如果各位師兄有興趣，我可以帶LUMIN到府上作客，一試直解DSD的威力！請PM聯絡安排。

各師兄也可到以下地點 ...

Ching, 部機除了用uPnP protocol連接外, 請問能否用CIFS / NFS連接?

uPnP好像受high grade 的LAN cable(e.g. CAT 6/7)影響, 而WIFI更不大建議. 對嗎?

個app好似有啲bugs,叫人地用住其他upnp嘅apps先。

bug 總有，Windows 都長期有 bug，但係睇得出個 app 好認真

"uPnP好像受high grade 的LAN cable(e.g. CAT 6/7)影響"
uPnP 同 cat 幾 LAN 有乜關係?

Obee兄, UPNP是用UDP, 如果real time play audio時, drop/lost packet應會影響效果.

Reference: Wikipedia Universal Plug and Play
(UPnP uses HTTP over UDP (known as HTTPU and HTTPMU for unicast and multicast). HTTP communication usually takes place over TCP/IP connections. The default port is TCP 80, but other ports can be used. This does not preclude HTTP from being implemented on top of any other protocol on the Internet, or on other networks. UPnP uses UDP due to its lower overhead in not requiring confirmation of received data and retransmission of crc failed packets.)

Oh I see, thanks!
Actually, I was thinking the UPnP using in here is just for control of the player, not for transmission of audio data.

通用即插即用（UPnP）是由通用即插即用论坛（UPnP™ Forum）提出的一套网络协议。该协议的目标是使家庭网络（数据共享、通信和娱乐）和公司网络中的各种设备能够相互无缝连接，并简化相关网络的实现。

其實現在大部份network media player的DAC好像亦是用DLNA/UPNP(因要給一般用家作plug and play setup), 所以我估算很多Ching說轉audio grade CAT 7有很大效果.

但如用有error detect & correction的CIFS/NFS直接讀music file, 不知到底audio grade 的CAT 7還用有很大效果嗎?

UPnP has many functions. UPnP AV is for streaming. It uses TCP (HTTP).

psme兄, 請教如用audio grade CAT 7 /normal CAT 5e LAN cable由NAS接LUMIN, 效果會不會有大分別?
