My crack is dead quiet at minimum volume up to about 1-2 o'clock on the knob. But when I turned off the music and maxed out the volume knob...around 2 o'clock there was some slight hiss...kinda like a white noise and grew louder as I maxed out the volume knob.
Not complaining because I would never set the volume at 2 o'clock (too loud) anyways, but just curious what noise could that be ?
Is that the hiss coming from the Asus Essence ST source ? That would be my guess
Would one method to tell is by disconnecting the RCA from the input on the Crack itself ? Please let me know what other methods I can test to determine the source of the sound.
However, I just found the below on the Crack FAQ page - so this is nothing to worry about ?
5. When I turn my Crack all the way up, I hear some noise, is this normal?
Generally yes, there will be some noise with the volume control at its maximum level. The amount of noise will depend greatly on the impedance of the headphones, but the important thing to remember is that this is well beyond a comfortable listening level.

Is there a specific question here beyond what is addressed in the FAQ?
It might help to do a web search on "signal to noise ratio" and do a bit of reading.

Thanks PB
Was more of an anxious post
Went home and disconnected the RCA from my computer DAC -- now im there is no hiss/white noise. Just pitch black sound
I suspect is my average Asus DAC and computer causing the noise

Computers have notoriously noisy grounds, so that makes sense.
