| [#22] 最蠢的CAS Hello themouse, Thank you. It seems like more information gather is leading us to your problem. And you are not using a simple system but rather NAS and WiFi connection only. ＞ mac mini與nas是用wifi連接的，有問題嗎？ Wifi connection is okay for CD 16/44.1kHz or even 24/44.1kHz (The Beatles), it will give quite high demand on hi-res such as 24/96 or 24/192. We are not capable to use WiFi to transfer 24/192 playback under iTunes in our own systems. ＞ 如果想重裝itunes，要先uninstall嗎？ No, you don't. But it seems you are not having iTunes problem but your NAS on WIFI is simply not up to the task. Maybe you can try just buy a long ethernet cable, hook it up between your NAS and MacMini for testing. If this setting solves all problems, then it will be your WiFi connection is not fast enough. I have never use Foobar + Windows 7 + WASAPI while using NAS as file storage. But the NAS setup is not capable to transfer 24/192 via Wifi, I will doubt the same case happens on the Windows platform too. We use Mac Time Capsule as our Ethernet music storage. WiFi playback on CD is completely fine. Hi-Res is still not up to the task. But this system replaced the expansive closed system like other companies offerings.

| [#23] 最蠢的CAS 用wifi連接mac與nas，在相同的hardware上，windows是沒有問題的，就算播放24/174.6都暢順，半點窒也沒有，所以唔會係我個wifi connection唔夠快。 在mac的環境下，用nas經wifi連接，播放16/44.1都會窒。我已經將itunes的buffer set到最大，weiss在safe mode 3運作。 如果用mac原來要用lan線連接nas的話，相信這種setup唔符合hifi友的意願，因為多數hifi友都想將發出噪音的硬盤遠離聆聽音樂的地方，唔通要人將個nas拖線去第二間房咩？！ 好似linn ds，都係用wifi連接播放hi-res，一樣暢順冇問題，點解就係mac有問題呢？ 最後修改時間: 2010-02-16 15:51:59 |

| [#24] 最蠢的CAS Hello themouse, Linn DS system uses ethernet wire connection, with special closed system with network routers involved too. There is no Linn DS wireless NAS. The wireless part is only for access control just like you use iPhone app remote on iTunes. I will check with your setting Windows 7 + NAS + Foobar on our system, but you know that different system, program requires different resources and produce different results. If there is a chance you can also check out PC iTunes with the same setting and see if the problem occurs. ＞ 如果用mac原來要用lan線連接nas的話，相信這種setup唔符合hifi友的意願，因為多數hifi友都想將發出噪音的硬盤遠離聆聽音樂的地方，唔通要人將個nas拖線去第二間房咩？！ I do not 100% get what you mean here. Do you mean physical noise of hard disk spinning? I thought these days the harddisk are silent enough. Wifi will not make your system sound better because it uses "no wire" it usually worse in case. If it sounds the same to you than we will be glad that the dejittering of Weiss is pretty up to the task. My suggestion to try on using a ethernet cable can test whenever the WiFi connection is the problem of such case. But I can share that this is not recommended to use Wifi on 24/192, especially when NAS is sharing by more than 1 computer. Bests, Kent 最後修改時間: 2010-02-16 16:31:21 |

| [#25] 最蠢的CAS 噢，原來linn ds唔可以wifi連接nas！ ＂I thought these days the harddisk are silent enough＂ 播放中的硬盤噪音，不是hifi友所能接受的，駁nas之前，我試過用外置硬盤存放音樂檔，但噪音實在太大（我係用LaCie Starck Desktop Hard Drive），噪音不只是轉動聲，還有一種高頻噪音，使人非常煩燥！結果才用wifi連接nas。 ＂Wifi will not make your system sound better＂ 用wifi連接一方面環境會靜一點，另一方面在windows環境下的經驗所知，用wifi連接nas，仍然出到好的聲音（可能如kent所言，這是weiss的功勞，不過之前用chord qbd76，出來的聲音一樣非常優異！） 如果在mac環境下駁nas要用lan線，咁不如簡單用外置硬盤便可以，何需多此一舉呢？！ ＂But I can share that this is not recommended to use Wifi on 24/192, especially when NAS is sharing by more than 1 computer.＂ 都係果句，在windows環境中完全沒有問題！ 我知道elo兄都係有呢個問題，唔知elo兄你用內置硬盤？外置硬盤？lan線駁nas？定係wifi駁nas呢？ |

