I am a Outlaw newbie. Recently jumped on a 950 after the Soundhound version was announced. My 950 has only been in operation 3 days so far. BTW my unit has no dots, but the serial # starts off with 02. No noticeable hiss or humm so far and I have very sensitive speakers all around. One thing I have noticed is that you really have to step on the volume compared to my old processor, but the sound quality of the 950 is far superior however.
