Just out of curosity I opened the Quad cdp to get a feel of the internals and quality of components. The cdp is very laid out with a huge toroidal transformer, good sheilding and good use of quality components.
What struck me was the variable vol control. It is made up of 4 relays which switch on/off resistive network to attain attenuation followed by a buffer. The total # of steps is 32.
very good implementation of the vol control.
