I got my canamp like 4 hours ago and I was wondering if it was normal when I turn the volume to max when nothing is running to hear the humming sound? my soundcard is a really old soundblaster and I don't have an external dac so I think the source is to blame. and is there a certain way to unplug the headphones from the amp? like turn it on then plug it in and then when your done, turn it off and then remove the phones....or remove first and then turn off.....or what?

to see if the hum is from your soundcard, unplug it from the amp and turn up the volume

i generally have my headphones plugged in when i turn it on or off, don't know if there's strict procedure

upgrading from my previous LD2+, i'd got used to turn the volume knob all the way down, plug in the headphones, set to normal listening volume again.

same goes to disconnecting my headphones from my Heed.

Mine' the opposite. When I turn down the volume and no music is playing, I hear a radio signal through my headphones. not too much on my K601, but moreso on my Grados.

i tried unplugging it from the soundcard and the hum was just barely audible so the card was making it. but the very very slight hum....is that from not having the amp grounded or something? i really don't have any idea of what i'm talking about

Get a cheater plug ($2 at Home Depot) and rotate 180 degrees. If the hum goes away you are done my friend.
