I would just like to point out, that even though this is how some others achieve their bass, if you look at our tech specs:
- THD: <0.003%
- Max Power Output: 840 mW @ 25 ohms (per channel)
- Input Impedance: 15 kohms
- Output Impedance: 0.2 ohms
If we did use subharmonics, our THD would not be less than .003%... Just a friendly FYI.

No other amp increases bass in steps, rather they all just use a switch so the bass is not enough, or too much for the headphones. Can't wait for the second ZO to come out later this year. I just don't understand why this thing hasn't blown up yet and gotten very popular, especially on head-fi... there isn't much out there like it. It deserves more attention than what it gets in my opinion.
Thanks for the kind words. This project has taken us many years to work out, so any and all positive feedback is both encouraging and appreciated.
