Wayne is a great guy from my experience. He's passionate about audio and loves his Squeezebox. I am never going to argue with anyone about what they can or can't hear. I've never heard a stereo system that could reproduce the sound of, for example, a tuning fork two inches from my ear. It is 100%

The SB2 is my favorite toy too! I'm completely pleased with my purchase, and would recommend SB2 to anyone that has a network and a stereo. I think the SMPS included with SB2 is a good choice, adds value, works well. A good linear supply would add too much too the price. For those that want to

Yes, time and amplitude are missing. Apparently it's "taken from the 5 volt line feeding the DAC." Would probably be difficult or impossible to see any output variance with a music signal. Since when do audiophiles care about that. ;) Regards -- Music Machine ___