| [#31] 最蠢的CAS Hello themouse, ＞ 如果在mac環境下駁nas要用lan線，咁不如簡單用外置硬盤便可以，何需多此一舉呢？！ NAS (Network-attached storage) has few benefits. It can been connected via more than one computer at a time without making copies of the files. It can be RAID config. to be more robust setting. For example a simple RAID makes real time backup. It is a very secure way that you do not worry if you will lose any DATA. Your thousand of ripped CDs can be safety stored digitally. If you do not need RAID protection, and you only connect the NAS to 1 computer, you are right that there is no reason to use NAS. A simply external hard disk will be good enough, or just install a 2TB hardisk internally will solve all your problems. And why NAS working with PC but not MAC has a lot of reason rather than it just works or not. ＞ elo兄都係有呢個問題，唔知elo兄你用內置硬盤？外置硬盤？lan線駁nas？定係wifi駁nas呢？ Elo contact us offline and his problem is not related to iTunes but rather between iTunes and Amarra. He is not using Wifi for NAS connection. We have provided an official recommendation that he should switch on the Amarra first and let Amarra switches on the iTunes. Regarding Amarra insync (repeat or skips on iTunes 9.0.3) ---------------------------------------------------------------------- It sounds as though Amarra and iTunes are not communicating properly. This will cause Amarra to loose sync with iTunes, which may be causing the stuttering. So, two suggestions, both related to Amarra's iTunes plug-in...First, please download a new installer. Then, look in your: YourMacBootDisk/Library/iTunes/iTunes Plug-ins folder. In there, you should find a file called "AmarraPlugin.bundle"...If that plug-in is missing or malfunctioning, then Amarra can no longer communicate correctly with iTunes. The Amarra installer should be able to replace that plug-in if it is missing or damaged. Second suggestion: Always launch Amarra, not iTunes, and let Amarra launch and take control of iTunes. If you launch iTunes first, that control cannot take place correctly. ＞ 我都想知道下，用 Windows 7+ Foobar2000 / MediaMonkey，是否真的不及Apple + itune。 Windows 7 with WASAPI is actually better than Mac with iTunes combo in feature wise because the WASAPI output enable the automatically switch sampling rates while Mac cannot. That is exactly why Amarra is ideal. When you want to use MAC computer, and iTunes as Digital Audio Library management, Amarra gives you the ultimate solution. You can still control the music library with Apple iPhone, iPod Touch and soon iPAD wireless. ( all the benefits of using an open system). The Amarra will automatically switch sampling rates according to the native file rate, its output is bit transparent. Regarding audio sound quality in absolute term, I can make a statement that either Mac and PC can sounds as good. There is no reason why one is better than the other. This statement is based on using Weiss as external firewire source. The different is only based on which computer system you would like to use and how to setup your music library. If you want to have a better audio quality system than this, you simply need to buy a better quality DAC. We can provide that in next week or so too. =P If you have problem and would like us solve it for you, we will happy to do so. It is quite simply task to playback CD quality through WiFi connection.

| [#33] 最蠢的CAS Hello Brain, ＞ 一直想CAS, 心中目標mac mini + weiss, 看到此thread, 都是等等最後結果, 再考慮清楚. The rule is quite simple. You cannot use WiFi on NAS and playback HiRes materials with Amarra/iTunes/Mac. This is the same reason why there is no wireless Linn DS. A wire connected NAS is a much more robust system. If you have a laptop and would like to playback CD from the NAS, I am absolutely sure this will not be a problem, even simple Apple airport express works. If you want to have robust system, with all music data backup, and still playback hires. You can store your music on a large external/internal hard disk. And then use Time Capsule for data backup. This ensures your music data is backup while all data is routed from your internal hard disk. The same case applies to when you are using old USB 1.0 connection on external USB hard disk, your max. rate is 24/96 simply because USB 1.0 does not support 24/192 bitrate transfer. We have all kinds of solutions provide to our clients in different level. Contact us offline is preferred. 最後修改時間: 2010-02-17 00:06:33 |

