No, but I would be very surprised if there were any sonic benefit to moving to a streamer. The asynchronous nature of the Arcam's USB input should make it a superior connection and although the benefits of this might be offset by the noise thrown out by most computers, in your case your custom built PC, dedicated to audio I assume, is probably not particularly hamstrung by this. Of course a top line streamer with a really sophisticated on board DAC might outperform your set up, but not the Cambridge I wouldn't have thought.
