Not all the DSP systems are fully beneficial, but in many cases they are going to work better or worse in different systems. This is kind of giving them the benefit of the doubt, but often that’s the way it is with DSP systems. I feel this only scratches the surface of what this excellent device is capable of. The hardware platform is excellent, with extremely fine, very detailed, and extraordinarily even-handed sound quality (as befits a company with 30 years of pro-audio engineering under its belt), and the headphone amplifier in particular is extremely detailed and capable of driving even difficult headphones. But the performance of the Weiss DAC502 transcends mere sound quality. It’s truly a digital device for the future!
