When you select "No Amp", you're bypassing the HD500 and engaging the DT50 channel B preamp. So if the volume controls on the DT50 channel B are down, you won't hear anything! You can select the Topology, Class and Pentode/Triode on the amp itself to set it up they way you'd like.
As far as the "burst" of noise that happens when you switch presets, this is a bug that has been noted by Line 6, Hopefully it will be fixed with a software update soon. It is worst when you have the volume pedal less than 100%. If it's a problem for you keep your volume pedal up all the way when building your presets.
