Just a heads-up on the PX5 DSS transmitter.
Tested with the ATH-A900X and the noise floor is very, very low!
At high listening levels there is none. Only in the last 1/3 of the volume pot, there is very slight noise, but it's hardly hearable when no music is playing and it's way too load of a volume to use anyway.
In comparison to my PC soundcard output, it's might and day in terms of noise!
Very impressive in this regard as I believe the 900X are rather sensitive.
