The Ultimate Headphone Amplifier
Experience the next level of audio performance with the Ultima 88,
an amplifier designed for audiophiles who crave a dynamic sound signature.
Powered by KT88 tubes, the Ultima 88 delivers ample power to drive any
headphones, offering a distinctly different sound profile from its older sibling,
the Headonia 300B.

The Ultima 88 utilizes KT88 tubes in the output stage, providing a powerful
and dynamic audio experience that is perfect for those who enjoy a more
energetic sound.

Just like the Headonia 300B, the Ultima 88 includes an impedance selector
switch. This feature ensures optimal performance and sound quality across a
range of headphones with impedances from 32 to 600 Ohms.

- Crafted with the same meticulous attention to detail as the Headonia 300B,
the Ultima 88 features a sturdy chassis made from milled aluminum,
minimizing interference and vibrations to deliver pristine audio. - High-Quality Components
The Ultima 88 is equipped with top-tier components, including precision
Japanese Alps potentiometers, German-made Mundorf capacitors,
and Lundahl transformers on balanced inputs for enhanced sound quality.

The output transformers are hand-wound in-house with high-quality copper
wire sourced from Serbia, ensuring exceptional sound
quality tailored to your headphones.
- Balanced and Single-Ended Inputs
Offering both balanced and single-ended inputs, the Ultima 88 provides
flexibility for connecting various audio sources, ensuring optimal signal
integrity and noise rejection. - Versatile Connectivity
The Ultima 88 features a preamp output for connecting to external power
amplifiers or speakers, along with both 6.3mm and 4-pin XLR headphone
outputs for versatile headphone connections. - Stunning Design
With a sleek and timeless design, the Ultima 88 is not only a
high-performance amplifier but also an elegant addition to any audio setup.
