Sony SCD-1

I've used an SCD-1 for about 3 months. Never experienced anything like what you describe. Stating the obvious: have you checked all cable connections? Is the hum in both channels? Sounds like you've got either a cable problem (especially if hum is in one channel only) or defective unit.

Good luck,

Try to see if there is a switch to turn off the balanced outputs. If there isn't a switch, get a gold jumper pin from an audio dealer, and place in the balanced output pins. Also, make sure you don't have interconnects or speaker cables near your power cords.

you might have the sony set to 'custom' instead of standard. i konw this can cause a hum in the 777es. also, your ground circut might not be working with the sony so try using a two prong end plug for the power cord without and that should do it.
