Creative has also used high-quality capacitors to ensure clear and consistent sound quality. Realistically, few people are likely to swap out the National Semiconductor LME49710 single op-amps and JRC 2114D dual op-amps for different chips, but the option gives you the potential to tweak the sound to your own requirements. The op-amps drive and amplify the analogue sound that’s output to your headphones or speakers. Like Asus and Auzentech, Creative uses swappable operational amplifiers (op-amps), which means that serious audio geeks will be able to easily upgrade the card with their own preferred hardware. However, it’s a popular choice for consumer-level sound cards and we have no complaints about the quality of its sampling. As this isn’t an audio production card, the ADC is more likely to be handling voice input for Skype calls than recording the next great rock opera. The Analogue-to-Digital Converter (ADC) is a 4-channel Wolfson WM8775SEDS. Meanwhile, the Digital-to-Analogue-Converter (DAC) is a Burr-Brown PCM 1794A, which is the sort of chip we’ve come to expect from high-end sound cards, AV receivers and amplifiers that target audio enthusiasts.
