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.


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

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.


The products you guys build really hit my soul.
