"The successor to David Berning's original micro-ZOTL, the MZ2 continues to offer what Berning intended it to: an introduction to ZOTL technology.

Equally a headphone amplifier, integrated amplifier, and preamp, the MZ2 is considered reference-grade for powering almost any headphone, as a 1 wpc amp for extremely efficient speakers, and as a preamp performing well above its price.

Hand-built by our small team just outside of Washington, DC, each MZ2 involves 12 hours of delicate work, including precise hand-winding of several proprietary components, and several days of burn-in and testing.

While technically an OTL amplifier, not having traditional output transformers, the MZ2 is an entirely different kind of circuit that is able to achieve low output impedance and low-current tube operation, which translates to easy matching to almost any headphone or speaker and a very long tube life. ZOTL technology results in amps with the transparency of OTL without the many limitations of OTL designs: purely tube amplification that achieves a theoretically ideal turns ratio and happily interacts with speakers from 2 to 16 ohms, or above. Headphones from 16 to 600 ohms are powered without any hum."
