Linear Tube Audio MZ2 - Headphone amplifier and 3 input preamp with Linear Power Supply [optional remote available @ +$400].

Hand-built using quality premium components, the MicroZOTL MZ2 headphone amplifier and preamp delivers stunning, award-winning realism and sound quality designed to last a lifetime.

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.

A new feature of the MZ2 is an on-board jumper that allows the user to switch between using 6SN7 and 12SN7 tubes.

We also now offer premium DC cables for the connection between the amp and the power supply. Visit the cables section of the shop to purchase.

The MZ2 is also an excellent preamplifier. It has outputs that enable it to drive tube amplifiers as a Class A preamplifier.

The MZ2  can even drive efficient speakers via its speaker outputs (89db or higher sensitivity) to moderate levels in offices, bedrooms and other small rooms. Read Stereophile Magazines May 2016 review here.

The MZ2 includes a Linear Tube Audio 'Linear Power Supply' (see below).

A LINEAR POWER SUPPLY MADE SPECIFICALLY FOR THE MICROZOTL2

Our latest linear power supply. A high-performance design that incorporates a premium Belleson regulator.

Our standard DC umbilical is a high-quality, low resistance cable terminated with 5.5 x 2.5 locking barrel connectors. The standard length is 2', for those wanting to place the PSU near the amp, and we offer a 4' option for those who want more flexibility. See our other DC cables offered on the Shop page for more options.

Though designed for the MZ2, this is an excellent power supply for any component that requires 12V and 2.5 or fewer amps. We are happy to make you a custom DC cable for any use if our standard 5.5 x 2.5 connector isn't what you require. Contact us via email for this option.

120v (+/- 10%) / 220v (+/- 10%), 50-60hz: Manually selected by switching fuseblock in AC input assembly.
(Voltages printed on fuseblock not reflective of actual voltage.)

12" x 3.25" x 4.25"
