Chi哥,

你 played 果D係乜嘢 files (應該唔係 DSF converted to PCM/WAV 果D)? 高頻有D暗淡。 想問下你D setting 同個 signal path。

道長,

我只是將琴姨姨CD用external DVD drive 駁落部iMac(因它無DVD drive),用VinylStudio rip入 之後set WAV 96/24, save file.

Download 去MacBook Pro,只係用standard iTune播,用條usb 線駁Modi,作 power 及訊號輸出,RCA 出Onkyo Preamp。

冇特別線。

所以play係WAV 96/24.

呢首Kraftwrek “Showroom Dummies”好耐以前用iKey convert 去256kb MP3, 我同様用VinylStudio 轉成WAV 96/24.

Chi哥,

你部 MacBook Pro 睇唔睇到 bit rate?

Mac 比較麻煩。 『Macs can natively support up to 24/96, played through iTunes or other software. However, without a couple settings tweaks, audio files with resolution higher than 16-bit/44.1kHz will automatically be downsampled to that resolution.』

Support XX resolution 唔等如 Play at XX resolution。

MacBook Pro 用 usb digital out 比 Modi 又睇唔到 out D 乜嘢 resolution 比 Modi (Modi 得1粒燈)

Rip CD,我用 EAC,conversion 有好多其他方法。 我未用過 VinylStudio 同 iKey.,所以無意見。

慢慢再研究。

另外一個方法 play 渡口 同 恰似你的溫柔 24/96 files,係把2個24/96 files 入落 Zoom H5 張 sd card, 用 H5 play, line out to Onkyo Pre. 出聲後可以用 iPhone 錄。

Dyna San,

你部 MacBook Pro 睇唔睇到 bit rate?.............Shall check later.

I could see my iMac could output 96/24 with the Dragonfly.

人家講老婆越老越可愛,對音樂電器友嚟講,又好似啱喎。八十年代行中環音響鋪似係星期六節目。如果你”痾肥屎”在中環,當然lunch 日日可以留連煙花之地!
昔日你上金弦同sales 哥哥講,你想要C咩奔達做試音,金弦大部份Sales 哥哥服務一流,試完你轉頭走咗去隔離明發,可能你會買咗對AR 98ls.
有時感覺睇時空,今日如果比你再選擇一次,你會….?

以前見街頭街尾有啲儍佬攞部相機週圍影,原來這簡單之擧,就係回憶喇!如果大家八十年代成日去中環遊電器鋪河,石板街明發可能會係其中一站。
但昔日明發sales 哥哥錢字行頭,所以好多音響友唔多鐘意去!

------------------------------------------------------------------------

Chi哥,

Good,即係你部 iMac 認到個 DragonFly Black, iMac 個 Audio Devices 可以 set 到 96kHz,因為 DragonFly will play music or audio data at sample rates of 44.1kHz, 48kHz, 88.2kHz, or 96kHz。

你部 MacBook Pro 都應該認到 DragonFly Black 同 Modi,2部都應該 set 到 96kHz,因為2部都係最高 support 96kHz。

DragonFly Black 同 Modi 都係用 usb 電。

Bitrate/位元率 係另一樣嘢,流量, bits per second 。 CD 同 rip 出嚟嘅 file WAV 都係恆定/constant bps,1411kbps,bit depths 係 16-bit,sample rate 係 44.1 kHz。

Output 個 16/44 file 去 DragonFly Black,會著綠燈 (DragonFly’s LED displays different colors to indicate status or sample rate of audio data. For DragonFlys Black and Red: Red = Standby; Green = 44.1kHz; Blue = 48kHz; Amber = 88.2kHz; Magenta = 96kHz; Purple = MQA.) , Modi 就顯示唔到。

VinylStudio rip CD 出嚟嘅 24/96 WAV file 唔係真 high resolution file,因為 CD data 只有 16/44/1411kbps,係用 interpolation (mathematical approximations) 方法整容到 24/96 WAV format (4608kbps)。

用 DSD64 file (1-bit/2.8224 MHz,5644.8kbps constant ) convert 出嚟嘅 24/96 WAV file (4608kbps),會係真 high resolution file。

Chi哥 可以比較VinylStudio rip CD 出嚟嘅 24/96 WAV file 同 DSD64 file convert 出嚟嘅 24/96 WAV file。


有 Onkyo pre,Modi (1.5 volts) 同 DragonFly Black (1.2 volts) output 都冇問題。


Mac 用 Audio Devices set 嘢, Windows 用呢個:

Wong兄,我記得,七十年代末行鴨記。當時啲人唔係咁睇重Alnico V. 只要磁石夠大,就算粉磁都話好嘢嚟。
記得當年我也是其中無知一員,我見啲低音後面上咗紅油嘅磁鐵,仲覺得咁鬼細呢,哈哈!

Oh
.. Dyna san

I have a suggestion, if Chi hing can have 2 of the test tracks from you, than future we can have A/B/C test with your files by his zoom concert haha

It could be fun...

By the way. My seem to have knowledge about the preformance of some cheap DAC, wonder any cheap DAC u may recommend?

Haha thx you

Haha

Good Morning/Evening Hong Kong,

對唔住,剛起身,因睇午夜場新Indiana Jones!!!!!

個VinylStudio 都可以save 做DSD file(佢講嘅),但係需要original DSD file, 因我無呢啲file,所以未試過。

先播放一首由MP3 converted (所謂)去WAV96/24我喜愛的哭砂啦。

OK, just been to the garage(my music room) and I felt like inside an oven!!!!!

Today it could be as high as 33*C and I don't think I could do too much in the garage so I quickly check with my MacBook and predicted it recognised the Modi.

However.....stupid me I thought it recognises the Modi and it will change the output to 96/24. As Dyna San suggested it supported but doesn't mean it will play!!!!

I just found out that though my files have been converted to 96/24 and even some 192/24 but it has always been playing on 44.1/16!!!!!

My MacBook can even support up to 192/32 which is even more than my iMac which is just 96/24!!!!

My MacBook is a 2012 model and the iMac is 2017!!!!! Crap!!!!

Some screenshots from my MacBook.

Can't wait for much cooler time later to test it out!!!!
