PS Direct Stream Vs. Lumin X 1 Sound quality difference?

I don't use Etheregen via optical but on 2 different purely copper based ethernet systems, it has the same great effect.  

I didn’t read this whole thread but my question is was the DS being used balanced out and volume at 100?  I certainly understand if people can’t use it that way based on their system, but IMHO  any comparisons to other DAC’s are completely meaningless otherwise. (Except as they relate to one’s own purchase decision, not anyone else’s)
