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.

Tube Amp Output Power
We always list true RMS power, rather than peak-to-peak or other, often theoretical, high power rating. Another factor is the extended headroom in our amplifiers due to many factors such as a high wattage power supply. HDR Audio, a characteristic of all Z-Infinity amplifiers, accurately reproduces powerful peaks in the audio signal, often at multiples of the RMS power rating, while other amplifiers simply clip. You will be amazed how powerful one of our two channel 100 Watt RMS tube amps sound!
