Got some dynaudio 72s which seemed too much for my old aura 50 amp. So bought a 2nd hand krell kav300i for £930. Difference is huge. Has the muscle to really whip those babies into line! Especially in the base. So now have a dyn 72, kav300i, rega planet cd set-up. What next? my cables/interconnects etc are nothing special. Would a cd upgrade make much difference. What about seperation (squash balls etc), speaker levelling, placement. Just looking for some tips to make the sound even better.....
