It seems that they are claiming that this device will increase the SQ streamed via an Echo device when connecting it to a high quality stereo system!
However, they are very sketchy on explaining how this happens.
An Echo device (such as Dot or Input) has two outputs - a 3.5mm analog connection and BT.
If the Echo Link is fed using the 3.5mm connection then you have already run it through the (presumably) inferior DAC of the Input or Dot.
If it uses the BT, then the signal may remain digital until the Link gets it, but to my knowledge the Dot/Input does not offer some "gee-whiz" BT format.
It seems like from a theoretical standpoint the Dot/Input will be the weak link and I don't see how the Link can successfully make the signal better!
What am i missing?
Thanks!
Edit: All of this said, I have been quite happy using Echo devices as streaming sources for casual listening; however, I suspect if I critically compared it to direct CD playback I would recognize the lower resolution it tops out at.
