每部機都要外置電, 先夠有型

間屋熱L到好似暖爐咁

LPS唔會太熱啫.

可能我部 Aurender S10 較舊，RAM 唔太夠用。另外我每個組合都會連續試幾隻歌先轉，所以也可能因為咁所以 ...

其實加左Audio Switch主要有咩改善左？

從科學角度用了 audio grade switch 在聽感上有進步是解釋不通的。但是有無數 audiophiles 都會贊同加了之後有明顯改善。對我來說最簡單的就是耳聽為實。我現時手上也有差不多10台不同的 audio switch，經過多番的試驗我絕對相信它是一樣在玩串流中不可缺少的設備。

信不信由你，加了四個 switch 後我現在串流聽Tidal 還比聽檔案好聲。檔案是儲存在 Aurender  的硬盤內，理論上在聽之前檔案已轉送到 RAM 內，所以靜止的硬盤不用操作亦不會產生任何噪音，影響音色。反過來串流方面當然是需要用外置的 lan 線把數據傳送到 Aurender 才能播放。理論上檔案必然比串流好聲，但用了超級 switch 組合後效果截然不同。

師兄, 想順便請教一下, 如果本身已經用緊 AUDIO SWITCH,  咁其實仲使唔使再加埋 AUDIO ROUTER (e.g. OCXO router)? 有沒有明顯效果？ 謝謝。

actually, i studied long time on CAS.... and almost one of the first one in HK to buy all the different switch to test out and study switch in relationship to CAS replay.
From my research about CAS, what make CAS always lose to CD and LP is because of Jitter....
So i spent about this five years to prove CAS can win CD, and even LP. at least CD replay..
i think i did a very good job in proving that CAS can easy win CD and LP.......
i showed a lot of Ching about this finding.

and one of the key element is Switch..., so i spent long time to study and DIY switch with Edison, from Ediscreation. before he built his first amazing switch.
A lot of R&Ds in network connection as well.... hahaha{:5_475:}

To cut it short, Switch is like a center brain to received all different language/ rates from different gears and "noise", like router, your ipad control etc.  consistent them all into one language and output to DAC. so this will reduced the workload of DAC to translate them. reduce the jitter in big time. So Accurate Clock will play a very important role in reducing the jitter. the more accurate it is, the more analog it will be.

I used three switches, all served their unique purpose to reduce jitter.
Network internal wifi system, Audio streaming router, Nas etc...  and LPS and a very clean power source.
CAS is very sensitive to all little little thing. Don't need to invest a lot of money relatively but need to invest a lot of heart.{:5_481:}

I totally agree with ching's assessment.  I have also tried different streamers and personally I find investing in a combination of good audio switches will produce a more remarkable sound than spending the same money in upgrading to a more premium streamer.  This, of course, is assuming one is already using a decent streamer to start off with.

To share a bit more on my experience, my original streaming (with 3 switches) already results in better sound than my T+A CD player used as a transport to send digital signals to my Nagra DAC.  At the time, I wasn't able to distinguish much difference between playing files vs. streaming Tidal.

And now with 4 switches, streaming Tidal is able to beat playing the internal files hands down.  This is truly amazing!

Dear kahw

"I used three switches, all served their unique purpose to reduce jitter."

Can you explain further your rationale, what kind of switch to deal with what problems in the system?

Many Thanks

you experienced  the magic...
Tidal is very very good actually.
but files is always better. it is all depend how you rip your CD. i ABCD tested with a lot of ripper and rip method.
Files is always marginally win tidal. and i found ripped files win HD files most of the time... more musical.
Ethernet cable is another factor actually in CAS... {:5_538:}

Don't call me Crazy...

I have one cheaper Swtich OXOC to control the jitter of my home netgear wifi6 mesh.

2. Ediscreation switch to further clean up the noise from home router before feed into my hifi router, which my tablet connected. To eliminate my home wifi interfaced with my Hifi network. when this config. i can turn off the internet for hifi when i am not listening to tidal.

Above is turn on only when you listened to Tidal.
Below is another another set of Router + Switch combo.

3. Mod Router feed into a heavy modified Buffalo Switch. Then buffalo Switch connected to Modified with OXOC Sotm using optical cable. using Optical cable to further reduce the noise.

4. Sotm connect my DAC and Nas.

Using this way. i reduced the jitter step by step.
Hopefully i can explain this well. Please feel to tell me if you need more info.

Relax

Did you compare the same Tidal files - downloaded Tidal files stored in the S10 data disk vs streaming the same Tidal files? I do not know about other players, but in S10, all will be copied to the system disk before playing regardless of if you are playing internal file from the data disk or from streaming.   If you dare to take out the system disk, you will be able to see a lot of things there.  I am not suggesting you to do it because if the system disk 打柴, the online support will not be able to help you, you will need to send back to the agent for repair.  I do admire you to spend so much effort and $ on the networking side to improve the SQ of the (relative old) S10.  Since you find the audio grade switches has really made good improvement of your S10,  have you tried to put other (newer) players in the S10 spot and compare?

Logically I would think the same thing, that files sound better and more musical than Tidal streaming.  Well, I'm sure the files I was listening to were not ripped the most professional way and that was probably why my Tidal streaming performance had produced more pleasing sound quality.

Anyhow, the fact that I am now very happy with my Tidal performance is great news.  As most albums released are readily available on Tidal I can heavily rely on streaming going forward.  I may still want to buy some hifi CD's from time to time but the convenience of streaming is amazing.

I am not sure if Tidal streaming will actually be first copied onto the S10's RAM.  However, I know that you cannot store the Tidal songs on the S10 hard disk.  I always thought that the only option for listening to Tidal on S10, or other Aurender units, is direct streaming.  But I could be wrong here...

In terms of trying out other streamers, I have listened to quite a few in the past, including Lumin, Sforzato, Auralic and other Aurenders.  The best I have used, apart from the S10 I am currently using now, is the Amare Musica Diamond Music Server.  It is comparable to my S10 and I'm still keeping it in my office.

I have fallen in love with the Aurender Conductor app and I prefer using it over Lumin, mConnect, etc. which I have tried over the years.  I have to declare though, that I had never tried Roon.  I think I prefer to stick to the Aurender brand as it is simple to use and the system requires least processing power.  That is one of the reasons why S10's performance is on par with N20, and is probably one of the best valued streamers available, IMHO.  I have discussed with Aurender US's technical staff extensively and also Vigor Audio HK in terms of upgrading to a later model, and the conclusion is that unless I go up to W20SE or N30 there wouldn't be distinguishable difference in sound quality.  I have also tested the N20, unfortunately in a different setting and not in my home, and what I heard was far inferior to what my own system is currently offering me.

So the short answer is no, I have no desire to upgrade, at least at this moment, as I am rather happy with the overall performance of my old S10 combined with my Nagra DAC.

Think you can buy and download Tidal songs to the S10 data drive, then you can do a proper compare with streaming.

Thank you kahw for your reply.

Do you mean,

On system 1:

Netgear wifi6 > OCXO switch > Ediscreation > Hi FI

On system 2:

Mod Router > Buffalo > optical > OCXO Sotm > DAC and NAS

Thanks again

我沒有玩 Spotify，主要原因係 Aurender 不 support。如果聽廣東歌，個人認為不需要高質素的 hifi，因為錄音已經一般般，我倒不如聽藍牙喇叭，相對方便。