| [#34] 最蠢的CAS "The same case applies to when you are using old USB 1.0 connection on external USB hard disk, your max. rate is 24/96 simply because USB 1.0 does not support 24/192 bitrate transfer." They are not the same case. USB 1.0 Audio standard limit the speed. However, WiFi is much faster and the NAS file sharing protocol would not limit the transmission speed at all. 24/192 is 5.76Mbps only, not a big problem with WiFi. I understand WiFi speed depend on environment. I think Amarra should come with an utility program to test the NAS connection speed to see whether it is sufficient for 24/192 playback. If the wifi is not fast enough, set to lower sampling rate. Or prompt us to move the WiFi station for better reception. It make people look really stupid when we buy Weiss for 24/192 but at the end not able to achieve it at all. Amarra is pretty expensive and I think they need to do better. I would expect it to be trouble free with NAS running 24/192 for the price of Amarra. 最後修改時間: 2010-02-17 00:59:43 |

However, WiFi is much faster and the NAS file sharing protocol would not limit the transmission speed at all. 24/192 is 5.76Mbps only, not a big problem with WiFi. Practically this is another case. USB 2.0 has 480Mb/sec transfer rate however in practical point it almost always work slower than 400M/sec firewire 1394a. In 1999 I have done a live recording research project with AES to have live orchestra recording in Toronto concert hall. The 24 channels 24/96 were transferred via fiber optics from Toronto to LA (West Coast) for live mixing. The stereo/surround mixes were transferred to back to Montreal (Canada, East Coast) for live playback. There were several seconds delay from Live recording to Live playback, but it was a successful project backup by Cisco. However is that practically works even in 11 years later today? It will still requires a lot of care. ＞ I think Amarra should come with an utility program to test the NAS connection speed to see whether it is sufficient for 24/192 playback. Thanks for your suggestion. I agree this will be something that can be done. However please understand that connection speeds varies. I agree it will be good if something like QOS appears to ensure there is enough bandwidth. ＞ It make people look really stupid when we buy Weiss for 24/192 but at the end not able to achieve it at all. Let's make this more straight forward. I do not and will not call Weiss users stupid because Weiss works at 24/192 in all kinds of connections. (AES, SPDIF, FIREWIRE). Moreover, it works under Master Clock Mode while using computer as source. For people who experienced difficult in no matter which level, we will try our best to help solving the case. Amarra is expansive or not depends on which perspective one looks at the case. When there are power cables selling HK$60,000 for 2 meters, Amarra is nothing. When comparing to iTunes, Foobar free applications, it is killing expansive. People can download the software and judge by themselves if one is better to serve what they need. ＞ I would expect it to be trouble free with NAS running 24/192 for the price of Amarra. I hope to clarify this is not the problem of Amarra, or Weiss but the NAS setup is not working or not stable enough for MAC to run 24/192. NAS setup is not a simply system and many variables are included. And while I am writing all these replies on our Quad G5, we have been listening to 24/192 files with Amarra/Weiss. The music data is stored on our PC server and network connected to our G5 workstataion. 最後修改時間: 2010-02-17 01:34:19 |

| [#36] 最蠢的CAS My original setup was using NAS (Lan not WiFi). All files including hires played without any problem. Then I changed to external HDD with USB connection. At the same time I udgraded to iTunes 9.0.3. Then the skipping/repeating problem happen. So I am still puzzling whether because of my change of setup or because of the iTunes 9.0.3. I may need to spend some time to figure out and solve the problem. So at the moment I cannot pinpoint which part to be blame. Anyway Kent is very helpful and I think he response to this matter professionally. 最後修改時間: 2010-02-17 01:51:26 |

Just out of interest, when you are saying that foobar is a bit better comparing to itune (without Amarra), are you using the same computer system? In other words, did you install foobar and Windows 7 (via bootcamp) in the very same Mac Mini where itune is installed under OSX? Or the test was conducted in two different hardware (e.g. a Mac Mini and a Windows-based laptop) |
