I completed the crack w/o speedball. Tested it for few weeks, with no problem sounding great. But after few weeks of use I started noticing a hum. did not use it for a while, I then used two different DACs and even moved it away from speakers and wifi, tried laying the crack on the floor away from everything. The hum persisted, I always start from 0 volume but just at 7o' clock I start hearing the hum. It's too loud to bear. I switched back to my solid state headphone amp, I don't hear the hum that I was hearing with the crack. Hope it is just a minor problem
Humnng despite transfering location of the crack

What source are you using when you're experiencing this noise? Can you describe the noise more specifically? Generally when we refer to hum, that's a 60Hz tone. If you listen to a 60Hz tone, is that what you're hearing through your Crack?
Can you post some build photos?
Hum with the volume knob up and noting connected is not a sign of problems, but 60-70Hz hum with a source connected is certainly something to look into. I would also double check that what you're hearing isn't 120Hz buzz.

I think I found the problem, I used a different RCA cable and had it route from the DAC away from the other cables ( ran it through the front and not at the back with other RCA and power cables).
Sounding good again. Wires bunch up together has really big effect to the signal.
