Hi guys, fairly new to all this, ive currently got a pioneer vsx-510 budget amp which ive had for a few years. Finally decided to upgrade. Ive gone for the canton CD1 speakers kit and would like to upgrade the amp. Would appreciate any advice & recommendations. My budget is about £300 which i know isnt a lot but ill be happy if i notice a change in sound quality / level etc.... Thanks in advance. fizz.
