CKKeung 兄，
C1上「Ethernet Streaming 輸入勝過十萬CD Transport」 的問題，要等SimCity兄set up ethernet streaming 以後，麻煩您再作一次家訪分享了。

simcity兄 seems to have not much interest in further improving his NAS.  He has already been very satisfacted with CD & LP playback.


There is in fact much ground for improvement :

• QNAP NAS vs the new Buffalo LS421D NAS which claims to be particularly DSD-friendly.
• Choices of playback softwares : Twonky vs MinimServer.
• Choices of HDs or SSD used inside the NAS.
• Linear powersupply for NAS.
• Linear powersupplies for router & modem.
• Different kinds of LANS cables.
  

Nickif hing : Please go ahead to tweak yours and give us a progress report!

CKK 兄，
CH used the Synology & QNAP NAS server + Minimserver for DSD native files (DSF and DFF types) in house testing.
As there is a  PC/Linux version Minimserver, it is worthwhile to try to use the a PC as a uPnP server to reduce the workload from NAS.
The path is necessary to be take care particular the section from router to C1 .

k500a hing,

Yes, Synology & QNAP NASs + Minimserver have all along been the proven combos for CH.

However, Florain Clossy of CH emailed simcity hing and asked him to try the new Baffalo LS421D NAS which is formally announced as one of the best choices for CH C1 ethernet mode in Japan.

Here is the news/reviews of D421D in Japan: http://www.phileweb.com/review/article/201312/16/1009.html
LS421D gave better sonic performance than the Baffalo LS-WV/R1J NAS although CH C1 was not used for the shootout.

Thanks a lot for your update.
Looking forward to getting news from nickf about his setup.

I don't have the money to have C1, but Minimserver is a must-have for streaming from NAS/computer. I installed Minimserver during the Xmas break on my Synology DS412+ and never look back. Miles better than the Twonky-based stock media server of Synology in terms of sound quality.

There is a detailed installation guide for installing Minimserver onto various OS in the Minimserver webpage. It would take less than 15 minutes even for computer-handicapped to successfully install.

I have done everything in your list, plus investment in vibration control for the NAS chassis. The only thing I haven't done is using SSD, for cost, storage space and concerns on noises created by SSD. I am using enterprise grade HDD, which generates minimal motor noise. Actually the noise from the fan of the LPS for my NAS is a lot louder and annoying. That said, I have the NAS in another room so not close to the listening environment. So it doesn't really matter, in terms of the physical fan noise.  

This is actually the checklist for the NAS streaming route.

kahw

I am using Lumin with LPS, Qnap NAS with minimserver and Apple Route with  same LPS.
Yes! the LPS for NAS is very Noisy.
JPS in Wall to LPS for NAS and Router
T-Alder alexandra for Lumin.

AQ Diamond CAT 7+ Acoustic Revive Silenter from NAS to Router. Acoustic Revive to Lumin. i have tried with two AQ diamond. No Good! too Bright.

Two paths to Pre amp
1. a DIY silver furutech BNC to RCA head, by Ben cfu, digital out to goldmund 20M DAC. The only problem i have is goldmund take only 24/96. but it is really good to me. No loss to CD, if using HD track. Not rip version.
2. RCA, AFA gold cable to Preamp. A little lesser than 20M interm of "Smoke". but it is really good as well to me.

I really think i did a good job so far, Always double check with CD and LP to make sure it is close enough.

Dea Diamondback and Kahw,

Many thanks for your sharing.
So you are experienced 老手/vaterans in NAS!
Nickif shall learn from you.


Minimserver is the current standard in CAS with NAS.
But if Florain Cossy of CH recommends Baffalo LS421D, there must be a reason!

I heard that LS421D has been tuned by the Baffalo staff specifically for music playback!  

Maybe some highhands can compare it with Synology/QNAP and compare Minimserver/Twonky in Baffalo and tell us the result!

ching,
IMHO, running music playback service on NAS is not a good idea, because the CPU has to deal with lot of jobs in NAS. I think doing this has the following advantage:
1. Cost (cheaper than setup another PC for music playback)
2. Space saving (only one box instead of two)
3. Shorter setup and learning time
4. More eco-friendly (point 1+2+3)

I never have serious AB comparison to proof what I said above, as I have extra hardware and space for a dedicate machine. I don't know the reason why you don't want to setup a PC for music playback but if you have some spare PC, why don't give it a try?

Interesting suggestion.  haha  

But I believe in the integrity of Florian Cossy & Thierry Hebb.
I don't think Florian suggests Baffalo because he has received money from Baffalo.

Welcome to CH family.

Thanks Kahw ching, scratching my head trying to set up the NAS here...I suggest all NAS products put such language on their manual " Warning: you may need a PhD degree to set up the NAS successfully!"

Hi Obee hing,

I had my current streaming plan sketched back in 2012 when I planned for a major home redecoration, and NAS was the core (when there were less products and discussions re CAS as of now) that's why, and still is the core of the plan . My experience with NAS could be dated back to 2006 when I went serious with playing back from computer for the first time, using MBP, a RWA desktop battery-powered headphone amp and Benchmark DAC USB at home and iPod while on the go.

The most important thing about NAS for me is storage size. When I started with more than 3,000 pieces of CDs and the size of uncompressed 24-96/192 wav files I can't really stand to use one PC for storage and music listening at the same time, unless I load what I would like to listen to onto that PC every time.

For me NAS is not a bad solution, as most of the NAS are running customized water-down Linux already. On the other hand I am in no capacity to say it's the ideal solution. Comparing to a normal PC, NAS runs less function if you ask me. I have 2 NAS at home, one for normal PC backup and remote file server with I have a lot of packages running. For the Hi-fi designated NAS, I have only the Synology Media Server, Minimserver (so Java also), and anti-virus running on top of the normal operation of the NAS. There's not really a lot of work for the NAS.

It's just my own guessing, I always prefer a faster CPU and more RAM so it can handle more if needed but at most of the time there's no need to be working in full capacity and can stay relaxed. My gut feeling is that's better than a slower CPU gets fully loaded most of the time when audio quality is concerned. For all the functionalities and capacity the NAS manufacturers are marketing, audio file streaming and streaming only shall be a piece of cake, even if hi-res files are concerned. Also NAS, especially if you go up to the SMB-level NAS, they're designed for 24/7 operation.

I have my criteria for choosing NAS, the most important is that its power supply can be easily changed. That's the reason I am contented with Synology DS412+, but not going up to DS1513+ which it can run RAID 6, or RAID 5 with spare hot swap. DS1513+ is using an internal power supply, while DS412+ was (and still is) the highest model in the Synology lineup which the power supply is not in the chassis (I know there are still SMPS inside the NAS but at least got some of the contamination by the large switching transformer eliminated).

This is the same criteria when I choose routers and switches.
