I have several DACs that don't require vbus but still gain a SQ benefit when vbus is disconnected at the source.  The Auralic Vega  is one.

I believe my LH Labs DAC may be the same - requires the power only to make the initial handshake, then it can be unplugged until you reboot either end of the connection.  May be my imagination but I think it sounds better after the power leg (even from a dedicated LPS) is removed.

I have the geek pulse with. Geek lps1. 

Does it still require the 5v for handshake from the Lps? Am I reading you correctly? 

I am considering a curious USB and making a connector for the 5v to connect/disconnect. May I ask what cable you are using?

Yes, it requires a handshake signal, provided via the split USB cable from the LPS.  

I'm using the yellow split cable they shipped with the DAC (forget what they call it), but regularly remove the power leg from the LPS after the handshake is complete, so that only the data leg is still attached.  Would be nice to automate that part
