可否推介一些升檔軟件? 謝。

I have used several and which one to choose depends on personal requirement and preference.

XLD is still free.
http://tmkk.undo.jp/xld/index_e.html

The old Korg Audio Gate was also free but the new one version 4 has numerous limitations. If you do not mind such, it is still good.
http://www.korg.com/hken/products/audio/audiogate4/download.php

Max was free but now need to pay. it provides a free trial.
https://cycling74.com/downloads

Audio Inventory. it provides a free trial as well. The Pro version is close to HK$2000

Saracon by Weiss
Years ago some professionals used this one. It is expensive. You may contact Kent Poon of 方浪。

There are other ones (search Google) that I have not tried. May be good or even better, don't know.

"a)NAS -> diamond USB -> 105D
b)Nas - >rounter>普通 lan線 -> 105 D

當然Lan綠好.  NAS 的noise 經USB (5V) 影嚮105D. 同樣, 用AQ (not diamond) USB3.0 harddisk cable直駁harddisk, 105D 也受harddisk的noise影嚮."
============================
這個情況好似我。
因為NAS離OPPO 105好遠,就用了 USB3.0 cable直駁harddisk入 OPPO 105,以為覺得咁樣最好聲。
咁如果用 b)Nas - >rounter>普通 lan線 -> 105 D方案

我情況按下面接法是否教為合理?

Router>普通CAT5E lan線>Switch>CAT7lan線>OPPO 105>AMP(DAC)

Sorry, i have not used JRiver therefore I am unable to outline the difference or benefits, if any.
I have a feeling that JRiver is basically for PC and I use a MacBook Pro.

Additional point on upward sampling that is based on personal view and NOT empirical A/B comparison.
Instantaneous upward sampling whilst playing the track (they call this resampling “on the fly”) takes up processing power of the CPU and at the same time playing the track takes up power as well.
24/352.8 (DXD format) has excellent sound based on A/B comparison. If one uses a 16/44.1 CD track and wants to upward sample it on the fly to 24/352.8 and plays it at the same time, the CPU of the computer/server may not have the proper power and speed to do both tasks just as well. If that is the case either task would suffer and the resultant sound is NOT as good as playing the CD track already resampled to 24/352.8 before hand.

JRiver upsample from PCM to 5.6DSD is only using <8% of my cpu power (6gen i5 laptop).

Not really related, PowerDVD7 on the other hand using 7x % of my cpu power and even chrome is laggly.

I see.
Perhaps you would like to pre upward sample a track and play it; then play the same track with conversion on the fly and compare the sound of both. Please tell us the result.
I do not have an upward conversion software that does it on the fly and therefore am unable to experiment.

Agree.  The power required for up-sampling on the fly should introduce electrical noise as well.

試吓NAS =LAN=> SOtM sMS-200 Ultra =USB=> DAC

有驚喜!

"… Instantaneous upward sampling whilst playing the track (they call this resampling “on the fly”) takes up processing power of the CPU and at the same time playing the track takes up power as well.

The above point from Momei is the reason why dual PC setup is much more preferable than single server PC for on-line upsampling playback. The second PC or streaming device is connected through local area network using network streaming to achieve asynchronous USB mode for connecting to DAC such that jitter can be eliminated to a significant extent.

In case if HQPlayer is used as the upsampling software, the second PC or streaming device is called the NAA (Network Audio Adapter). I believe that this kind of setup for HQPlayer can help to achieve much better sound quality and partly accounts for its high quality playback performance.
