What processor is in the Acurus? 18bit, 20bit? You would want to move up in technology I would think. That means finding a 24/96 DAC or better. The Aragon is nice but older? Do you want tubes?
I would start with something like a mid level MSB and see if you like the change. They are easy to resell if you need to change the sound any more...
