Been experimenting with digital music with my laptop (running Foobar, streaming FLAC files) as a source, through a Musiland DAC (USB), then into a Threshold preamp, onto a Trends power amp, then to the speakers...

The problem is that I get a lot of noise from my laptops power supply. A soon as I unplug the laptop (from the PS) all noise disappears... I tried moving the PS block as far away as possible but it still makes the same amount of noise (through the speakers)...

Any ideas?  :help:
