Please Help!! looking to get into computer audio.

I am looking into exploring the computer audio format, I am a long time audio enthusiast. My Digital front end currently consists of a Oppo bd103 and a Bryston Bda 1 , I currently have the capability to stream my itunes library from my computer via bluetooth to my oppo player , but the sound quality is not up to my standards. Any suggestions on how to increase the sound quality would be great. Please consider that i am a newbie to this and a little confused with the formats of computer audio. Any solution would be appreciated thanks. I have been looking at the w4s remedy and or Blink or recovery. I am also considering just getting a wadia 171 ipod transport and just using my ipod. confused and not sure which route to take for best sound qaulity.
