Im considering going all out and making a proper system. I dont have a massive budget but Im thinking of going second hand and picking up much higher quailty equipment for reasonalbe cash. So whats the difference between the 565 and 568? Is the 565 still alot better than what im going to get out of say a Denon/Yamaha £1000 all in one AMP? Yes I know I will need power Amps.
