TAKE YOUR LISTENING EXPERIENCE TO INFINITY.

We build and sell custom high quality tube audio amplifiers. If you are looking to dramatically improve your listening experience, you will find that Z-Infinity amplifiers deliver the highest quality audio reproduction. All of our amplifiers are based on simple, proven designs, and are hand-assembled using highest quality components.

Our mission is: producing the highest quality sound imaginable. All of our vacuum tube amplifiers are designed with this goal in mind. "As simple as possible, but no simpler" is a key design principle we utilize in all of our products. Designs such as constant phase circuits, no or simple feedback, 100% tube audio path - all add up to better linearity and ultimatelly better sound quality. Your music comes alive thanks to the pure linear amplification of vacuum tubes. We know that putting a number on sound quality is impossible. That is why we have many customization options for different tonality characteristics to meet the needs of the most demanding listener.

If you are particular about your sound, we design and build custom tube amps tailored exactly to your specifications. Take a look in our custom products section to find out more.

Why Tube Audio?
There are many opinions in the audio community about what type of amplifier makes the best sound. Many professional musicians, audio experts and enthusiasts prefer tube amps over transistor amps. We use a 100% tube circuit in the audio path to ensure that the audio signal quality is the absolute highest.

Z-Infinity Output Power
We always list true RMS power, rather than peak-to-peak or other, often theoretical, high power rating. We overdesign the power supply of every one of our amps to provide ample headroom for the highest dynamic range of audio possible. All Z-Infinity amplifiers, accurately reproduce powerful peaks in the audio signal, often at multiples of the RMS power rating, while other amplifiers simply clip.

If you have any questions, we are here to help, feel free to contact us at anytime.

Stereophile Review by Art Dudley 
"The Z-Infinity Z40, which provided even more gain than my Shindo
Corton-Charlemagne monoblocks, also offered a generous measure of the more
expensive amps' good tone and texture, with a deep, tight foundation in the
lowermost octaves. Alan Spenner's electric bass in "My Only Love," from Roxy
Music's Flesh and Blood (LP, Atco SD 32-102), was solid and tuneful, while
Andy Mackay's saxophone was perfectly reedy and colorful. Great texture and
tone endured throughout other recordings. Strings, woodwinds, and harp were
appropriately sweet through the Z-Infinity with Rafael Kubelik and the
Vienna Philharmonic's recording of Smetana's Má vlast (LP, Decca/Speakers
Corner SXL-2064/5), as were the various acoustic instruments used throughout
Andrew Bird's Noble Beast (AIFF rip from CD, Fat Possum FP1124)." - Art Dudley, Stereophile
