In my case I've run through two different setups: Setup 1: Wireless SB3 analog out to Paradigm Active/20s (self-amped speakers). The noise level does not seem to chage when I raise or lower the volume on the SB3 (muted through 40). Right-channel noise/interference level appears to be the same whether the SB3 is playing (though it's difficult to tell), paused, or "off". The only thing that affects the right-channel noise/interference is the display brightness. Setup 2: SB3 analog out to my Proceed AMP5, AMP5 to my B&W 703s. Same results. In both cases the SB3 is used as my volume attenuator so I can't run it at max level while playing music. However, the fact that the noise level does not seem to change when I raise or lower the volume while it's not playing strikes me as odd. I've tested and eliminated the following possible culprits: - Audio cables (swapped cables, same result) - Local interference (moved SB3, same result) - Speaker issue (swapped channels, switched in B&Ws, same result) - Wireless connection (switched to wired Ethernet, same result) - Power supply interfering w/amps (moved plug to a separate circuit on opposite side of the room, same result) - AC line noise (plugged directly into my PS Audio UPC-200 line conditioner, same result) Digital out seems to be fine (though I'm wary about the digital coax after I ran into problems on my DAC. Toslink has worked well). Is it possible that the display is throwing off some interference that is being picked up by the right analog out (and the headphone output) after the attenuation stage? Can you locate my returned SB3 and give it a try? Or maybe grab a new wireless SB3 off the shelf and see if it exhibits the same noise? I'm sure you would have noticed this before if this issue existed from the beginning. Perhaps it's just a funny production batch? Or maybe a slight change in a vendor's part that's different from the original pre-production run? It's worth noting that my first SB3 only arrived last month and this replacement obviously is just about as new.
