Linear Tube Audio MicroZOTL Preamplifier

ZOTL, or Zero-hysteresis Output Transformer-Less, is a proprietary topology that eliminates the output transformer found in traditional tube amps. This allows for a much lower output impedance and wider bandwidth, resulting in a sound that combines the warmth and harmonic richness of tubes with the speed and clarity typically associated with solid-state designs.

Yes, the MicroZOTL features a dedicated, high-performance headphone output on the front panel. With an output impedance of just 1.38 ohms, it is capable of driving a wide range of headphones with excellent control and transparency.

The ability to switch between 6SN7 and 12SN7 tubes gives you flexibility in fine-tuning the sound profile to match your specific system or personal preference. It allows you to experiment with different tube brands and variations without needing to modify the unit.

Yes, it includes one set of transformer-coupled balanced XLR inputs. This allows you to connect balanced sources while maintaining the purity of the signal path.

Absolutely. The latest iteration features an upgraded power supply and refined circuit layout specifically designed to minimize noise. It is engineered to be whisper-quiet, ensuring that even the most subtle details in your music are not obscured by background hiss.

It utilizes a high-resolution, relay-based stepped attenuator. This design ensures perfect channel balance and superior sound quality compared to traditional potentiometers, which can degrade over time and introduce noise.
