Apollon Ultima is a power amplifier in monoblock configuration. It’s design is a double push-pull implementing 4 power tubes per monoblock.

All electronic components are through hole type soldered by hand.

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

Apollon Ultima implements a dual push-pull configuration for each channel allowing it to draw large amounts of power from the power tubes. So Apollon Ultima can drive easily power hungry loudspeakers. Gold plated RCA and XLR connectors are implemented for the signal input and WBT-0710 Next Gen binding posts for the loudspeakers. The XLR balanced input is pseudo balanced. True balanced XLR input can be provided upon request.

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 power resistors and Mundorf Supreme silver gold oil signal capacitors are used in Apollon 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.
