MicroZOTL Level 2

About the MicroZOTL Level 2

The LTA MicroZOTL Preamplifier Level 2 is an advanced Class A tube preamplifier and headphone amplifier utilizing patented ZOTL (Zero-hysteresis Output Transformer-Less) technology. It features a sleek black aluminum chassis designed by Fern & Roby, measuring 17" W x 12.4" D x 4.2" H and weighing 14 lbs. This model includes four stereo RCA single-ended inputs with high-quality Cardas connectors and one XLR single-ended input with transformer-coupled balanced option using Lundahl transformers. The Level 2 upgrade enhances the preamp output capacitors with premium Clarity CMR types optimized separately for headphone and preamp outputs, and upgrades the power supply capacitors to Mundorf Mlytic AG capacitors, increasing total power storage by 22,000uF. The internal circuit board is a high-quality ceramic board with 2 oz. copper traces, minimizing parasitic capacitance and dielectric constant for improved transparency and presence. The preamplifier offers flexible control via a metal LTA remote, allowing adjustment of volume, input selection, balance, and gain offset per channel. The unit is noted for its extremely low noise floor, excellent dynamics, and detailed, clear sound reproduction. Tube complement includes 2x 12AT7 input tubes and 2x 6SN7 or 12SN7 output tubes, selectable via a switch. The preamp outputs and headphone outputs are separated and optimized for their respective functions. Overall, the MicroZOTL Level 2 delivers reference-level sonics with a quiet, dynamic, and musical presentation suitable for demanding audiophiles.
