....except, everyone seems to forget that the OP stated that the volume of the integrated amp is at Zero
The volume control is at its lowest setting. That may not be off but attenuated enough to not hear music playing.
What cause tweeters hiss ?
I could hear hiss sound when i place my ears close to both tweeters (ATC SCM 11 speaker) when Denafrips Ares II is connected with interconnect (XLR or RCA) during power on/off/standby. Hiss sound disappear only until power cord is disconnected.
At first I thought it’s amplifier (Accuphase E280), then I bypass Ares II and connecting Sony CD player with RCA out to amplifier, no hiss can be heard from tweeters.
Due to curiosity, i connected my Topping D90 with similar arrangement, I could hear hiss sound until I unplugged power cord.
During the above test, music is stopped, amplifier is turned on but at zero volume. All my music source, DAC, amplifier are from the same power source/circuit with Novaris Power Filter.
Can’t hear the hiss at my usual listening spot though.
What could be the culprit that create this hiss, DAC ? Grounding Issue?
