Know before you buy
The AERO DAC uses an R2R ladder architecture that avoids oversampling and digital filtering, which often cause harshness in digital audio. By pairing this with a Class-A ZOTL output stage and zero negative feedback, it produces a more organic, natural sound that prioritizes timbral accuracy over clinical precision.
Yes, the AERO DAC is designed for easy tube rolling. It supports both 6SN7 and 12SN7 tubes, allowing you to experiment with different sonic signatures to suit your personal preference.
No, it is a true plug-and-play device. It does not require any custom drivers to function with your computer, and it is also certified Roon Tested for seamless integration with Roon software.
The ZOTL (Zero-hysteresis Output Transformer-Less) technology allows the tubes to drive your amplifier with exceptional transparency and speed. It eliminates the limitations of traditional output transformers, resulting in better transient response and a cleaner signal path.
No, the AERO DAC utilizes a direct-coupled topology that removes capacitors from the signal path. This design choice minimizes potential signal degradation and helps maintain the purity of the audio.
The AERO DAC supports PCM audio up to 24-bit / 192 kHz. It is optimized for standard high-resolution PCM files rather than DSD or MQA formats.
