Theseus Ultima amplifier is an Integrated amplifier with 3 line inputs a phono input and a USB DAC input. It’s design is a single ended class A capable of utilizing many types of pentode power tubes power tubes (from EL34 to KT170) and dual-mono power supply.
All electronic components are through hole type silver soldered by hand.
Theseus Ultima amplifier utilizes our top of the line 8 layer handmade output transformers with high quality core for superior sound quality.

A class A integrated tube amplifier which gives a superior sound quality foe pure audio lovers. As a class A amplifier Theseus Ultima requires high sensitivity loudspeakers to unfold its virtues.
Theseus Ultima provides an MM tube phono stage, three line inputs and a USB DAC.
Gold plated RCA connectors are implemented for the signal inputs/output and high quality binding posts for the loudspeakers. For the volume control the classic blue Alps is used.
An elegant remote control in aluminum case offers you control over all the functions of Theseus Ultima integrated amplifier. Volume control, input selection and mute.

Carefully selected values and types of the electronic components contribute to the reliable circuits operation and the high sound quality of the amplifier. Metal film resistors and premium quality oil capacitors (Mundorf Supreme Silver Gold Oil – Rike Ausdio QCap4 Copper Oil) on the signal path are used in Theseus Ultima. Along with the premium quality tubes Theseus Ultima achives a high-end sound quality.

The meticulous PCB design ensures excellent behavior in SNR, distortion and channel separation. Inner signal wiring with high quality shielded signal cable. Power wiring uses high quality copper cables of more-than-needed AWG gauge, to achieve low impedance power transfer. All power cables are twisted in pairs to minimize the electromagnetic interference.

The handmade 8 layer output transformers with high quality copper wire and core material enable the amplifier to reveal an excellent sound stage and the slightest music details through the entire audio spectrum to give you a unique audio experience
Made by us and tested thoroughly for quality and reliability.
The same applies to the power transformer and the chokes.
The positioning of the transformers and chokes is such that minimizes the magnetic coupling between power and output transformers.
