Value of Adding Bridge II to Direct Stream DAC

Hi All.  I've got a PS Audio Direct Stream DAC running the latest (Redcloud) firmware, with a good deal of both power supply and digital signal purification in front of it (including a Singxer USB=>I2S converter).  This additional "cleaning" improves the sound, which is already quite good.  I'm curious about how adding a Bridge II would affect/improve sound quality.  I understand it means that I would no longer use the USB connection between the computer and the DAC. Most of my music is played off a hard drive connected to my Mac Mini, though I've been streaming Tidal a bit lately using Audirvana.  I'm mostly interested in effects on SQ from the hard drive, but also interested in effects on streaming from the net.  If anyone has made this move, can you tell me what you've observed regarding SQ changes?  Thanks, Peter
