MZ PRE 3 + SWAF

Linear Tube Audio is proud to introduce

MicroZOTL Preamplifier the Third

Our Level 3 preamplifier represents a generational shift from its predecessors.

We took what we learned from Preamp Level 2, added lessons from Velo and Aero, and decided that the only way to truly move forward in performance would be to entirely redesign the layout of the audio circuit.

By combining several circuit boards we significantly shortened the signal path and reduced the number of interconnections, which removed opportunities for noise to enter the circuit. A larger board also gave us enough room to use the best quality components and optimize their placement. Improvements to the grounding scheme resulted in our quietest preamplifier yet. 

Building on what we’ve learned with the Velo and Aero, we have fully reworked the power stage in the preamp to decrease noise and increase output capability. Shared sections of the circuit have been separated to give isolated, dedicated power to each output channel. The total power storage increased by 70%, with significantly more of that providing instantaneous power delivery right next to the parts that need it.

We improved the ZOTL stage by redesigning our custom components and utilizing surface-mount parts in critical areas to get higher performance and reduced parasitics.

We’ve also added a high voltage delay and a soft-start filament circuit to warm up the tubes more gently.

AND, after doing all of that, we kept the tubes in the same place so that we can continue to offer an upgrade path to existing MZ Pre owners. 

The MicroZOTL Preamplifier Level 3 is available to order now.

Pricing
MicroZOTL Preamplifier Level 3 $5,950
Upgrade to Level 3: $1,950

Come visit us in Dallas!

We'll be at Southwest Audio Fest this weekend, March 21-23.
Hear the new MZ Pre 3 in Room 1201 with Sound Lab Speakers and Dr. Vinyl.
We're also in:
Room 1105 with Rizzi Acoustics

David Berning inducted into The Absolute Sound's High-end Audio Hall of Fame

We are thrilled to announce that David Berning has been inducted into The Absolute Sound’s High-End Audio Hall of Fame for his five decades of innovations in audio technology.

David’s invention of the ZOTL architecture revolutionized tube amplifier performance. His contributions continue to inspire audiophiles and professionals alike, solidifying David’s legacy as one of the foremost amplifier designers in the world.

It is an honor and a privilege to get to work with such a great audio mind, and we are pleased to congratulate David on this honor.

Aero is now Roon Tested

LTA is excited to announce that the Aero DAC has received Roon Tested Certification from Roon.

Being Roon Tested means that LTA and Roon have collaborated to ensure you have the best experience using Roon software and LTA equipment together, so you can just enjoy the music.

In practical terms, this means that when you enable the Aero in Roon, all the settings will be properly configured automatically for easy plug-n-play use.

On the fun side, when using the Aero in Roon, a custom image of the Aero will be displayed in the Signal path and other areas of the Roon interface.

More about Roon

Roon is a revolutionary music player that transforms the way you explore and expand your music collection, as you listen on all your gear. 

Roon combines your files and streamed music into one vast, interconnected digital library, inviting you on new and immersive journeys of musical discovery - every time you jump in. 

It works flawlessly on thousands of Roon Ready, AirPlay, Chromecast, and USB devices - and Roon ARC gives you the freedom to listen absolutely anywhere.

More about the Roon Tested Program

Roon’s fundamental goal is to provide a consistently stellar user experience. This goal doesn’t stop at the software... the experience extends all the way down to the audio playback hardware, regardless of manufacturer.

As a Roon Tested partner, LTA has provided equipment to Roon for testing with a variety of different operating systems and computers, and shared information about its design and capabilities.

We have a direct relationship with Roon, and the Roon support team has our devices on hand, so you can confidently choose to use LTA hardware with Roon.

David Berning's Cycling Passion

David on ride-marshal duty at Lymphoma charity ride

You may know David Berning as an innovative hifi amplifier designer who developed the technology behind all of Linear Tube Audio’s products, but David is just as passionate about cycling. He has ridden over 375,000 miles - a distance that could take him to the moon and back, with just 65,000 miles remaining. For long periods, David has gone without owning a car, relying solely on his bicycle.

Among many other long-distance endurance cycling feats over the years, David has qualified for and completed multiple Paris-Brest-Paris rides, the oldest continuously run cycling event in the world and the grandfather of randonneuring. In 1987, he completed the grueling 750-mile ride in an impressive 77.5 hours, stopping only to sleep after 38 hours and for fog at mile 650.

Combining Passions: Cycling and Electronics

David has also found ingenious ways to combine his two passions of electronics and cycling. On a visit to David’s house in 2022, he showed off a DIY build of a human-powered TV, DVD player and headphone amp. He designed and built the gearing setup and all the electronics - even the bicycle stand is custom made. The setup thoughtfully includes a fan, also powered by the rider. The faster you go, the more cooling wind you get!

