cambridge audio np30 hesitant playback

Hello
My cambridge audio np30 streamer has problems playing organlive.com, its output is hesitant and not worth listening to.
My daphile thin client server has no problems with organlive, both are connected by ethernet to the router. I dont have a fast internet connection, about 2meg and wondered if there was any mod I could do to the np30 to get it to improve.
Thanks
