完全同意的 - #52 [唐吉訶德], 18-07-11 21:51Lossless?
我完全無法想像 Tidal file 的來源 -
- #51 [長長影子], 18-07-11 20:12其實如要 verify 一個 format 或 codec 係咪真係 lossless,只需要客觀地量測及比較 signal chain 之前嘅訊號同之後比較有幾接近,唔同嘅地方喺邊度, signal A > a/d > data A > data B > d/a > signal B
既然 MQA 嘅理念係在於修正器材 a/d d/c 等等偏差,一般傳統所謂嘅 lossless format 只係睇 data A 係咪等如 data B 其實係冇意義嘅,因為真正 lossless 嘅意義係需要比較 signal A 同 signal B 之間嘅差異,而唔係只局限於比較 data A 與 data B 之間嘅差異。 - #50 [MLfans], 18-07-11 18:51Please have a read of this article from Stereophile. I am 100% with Jon Iverson!

I am very happy to see that we have a lot of exchange of information and opinions on MQA. I respect all chings comments if they are based on solid facts and not self-opinions, "concepts" or "philosophy".
Time will tell whether MQA will become a widely accepted format or just a hype that will die in a few years time.
Happy listening :)
Disclaimer:- My experience with MQA is through my Lumin A1 playing MQA files from Tidal. I am a music lover and not working in the audio industry so have no personal gain or loss whether MQA is going to be successful or not. - #49 [長長影子], 18-07-11 12:19多謝分享,重點講解得非常之清楚。

- #47 [wklie], 18-07-10 16:55There are 10000+ MQA albums on Tidal. To see a list of albums check this out:
https://www.meridianunplugged.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=268318
The best way to try out MQA is via the 60-day free trial of Tidal HiFi:
http://tidal.com/masters
(Tidal MQA is delivered in 24-bit. MQA CD is delivered in 16-bit (before any decoding) only. The former is better.)
It costs HK$96 per month for lossless 16/44.1 CD-quality streaming, and no additional cost for MQA streaming. Note that to sign up for Tidal one should use a web browser, instead of Tidal app on smartphone, since the latter will charge more than the regular price by Apple or Google.
To perform first unfold of MQA (Core decode) to 88.2kHz or 96kHz, you can use the (free) Tidal desktop app for computer, Audirvana, or Roon 1.5. For full decode to highest sample rate you need a MQA certified player such as Lumin product line, Esoteric N-01 / N-05 or TEAC NT-505.
For those who prefer Hi-Res streaming instead of MQA streaming, there is Qobuz. You need to create a Qobuz account by VPN to UK or France. Actual streaming does not require VPN, but Hutchison internet services may not stream consistently well enough in my previous testing, with HKBN being a little better and PCCW probably the best for Qobuz streaming.
https://www.qobuz.com/gb-en/plans/music-streaming-subscription
Qobuz pricing is EUR19.99 per month for 16/44.1 lossless CD streaming, or EUR349.99 per year for Hi-Res streaming, with Hi-Res defined as anything between 24/44.1 to 24/192. Some Hi-Res albums cannot be streamed even if they show up in the catalog, they are for your purchase only.
Lumin product line, Esoteric N-01 / N-05, TEAC NT-505 also natively support Qobuz Hi-Res as well.

冇錯, 各師各法 ! - #44 [長長影子], 18-07-10 11:13音響技術層面廣闊,有眾多不同嘅專業領域,應用層面及研發層面各有唔同專精嘅地方,河水不犯井水,亦無必要去比較又無高低之分,但相信技術上可以互相學習交流嘅地方有好多,不過無需要畀人借故煽風點火。
- #43 [唐吉訶德], 18-07-10 11:00#41
太多了吧
Grimm, D&D,Genelec.............. - #42 [阿鐵], 18-07-10 10:34Kent Poon怎可能跟長長影子比較,研發層面與應用層面分別。
- #41 [kx14cp1], 18-07-10 10:12那根據 #24 長長影子師兄所講,有咩喇叭重播聲音的分析力還原度較好?如軟件ok,但到喇叭輸出時限制了,前段攪幾多都無用。
- #40 [長長影子], 18-07-10 00:23我唔識 Kent Poon 本人,我亦相信佢都唔會識我,不過我估 Kent Poon 大概係偏向 audio 錄音技術應用,而我係偏向電聲技術研發。
- #39 [長長影子], 18-07-10 00:11另外順帶一提,唔好以為送得越多 data 就一定越接近原音,所謂物極必反,冇意思嘅 data 及運算亦有機會為 DAC 帶來更多 noise 以及電源干擾等等,DSD 本身附帶嘅 noise 都一樣會影響音質,亦有唔少 DAC spec 都有標示越高 fs 或 clk rate,THD+N 亦隨之而增加。
