Tube MAGIC + solid state detail

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

Patented perfection

Linear Tube Audioโ€™s amplifiers are based on David Berningโ€™s patented ZOTL technology, an output transformerless design that delivers unmatched transparency and realism. For a technology to be patented, it must be deemed โ€œnew, useful, and non-obvious.โ€ We think that sums up our approach quite nicely.


โ€œThe quietest amp I have ever heard; not the quietest tube amp, but the quietest amp.โ€

Premium components = premium sound

If you use cheap, generic parts, guess what kind of sound youโ€™ll get? Thatโ€™s why we use only premium, name-brand components. Belleson regulators. Vishay Dale resistors. Mundorf caps. Typically, these are names youโ€™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 companyโ€™s earliest days.


โ€œThe products you guys build really hit my soul. โ€

Looks Good. Sounds great.

The low-resonance aluminum chassis on all LTA products are designed in Richmond, Virginia, by the award-winning industrial design crew at Fern & Roby. Brass touch buttons, LED display, and machined aluminum front and rear panels exude quality.

Quality assurance

Linear Tube Audio amplifiers are hand built by technicians with years of experience building the complex ZOTL circuits. All our products are backed by a 3-year warranty and a 30-day in-home audition policy.
