I am streaming from a Blue sound Node 2i into my 2002 Roksan Kandy mkIII, feeding Dali Oberon 5s. I’m hoping to move into a detached house soon and will be able to unleash a bit more volume. Is the £600 I’m considering spending on the Dali E12 sub going to have as much an impact on the scale of the sound or might I be better looking at buying a £600 amp? I’m thinking £600 might not be enough to improve on the Roksan?
