Sonic Frontiers SFCD1 Issue

I have come to this community for some sound advice.
I have a Sonic Frontiers CD1 with the left channel creating a wooshing noise heard mostly through the tweeter because of the higher frequency. The noise only happens when music is playing and is volume dependent, gets louder as the volume is increased/decreased. The music is playing flawlessly, with overlaying sound rushing or whooshing, only way I can describe it. I thought it could be dirty contacts on the relay of the left output stage and have replaced that relay with a new one. Sadly no improvement. If it is the DAC I am going to be in trouble since they are no longer in production. Any ideas people? It would be much appreciated.
