What’s An ADC?
ADC stands for Analog To Digital Converter. Since computers only process digital information, they require digital input. An ADC, such as the Cosmos ADC here converts an analog input into a digital signal to process on the computer system. It is widely used by professional reviewers and audio enthusiasts to measure their audio gears.

High-Performance ES9822Pro ADC Chip
The brand new E1DA Cosmos ADC adopts a high-performance ES9822Pro ADC chip from Sabre Technologies. It serves as a high-grade signal converter chip to provide precise measurements with low distortion in the signal.

Premium Audio Components
What good is a HiFi audio gear without high-quality components especially when it comes to DAC or an ADC? The Cosmos ADC features high-quality audiophile-grade components on its audio motherboard that consists of premium OPA1612 OPAMPs, Susumu and Viking Resistors, Samsung COG Capacitors, Taiwanese switches, and more.

Superb Build Quality
E1DA is widely known for its well-built audio gears. The Cosmos ADC is no different here, it features a premium look with Black anodized aluminum chassis with a smooth sandblasted finish. Simply Exquisite.

Price & Availability
E1DA Cosmos ADC is priced at 159$.
