A very special amplifier... It combines the allure of tubes with the precision of a solid-state amp.
— Steve Guttenberg / CNET


Tube tone + solid state detail

Traditional tube amps are known for their liquidity and linearity, but their “warmth” masks details and can sound thick. Solid state amplifiers give you that detail, but can be “clinical.” LTA amplifiers give you the best of both worlds: beautiful tube tone with the clarity of solid state.

Patented perfection

Linear Tube Audio’s amplifiers are based on David Berning’s patented ZOTL technology, the only advance in tube technology since the 1950’s. For a technology to be patented, it must be deemed “new, useful, and non-obvious.” We think that sums up our approach quite nicely.

The quietest amp I have ever heard; not the quietest tube amp, but the quietest amp.
— The Audio Beatnik


Premium components = premium sound

If you use cheap, generic parts, guess what kind of sound you’ll get? That’s why we use only premium, name-brand components. Belleson regulators. Audience OHNO wiring. Vishay Dale resistors. Mundorf caps. Typically, these are names you’ll only hear in amps that cost $10k or more.

Made in the USA

Every LTA product is designed and built by hand in Takoma Park, Maryland, by a group of technicians who are also musicians, audiophiles, and music lovers. Some of whom have been with us since the company’s earliest days.

The products you guys build really hit my soul.
— Tom W. | LTA Customer
