Achilles Ultima is a power amplifier in monoblock configuration. It’s design is a class A 300B triode amplifier with mu-stage driving circuit. All electronic components are through hole type silver soldered by hand.

Achilles Ultima utilizes our top of the line 16 layer handmade output transformers with high quality core for superior sound quality.

The 8W of power per channel of Achilles requires high sensitivity loudspeakers to enjoy your music. The triode class A configuration of the 300B with the high linearity of the preamplification stage offer an unsurpassed audio experience to every audiophile.

Gold plated RCA connectors are implemented for the signal input and WBT-710 Next Gen binding posts for the loudspeakers. Carefully selected values and types of the electronic components contribute to the reliable circuits operation and the high sound quality of the amplifier. Mundorf Evo signal capacitors and premium quality tubes are used in Achilles Ultima.

The meticulous PCB design ensures excellent behavior in SNR and distortion.

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 16 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. The positioning of the transformers is such that minimizes the magnetic coupling between power and output transformers.
