I came across an issue this evening as I sat by myself with my week old 950 and Parasound 1205. My setup:

Outlaw 950
Parasound 1205a
Paradigm Monitor 11's v.2
Paradigm CC-350 v.2
Paradigm Mini-Monitors v.2

Keep in mind that just the amp and the 950 are powered on below.

When I turn on the 950, "DVD" is selected with "Optical 1" as the source. Everything is dead silent, which is good. However, when I select an analog input like "TV", the hiss starts. This is audible from the listening position. Now here's the catch... when I switch back to "DVD" with ANY optical input, the hiss is STILL THERE! If I turn the 950 back off and then back on with "DVD + Optical X" as the default, the hiss is gone until an analog source is specified. Once the hiss is introduced, it stays around no matter what source is selected.

The hiss will not occur when the line outputs are disconnected from the 950 meaning that it's most likely not an amp problem.

Note: With the Digital SPL meter from Radio Shack set on C weighting and fast response, the reading is ~50dB at three inches from the tweeter of ANY speaker after the hiss is introduced.

Am I missing something?
