O.K. all you clever people out there in forum land, I bought a set of Logitech Z3 speakers and plugged them in using the headphone socket on my KN7000. As you know, this cuts out the onboard speakers and I must say I am very impressed with the sound quality. I agree, that the sounds are much brighter and also the base is more prominent.
Now for the question. Have I done the right thing connecting to the headphone socket or should I have taken the connections to the main out sockets on the rear of the keyboard.

A very happy new year to all players out there.
