How does Duet 3 compare to other Apogee units?

The following comparison chart highlights how the Duet 3 measures up against other Apogee interfaces across key specifications.

1. 65dB of gain covers most Mic Pre requirements. Many classic Mic Pre's have 60dB. Competitive interfaces in the market have 65dB Mic Pre gain.
2. We traded off better dynamic range which is audible for a slight increase in THD which is inaudible. As a point of reference, THD of -103dB on the Duet 3 is 0.0007% and -106dB of the Duet 2 0.0005%. It would need to be around 1000 times higher to be in the audible range.
3. The Duet 3's analog-to-digital (A/D) converter delivers 5 dB more dynamic range than the Duet 2, letting you capture finer detail and greater depth in your recordings. Its A/D dynamic range is comparable to that of the higher-priced Ensemble interface — a remarkable achievement at the Duet 3's price point. The Duet 3 also edges out both the Duet 2 and Ensemble in output dynamic range.
4. While the Duet 2 and Duet 3 share similar headphone amplifier specifications on paper, the numbers alone don't tell the full story. The Duet 3 features Apogee's acclaimed zero-ohm headphone output design, which enables it to drive even the most power-hungry headphones with exceptional sound quality and high output levels.
