Linear Tube Audio: Bringing Vintage Sound to the Modern Era

Introduction

When it comes to audio equipment, there's a certain charm and warmth that vintage gear brings to the table. But with modern technology advancing at an astonishing pace, is it possible to marry the two worlds? Linear Tube Audio (LTA) is a company that aims to do just that. Founded in 2015 by Mark Schneider, LTA has been making waves in the audio community with their unique approach to tube amplifiers and preamplifiers.

The LTA Philosophy

At the heart of LTA's philosophy is the belief that great sound comes from simple, well-designed circuits that use the highest-quality components. The company's approach to tube amplification involves using low-power tubes in a single-ended configuration, which provides a more natural and organic sound compared to the more common push-pull design. Additionally, LTA's preamplifiers use transformer-coupled circuits, which further contributes to their signature sound.

The ZOTL Amplifier

LTA's flagship product is the ZOTL Amplifier, which stands for Zero-Hysteresis Output Transformerless. This unique design eliminates the need for output transformers, which are a common source of distortion in tube amplifiers. Instead, the ZOTL uses a patented transformer-coupled output stage that provides a clean, transparent sound with a wide frequency response.

Features and Specs

The ZOTL Amplifier is a Class A/B design that uses a pair of EL34 tubes in a single-ended configuration. It delivers 25 watts per channel into 8 ohms, with a frequency response of 10 Hz - 50 kHz. The amplifier also features a headphone output and a preamp output, making it a versatile addition to any audio system.

The MicroZOTL Preamplifier

LTA's MicroZOTL Preamplifier is a compact yet powerful preamp that uses the same transformer-coupled technology as the ZOTL Amplifier. It features three inputs and two outputs, with a frequency response of 10 Hz - 50 kHz. The MicroZOTL's compact size and low power consumption make it an excellent choice for desktop audio setups or as a headphone amplifier.

Tube Rolling

One of the unique features of LTA's products is their compatibility with a wide range of tubes. Tube rolling, or the practice of swapping out tubes to achieve different sonic characteristics, is a popular pastime among audiophiles. LTA's amplifiers and preamplifiers are designed to work with a variety of tubes, giving users the ability to tailor their sound to their preferences.

Customer Reviews

LTA's products have received positive reviews from both customers and audio critics alike. Many reviewers praise the company's commitment to high-quality components and simple, elegant designs. The ZOTL Amplifier, in particular, has been noted for its transparent sound and wide frequency response.

Customer Support

In addition to their high-quality products, LTA is also known for their excellent customer support. The company offers a 30-day money-back guarantee on all their products, as well as a three-year warranty. LTA's website also features an extensive FAQ section and a support forum where customers can get help with troubleshooting or technical issues.

Conclusion

Linear Tube Audio is a company that is committed to bringing the warmth and charm of vintage audio to the modern era. Their unique approach to tube amplification and preamplification has garnered attention and acclaim from audiophiles around the world. With their focus on high-quality components and simple, elegant designs, LTA's products are a must-try for anyone looking to add a touch of vintage sound to their audio system.
