| [#82] MyTek Stereo 192 DSD DAC Smithkline HING, Thanks for the sharing. A good Power Cord will no doubt improves the performance of the DAC significantly. I am now using Super Cyro PC and will try to connect it with a better one after fully run in to see how big the difference. Happy Listening! |

| [#83] MyTek Stereo 192 DSD DAC 我唔太明白如果開左Upsampling(ON),唔係即係等於Mytek自己reclock去到192kHz咩? 好多DAC都係靠upsampling去杜絕與Transport源頭之間的jitter, 為何Mytek個menu在此設定下還俾用家設定Incoming Sync 44.1呢? 仲有咩意思呢? 反過來講, 係咪應該設定左Upsampling(OFF)而選擇Incoming Sync 44.1或Internal Sync先有意思呢? 各位有冇想過呢個問題呢? 我個人就覺得Upsampling(ON)無疑在分析力上係提升左, 但每次當我OFF返去比較,總覺得唔用upsampling係較自然, 較似原本的聲音; 而我亦試過選擇Incoming Sync 44.1或Internal Sync, 不知為何覺得用Incoming Sync 44.1反而聽落更有層次. 我二手買返黎之後第二日就換左粒fuse, 原本跟機個粒係1A Slow Blow, 有些微粗聲, 換完立即改善了此問題. 另外亦將機內同軸入面至底板同埋底板至RCA Out的cheap cheap電工接綫換了銀綫, 兩極延伸同埋通透感立即提升. 請問現在最新的firmware version係幾多? 唔upgrade住係咪無礙聲音質素呢? 最後修改時間: 2012-02-21 09:53:50 |

| [#85] MyTek Stereo 192 DSD DAC Hi KevinLo, AFAIK, Input Sync means the Mytek DAC will use the clock signal embedded in the AES/SPDIF/Toslink input from the audio playback device. Whereas Internal Sync means the Mytek DAC will ignore the clock signal of the input source but reclock it with its own internal quartz clock. Its a choice of using the input source clock or the DAC's internal clock. For upsampling to 192kHz (for the purpose of jitter removal), it is a digital signal processing (DSP) option. If engaged, it will upsample the signal based on the input source's clock (input sync) or its own clock (internal sync). |

| [#86] MyTek Stereo 192 DSD DAC Reclock不就是將主時鐘時基頻率改動咩? 源頭係44.1kHz, 重新編碼為192kHz時還怎樣依據源頭時鐘呢? 不用靠Internal clock都能Upsampling? 我亦意外地曾經在源頭由一隻CD改播放一隻24/192的DVD-A,當時我setting係選了Upsampling(OFF)同埋Incoming Sync 44.1kHz, 在沒有更改setting的情況下依然正常聽到DVD-A的正常聲音, DAC display當時仍顯示-00 44.1, 如果根據setting主時鐘當時設定為依據源頭時鐘, 我還可聽到正常聲音的話, 那麼我想應該係源頭時鐘因為播DVD-A而轉成192kHz後, Mytek跟隨它所致, 然而DAC setting仍是Incoming Sync 44.1kHz嘛, 實情係Mytek已經自動懂得跟隨源頭轉為192kHz, 我問題係為何Setting內還有什麼需要有由Incoming Sync 44.1至Incoming Sync 192咁多選擇呢? 何需手動選擇呢? 請問1.3.4係最新firmware? http://www.mytekdigital.com/download_library/都係有1.3.2, 請問怎樣檢查DAC內的firmware版本? 最後修改時間: 2012-02-21 16:41:36 |

| [#89] MyTek Stereo 192 DSD DAC Hi KevinLo, I must stress that I am no expert and below is only my understanding which may not be the truth. So those who know it better please correct me if I am wrong. Reclocking means ignoring the embedded clock signal in the input source and instead use the DAC's internal clock or an external word clock as reference. The DAC upsampling process uses buffers and mathematical calculations to step the incoming signal up to a higher sample frequency. In the case of Mytek Stereo 192, its 4x for 48kHz and 2x for 96kHz while 4.35...x for 44.1kHz and 2.17...x for 88.2kHz. Since the upsampling for 44.1/88.2kHz is non-integral upsampling like the 48/96kHz, someone calls this as "asymmetrical 4x upsampling". Since your setting was "Input Sync", that's why the DAC decoded your DVD-A input basing on the embedded 192kHz clock signal. By the way, there is only setting of "Input Sync" but no "Input Sync 44.1" nor "Input Sync 192.0". On the other hand, you could set "Internal 44.1" or "Internal 192.0" as the case may be for input signals of different sampling rates. I think the Mytek DAC can upsample (i.e. apply 2x/2.17...x/4x/4.35...x) by using either (a) its internal clock, (b) the embedded clock signal from input source or (c) an external word clock. 最後修改時間: 2012-02-22 00:24:27 |

