Our ZenPro Audio converter test is the most in depth AD/DA comparison on the planet. The test enables USA customers to hear a direct comparison of what a 24 track musical project will sound like compared to dozens of others when confused about which brand or model to buy. We are constantly able to add and update new models since the test is 100% repeatable and purpose built.
PreSonus has done a great job on the new Quantum series, and have upgraded their Studio USB-C series as well. You can hear them both to decide!
