tzh21yColoured sound can happen when the sound of preceding equipment is changed by the next piece of equipment, and so on and so on all the way to the speakers.

Ivor Tibenbrun inventor of the Linn Sondek turntable, had a famous saying,
"It all starts with the source get that as right (uncoloured) as possible and your 1/3rd of the way there"
