Powered by premium EL84 tubes, delivering 12 watts per channel, listeners enjoy startling realism, plentiful bass, low noise, plus gorgeous mids and highs.

“You can just wander around inside a recording with this amplifier.”

Integrated with your life

We get it. You want the best sound you can get, but you don’t have the space, or desire, for separate components. With five inputs, LED display, brass touch buttons, home theater mode, and remote control, the Z10 Integrated amplifier gives you world-class sound that fits into your life.

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.” ZOTL amplifiers give you the best of both worlds: beautiful tube tone with the clarity of solid state (while being entirely tube-based).

“The Linear Tube Audio Z10 is a very special amplifier, and one I won’t soon forget. It combines the allure of tubes with the precision of a solid-state amp.”
— Steve Guttenberg / CNET

Patented perfection

The Z10 Integrated amplifier is based on David Berning’s patented ZOTL technology. For a technology to be patented, it must be deemed “new, useful, and non-obvious.” We think that sums up our approach quite nicely.

Looks as good as it sounds

The low-resonance aluminum chassis of the Z10 Integrated is designed and manufactured 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.

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. Ohno OCC wiring. Vishay Dale resistors. Mundorf caps. Typically, these are names you’ll only hear in amps that cost $10k or more.

Never buy another set of tubes

Most tube amplifiers run through tubes every 1,000-2,000 hours. That sounds like a lot until you consider that we estimate tube life for our amps to be in the 10,000-20,000 hour range. Why? Because we use ⅓ the current through the tubes, which results in lower heat and dramatically longer tube life.

“I would put the Z10 Integrated up against anything I’ve ever heard with a high degree of confidence.”
— Satisfied LTA Customer

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.

Quality assurance

The Z10 Integrated amplifier is hand built by technicians with years of experience building the complex ZOTL circuits. All our products are backed by a 2-year warranty and a 14-day no-questions-asked return policy.


Part-time Audiophile Editor’s Choice Award

“There’s a delicacy and authenticity to the Z10 Integrated that can’t be ignored. You’ve probably heard reviewers say how sorry they are to see certain components leave, but I feel like I have a hole in my heart where this equipment once made its home for a few brief and worthwhile months.

Highly recommended.”

6 Moons Review

The Audio Beatnik

The Z10 has a very realistic musical presentation. It plays music with wonderful harmonics and richness but with musically quick transience and exceptional bass control. Mentioning the bass, the Z10 was able to carry the music with a really good rhythmic drive. The bass was also very well defined, very tight, and there wasn’t the least hint of a “one-note bass.” There was also a very natural air around and within most of the bass instruments.

The Z10 does its magic in the midrange, which is where the Z10 breathes life into the recording. I could hear small differences in voices and breathing, and the instruments had a rich harmonic structure. On piano solos, it was much easier to hear the differences from one piano to the other.”


LTA amplifier owners have found great enjoyment using their amps with a variety of speakers outside of the below ranges. The below are guidelines, not rules.

Critical listening environments: 90db sensitivity and above

Smaller rooms / lower volume levels / non-critical listening: 88db sensitivity and above

If you have questions about your specific speakers, chances are someone we know has tried them. Don’t hesitate to reach out with questions about your specific setup. Also, don’t forget we have a 14-day no-questions-asked return policy.


LTA is excited to announce the first Berning-designed integrated amplifier. With all the magic, realism, and 3D soundstage of ZOTL technology, the Z10 Integrated amplifier delivers the experience of a live music performance right in your living room.

A single component solution, the Z10 Integrated amplifier incorporates the acclaimed ZOTL10 power amplifier, a Berning designed preamplifier, LTA’s digital control system, and an optional phono preamp – all beautifully packaged in a Fern & Roby designed case.

The Z10 Integrated amplifier offers all the benefits of the output transformer-less ZOTL technology: three times the tube life and one third the heat. With startling realism, plentiful bass, low noise, and gorgeous mids and highs – the Z10 Integrated amplifier is the perfect package.

The brass touch buttons, headphone outputs, easy-to-read, configurable display, and machined aluminum front and rear panels, exude the high quality manufacturing of handmade products in the USA.

The heart of the Integrated Z10 is the highly-acclaimed ZOTL10 power amplifier, using EL-84 power tubes at 12 watts per channel. With the addition of a preamplifier borrowed from Berning’s $30K product, the existing ZOTL circuitry cross-couples to a gain stage, and matches perfectly with the power amplifier.

The amplifier is wrapped in our new control system featuring: 5 inputs (including one true balanced input,) tape in and out, LED dimmable display with configurable time out, LED input indicators, home theater mode, remote controlled stepped attenuation using premium Vishay Dale resistors, and a linear power supply configured with a Belleson regulator for extremely low noise. Additionally, the Integrated Z10 comes equipped with two headphone output jacks: a high output for less sensitive headphones and a low output for very sensitive headphones.

Delivering much higher power than solid state amps with the same power rating, ZOTL tube amplifiers can drive your 90db and above sensitivity speakers to thundering levels with headroom to spare. Providing everything you need except speakers and a source, in a sleek new case, the Integrated Z10 is designed to last a lifetime.