Cycling-Inspired Product Names

All that to say, David loves cycling very much. So, when we were developing our latest products and kicking around name ideas, honoring David’s passion for cycling was an idea that quickly gained traction. We compiled a list of cycling-related terms and chose two we thought were appropriate for our new headphone amp / preamp (Velo) and DAC (Aero):

- Velo: French for "bicycle"

- Aero: Short for "aerodynamic," denoting design or form optimized to reduce air resistance and drag

We are proud to use cycling-inspired product names to pay homage to David Berning's remarkable achievements and lifelong devotion to the sport of cycling.

Z10e makes Sterephile Magazine's 2023 Recommended Component List

For the fourth consecutive year, Linear Tube Audio’s Z10e headphone amp + integrated amp has been selected for Stereophile Magazine’s Recommended Components list.

The Z10e landed in two separate categories: Integrated Amplifiers and Headphone Amplifiers.

It’s only one of two amplifiers to be honored in two categories.

The Z10e is the only amp in the world that can power electrostatic headphones, traditional dynamic headphones, and speakers. If only there was an “electrostatic headphone amp” category…

Here are some excerpts from the listing:

The Z10e got the best from Abyss AB-1266 Phi TC, Focal Clear, and ZMF Vérité Closed dynamic headphones and excelled with STAX SR-009S and Dan Clark Voce electrostatics.

“The LTA Z10e/Susvara combo missed no beats, showed no weaknesses, and kept my head bopping...The Z10e amp displayed no hesitations, dullness, or clipping; no smoke from the tires, no engine stalling—only full-traction, high-torque engagement.”

With the Audeze CRBN headphones, the Z10e's "overall, timbre and tone were just right and satisfyingly color-saturated."

AXPONA 2022: Worth the Wait!

The last time the hifi audio world converged on the suburbs of Chicago for AXPONA, the largest audio show in North America, was 2019. The ensuing three years was the longest decade any of us had ever experienced, so we were excited (and a bit wary, admittedly) to see old friends and meet new ones at AXPONA 2022 last month.

Friends, I’m here to tell you, it was worth the wait. Smiles and good cheer - and good music - were plentiful.

LTA featured in two rooms:

Room 606

Room 696

We were also in the headphone and personal-audio focused EarGear Expo, featuring:

Response was off the charts! Here’s what the audiophile press had to say:

Thanks to everyone who came to our rooms and our EarGear booth!

Thanks to our wonderful partners!

Thanks to the staff at the hotel (tip your housekeeping staff), the shipping company, and the Axpona event team.

Thanks to literally everyone at LTA who contributed to making this show a success.

See you next year! (Hopefully!)

Jazz Guitarists Bill Frisell & Julian Lage Love the LTA MZ3

We first met jazz greats Bill Frisell and Julian Lage in NYC at a private preview of the Audeze CRBN and LCD-5 headphones in the summer of 2021. Audeze had chosen LTA amps - the Z10e and MZ3 - to showcase their latest flagship headphones to the invited group of luminaries from the world of music, audio production, and hifi. This group included Frisell and Lage as well as Ron St. Germain, Nate Wood, Chris Lightcap, Herb Reichert, Steve Guttenberg, and many others.

So, in a strange and wonderful twist, we were in the room with some of the greatest musicians alive, but instead of us listening to what they make (music), they were listening to what we make (amps)! It was quite a thrill, to put it mildly.

After the Mutual Admiration Society meeting had ended, it was decided that both Frisell and Lage needed to own an MZ3 to go with their Audeze headphones. A couple months later, after spending time with their new LTA-powered hifi setups, Bill and Julian were kind enough to share their thoughts on how the MZ3 changed their relationship with recorded music…

“When I was a little kid I got my own transistor radio. I loved it. Went with me everywhere. Slept with it under my pillow at night. Wow. The joy and thrill of hearing new music for the very first time. Being transported into another world. Mind blown. That is the place where I want to be. I long for it. Listening now to Audeze LCD5 headphones through a Linear Tube Audio MZ3 amplifier brings me right back to those wonderful moments. Mind blown. I’m so lucky. Thankful.”
— Bill Frisell
“The MZ3 combines power and richness in a way that is so deeply musical and pleasurable. Listening to music through the MZ3 makes me feel like all of the acoustic and sonic information available is being focused like a beam of light, stripping away anything that might color or impeded the purest signal. The MZ3 makes it feeel as though I’ve been ushered into the center of the music and the musicians making it. It is utterly sublime! A dream!”
— Julain Lage
