I am using YAMAHA RX-V473 to connect my home DLNA server. It is almost okay. RX-V473 can decode up to 96KHz\/24bit flac. However I have 128KHz\/24bit flac files on my DLNA server. iEAST SoundStream Pro is perfect answer to play all my music files on the DLNA server.<\/p>\n

Just need to follow the instruction. Brief setup process is as follow.
\n– Power on SoundStream pro. Then you can connect SSID IEAST_xxxx withoit password
\n– Open web browser to connect http:\/\/10.10.10.254 to display setup WiFi setup page
\n– Select you home WiFi SSID and enter WiFi password
\n– SoundStream Pro will connect your home WiFi and disconnect from setup screen. Original SoundStream setup SSID is still available for use. But it will be password protected. You can use same password for your home Wifi to connect SoundStream pro setup screen<\/p>\n

At the beginning, I instantly connect SoundStream pro and AV amplifier by using S\/PDIF optical cable. It should be noiseless connection. And provides better sound. But think about the SoundStream pro is using DAC to decode digital sound data to analog. This is the function of SoundStream. If I use S\/PDIF interface, analog signal needs to convert digital again within SoundStream pro. Even if I can ignore distortion\/noise of decode and encode process, the problem is specification of S\/PDIF interface. It seems to me, S\/PDIF supports up to 96KHz\/24bit PCM. It is acceptable, but implementation would be less than this…<\/p>\n

I checked AV amplifier information screen to confirm this. Sampling rate is always showed 44.1KHz.<\/p>\n

Anyway, I changed the connection to analog. Unfortunately analog connection of SoundStream Pro is 3.5mm stereo mini-plug. I would like to modify this to RCA pin jack.<\/p>\n","protected":false},"excerpt":{"rendered":"
