I have seen varying user reports of the advantages of adding a Cambridge Audio Dacmagic external DAC to the Squeezebox classic. Quite a few people say it makes a bigt improvement but a few others say they did a-b comparisons and returned the Dacmagic because it didn't make that much difference. Has any consensus emerged on this as I recently bought a squeezebox classic and feel it lacks punch and clariy compared to my Arcam CD 73 CD player ?
