers. That said if the intensity and expectation from both the school and parents as complex as in HK?

I sincerely hope not.

老友想知
有幾十支舊洋酒攞過去有冇特別手續？
Thx

其實係uk 都好多人補習
私校一向都有要額外比錢after class lesson
另外India 都勁多人補習
唔係淨係香港去的小朋友

#1362

朵 tulip 真係好大！！ ＞o＜

#1360

Tuition is becoming quite common in UK now, I afraid.... 好多香港家長黎到都係第一時間揾補習俾仔女，不論小學中學，而家亦有不少 local 都有 join；我仔女啲學校，將 GCSE 定性為極其重要影響
將來前途嘅 examination... 我阿女小學 yr6, 而家中學 yr7, 學校都已經係話為佢哋預備緊 GCSE。。。 OMG....

Haha 大過我個拳頭
