Jack Roberts of The Audio Beatnik reviews the MZ3


"...the LTA MZ3 is even quieter, more detailed and is the most natural-sounding amp I have ever heard. It has the same see-through quality into the layers of the music, but the scale of the instruments is even more natural, and it has an even better tone."

Terry London Reviews the MicroZOTL Preamplifier


Terry London of home theaterreview.com reviews the MicroZOTL Preamplifier.

“It was quickly apparent and astounding to me that the MicroZOTL Preamplifier produced a spatial perspective that made my seven-foot tall, 21-driver speakers completely vanish in the largest and accurately layered soundstage that I have ever experienced in my listening room.”

LTA at Capital Audiofest 2018!


Linear Tube Audio proudly presents the latest products in our audio arsenal - the Ultralinear power amplifier and the long-awaited Microzotl Preamplifier. Join us at Capital Audiofest 2018 from November 2 - 4 at the Hilton Washington DC/Rockville Hotel & Executive Meeting Ctr in Rockville, MD.

Utilizing David Berning’s unique zero-hysteresis output transformerless (ZOTL) audio design, listeners can experience an expansive soundstage, unbeatable clarity, and breathtaking realism.

Hear the new Microzotl Preamplifier and Ultralinear in room 526 with Spatial Audio and the Randolph Room with Daedalus Audio. Enjoy a sneak preview of our new Integrated Z10 in the Twinbrook Room with Fern & Roby and the classic MZ2 at our table in the hallway!

Audio Beatnik says our Ultralinear is "incredibly rich and nimble!"


"The music seems to float effortlessly in space and never seems forced or strained. The bass has a rhythm that enables music to sound very lifelike. Maybe the most important thing about this amp is how tonally accurate it is."

Introducing the long-awaited MicroZOTL Preamplifier!


Linear Tube Audio is excited to launch the new MicroZOTL Preamplifier.
Our fully realized MicroZOTL Preamplifier improves the microZOTL in many ways to provide a truly premium sonic performance. Liquidity, clarity, holographic with air and performer separation…tonality, accuracy and an ability to reproduce the energy and pace of the original performance.

Technology improvements include adding a remote stepped attenuator with the smallest step sized to ensure precise control at low levels, ceramic circuit boards for a point to point wiring sonic experience, power supply 4 times bigger with choke isolated output, ONO OCC output wire for better bass, Cardas connectors, improved output caps that expand the soundstage, an LED dimmable array display, brass touch buttons, display timeout, tape monitor, headphone output, dual preamp outs, milled aluminum front and rear panels, tubes hand selected, and casework designed by Fern and Roby.

We look forward to sharing the newest addition to the ZOTL family with you. As each amp is built to order, please allow for 10 days to 2 weeks lead time.

Order today!

LTA at Axpona 2018


Starting today and through the weekend, visit LTA at
the Renaissance Schaumburg Hotel for AXPONA 2018!


You can find LTA in several locations throughout the show. 

In Room 606 we're joined by Fern & Roby, who will have their turntables, phono stage, and speakers, and Black Cat Cables.

Room 654 combines our amplifiers with Lampizator's digital components, Daedalus Audio speakers, Skogrand cables, and a beautiful Massif Audio rack.

Room 696  also has us partnered with Fern & Roby's excellent analog sources, in addition to Spatial Audio and their X2 speaker, with Audioquest providing cabling.

In the Ear Gear Expo, you'll find us with a Border Patrol DAC, Wolf Audio Systems server, with ANTICABLES hooking everything together.  


Officially in production, you'll find the new ZOTL Ultralinear in action at AXPONA. Visit ourwebsite for more information on this unique amplifier.

Happy New Year!

It's the new year, the 18th year since the MicroZOTL originally debuted, and we're starting to hear back from those reviewing the ZOTL10 Mk.II. It has already made it onto Part-Time Audiophile's Best Hi-Fi Gear of 2017 list and Audio Bacon's Best of 2017. We look forward to reviews being published and more people chiming in. 

LTA at RMAF 2017


Had an excellent time showing with Fern & Roby at RMAF over the weekend. The system sounded great, anchored by F&R turntables and the Maverick phono stage, MZ2 and the new ZOTL10 Mk.II, and rounded out with DeVore Fidelity Orangutans and Black Cat Cables.

Axpona has come and gone and we had a great time in our room with Spatial Audio's new Triode Master M3 speakers and Lampizator's new Golden Atlantic DAC and Komputer server. Verastarr hooked us all up. 

We won't be in LA for the upcoming show, but our friends at Well Pleased AV will be using an MZ2-S as a preamp in their excellent setup. 

MZ2 + MZ2-S News

The MZ2 and MZ2-S are now available with optional remote volume control in our store! The MicroZOTL2.0 and the MicroZOTL2.0 Deluxe have been phased out and replaced by these similar units. 

We'll also be attending CanJam NYC the first weekend of February! Hope to see people there. 


Two Stereophile writers named our room at the NY Show their Best in Show. Thanks for stopping by, Ken Micallef and Jana Dagdagan.

For those who couldn't make it, we again teamed with the exciting new Wolf Audio Systems with their Red Wolf server, as well as Audience's cables and we finally got to see, and hear, the beautiful Veracity Audio Chrysalis DAC. The voice of our room was provided by Sadurni Acoustics' new Miracoli speaker, an impressive horn that we bi-amped with two MZ2-Ss. All of these things make beautiful music together, and allowing that music to sound beautiful in a hotel room were the acoustic treatments built by Resolution Acoustics, and allowing them to look beautiful were a rack and two amp platforms by NY's own Box Furniture, out of Brooklyn.
