I have a BlueSound Node 2i. Would this hook up to my BlueSound? Has anyone done a true blind test? This would require someone to change the connections to do an A/B comparison without the listener knowing the source by doing a random switching back and forth. Try to stump the listener and then tell them which connection was what. Some of these expensive add on little noticeable difference. Kind of like splitting hairs in my opinion. Which is more noticeable, upgrading speakers or amplifiers or using this add on?

Has anybody compared these units, is there a notable difference in sound quality between these two? Both still connect to the DAC via USB.