| [#90] MyTek Stereo 192 DSD DAC Thank you very much, gluk. 我想我一直無厘頭地倒轉了Internal Sync及Input Sync, DAC個液晶顯示實在幾難辨清,現在睇番就合理好多. 因為我耳仔其實聽出Internal Sync 44.1係比Input Sync好聲. 不過問題仍有三個: 1. 為何setting設定在Internal Sync 44.1/48/.../176.4的情況下播放192kHz的源頭仍有正常聲音,這情形在很多sound cards之下都會出現不正常數碼聲 2. 仍不明白設定為Input Sync及Upsampling(ON)時, DAC在棄用Internal clock下怎樣reclock同upsample? 抑或根本無棄用過? 兩者設定沒有矛盾嗎? 3. 我未玩過Word clock, 請問當利用word clock將Transport同DAC兩時鐘較至同步時, DAC仍可reclock同upsample嗎? 我以為同步的意思唔係應該至少要兩者的取樣頻率s.f.一樣兼同步嗎? 這樣才是jitter free同埋bit perfect的必要條件嗎? 最後修改時間: 2012-02-22 09:31:30 |

| [#92] MyTek Stereo 192 DSD DAC Hi KevinLo, 1) I also tried to use an incorrect internal sync setting that does not correspond to the input source sampling rate. It is indeed strange that the DAC still appeared to continue "decoding properly". 2) I suppose the embedded clock signal from input can also be used by the DAC as the reference (similar to the internal quartz clock or an external word clock) to apply algorithms for upsampling. 3) In a recording studio environment, an external word clock is usually used to sync the ADCs and DACs. For HiFi playback, its use is not as significant. As matter of fact, the interface between the word clock and different devices is also a source of jitter. 4) Apparently there is only "bit perfect" but no "jitter free" playback for all present day systems. 5) You may want to contact Mytek to seek their explanation and clarification of your questions. |

| [#93] MyTek Stereo 192 DSD DAC Having spent the last few days trying to play back DSD directly on the Mytek DAC, I can now report that the results are quite promising. The setup that I'm using is a MBA running 64-bit Win 7 Ultimate. The software player is HQPlayer Desktop 2.7.5.2 (0xAA dCS spec). Since the Mytek USB driver appears to be not very stable for 64-bit Windows, I finally had to put a MF V-link 192 between the MBA and the Mytek DAC. Details of the setup: MBA ＞＞ Oyaide Neo USB ＞＞ MF V-link 192 ＞＞ Cardas AES/EBU ＞＞ Mytek DAC SQ from DSD is definitely superior to 24/88.2 PCM converted from DSD by KORG AudioGate. One obvious reason is that when using KORG AudioGate to convert DSD to PCM,clippings always happen if dynamic range of the recording is high. Would like to know others' experience of direct DSD playback when compared with PCM (24/88.2 and 24/176.4) converted by Weiss Saracon.  |

| [#97] MyTek Stereo 192 DSD DAC tom55, MF V-link 192 serves only as the USB interface between the PC and the DAC. I guess any other USB interface which supports upto 192 kHz could also do it. nanoriver, According to Miska, developer of HQPlayer on Computer Audiophile forum, results of Mytek 1.4.2 firmware & 2.8.0beta5 are: Toslink, coax and AES input - 0xAA and 0x05/0xFA works Firewire WDM/WASAPI - 0xAA and 0x05/0xFA works USB 2.0 WDM/WASAPI - 0xAA and 0x05/0xFA works USB 2.0 ASIO - native DSD works on 32-bit Windows (not on 64-bit) I suppose you are using 32-bit Windows on your Asus Eeepc 900, could you tell me what version of Windows is on your i3 desktop PC? I have not tried foobar2000 with sacd-0.5.0 component. I understand it plays DSD files as well as SACD ISO images. How do you find its performance. Meanwhile when I use HQPlayer on my old Sony Viao NB (Intel Celeron 1.2 GHz CPU), it works fine with 24 bit/192 kHz flac but not with DSD, apparently it does not have enough computing power for that. Could that be the reason why your Asus Eeepc doesn't perform as good as your desktop PC? 最後修改時間: 2012-03-14 18:27:09 |

| [#99] MyTek Stereo 192 DSD DAC Hi kkitkko, 曾福琴行 Hi Gluk, 我估計如果用左有別於音源的頻率黎設定Internal Sync頻率, 係令用家能自由在Upsampling on/off之前設定出不同程度的升頻, 例如播梗CD 44.1kHz, 如設在88.2kHz, 係應會將頻率double, 反而Upsampling On係會將任何sources都加bit升頻至24/192的(根據Manual); 我試過在Upsampling Off時設定Internal Sync 88.2, 播CD時效果一樣很smooth, 但若我改設Internal Sync 48, 則明顯出現些微爛聲, Internal Sync 96都有, 但冇咁明顯, 我想係因為44.1轉48時兩者一來太接近, 二來轉換的factor並非整數導致明顯爛聲. 不過有點搞笑地此估計不知怎樣解釋為何我播24/192 source時, 如設定Internal Sync 44.1-96的話, 都可以有聲, 難道有降頻這回事?? 另外, 我想問我有部Onkyo DV-SP1000 Universal Player, 佢有firewire IEEE1394 audio out, 我記得好似可以在menu設定dsd out, 咁係咪可以播SACD時經firewire駁Mytek由它去解碼玩呢? 係咪應該會好正呢? 最後修改時間: 2012-03-16 09:45:20 |
