I hope it is clear by now how good, in my opinion, the Weiss DAC501 is. Adding this device to your system will likely significantly improve its performance. Either because it will be a better, more resolving, open, spacious, precise and yet natural sounding source than the previously owned one or due to the DSP that will help you fix specific issues or enhance listening experience. Either way, I don’t see how you could go wrong choosing the DAC501. Especially that it is also more than decent headphone amplifier and digital preamplifier, which could save you quite some money as you won’t have to purchase separate components. If you have a chance give it a try! I am adding the Weiss DAC501 to my list of highly recommended components and I definitely wouldn’t mind using one in my system.
