Reference Amplifier

Class AB1 2x100W

Reference amplifier is an Integrated amplifier with a built-in Bluetooth v5.0 receiver, 3 Single ended inputs, 1 XLR balanced input, 1 Tape output, 1 Pre output and a master loop.
It’s design is a push-pull configuration implementing 2 power tubes per channel in class AB1 operation self-biasing and dual-mono power supply.

All electronic components are through hole type of the highest quality silver soldered by hand.

Reference amplifier utilizes our top of the line 16 layer handmade output transformers with high quality copper wire and core material for superior sound quality.

Utilizing two KT170 tubes, Reference amplifier can deliver up to 100W of power per channel, allowing it to drive any loudspeaker efficiently. Very high quality electronic components are implemented to achieve superior high-end sound quality. Low tolerance, high frequency, non-inductive, ultra low noise resistors are used in all stages. Mundorf Supreme Silver Gold Oil capacitors are used for the signal. Self biasing configuration with chassis mount non-inductive low tolerance heatsink resistors. Premium quality signal tubes.
Gold plated RCA and XLR connectors for the inputs/outputs. WBT-0710 Next Gen loudspeaker binding posts.

An elegant remote control in aluminum case offers you control over all the functions of Reference integrated amplifier. Volume control, input selection, mute, LED illumination level and stand by mode.

Reference amplifier provides a high quality Bluetooth audio input to stream your favorite music from your smartphone. A balanced input and three single ended line inputs.

A master loop allows you to connect an external circuit such as room correction, equalizer etc. For the volume control the classic blue Alps is utilized.

All stages are on separate PCBs to achieve maximum isolation.

The PCB design offers very high SNR, low distortion and high channel separation. All electronics are in a separate compartment, shielded from the power transformer. Also the output transformers are in their own separate shielded compartment as is and the power transformer. All these contribute to the unique appearance of Reference integrated amplifier.

Reference amplifier is equipped with a surveillance circuit which monitors the current of each power tube. If a problem is spotted with any tube, the amplifier will not start and the status LED in the front panel will blink red accordingly with the faulty tube. In this way no damage can be caused to the amplifier by a malfunctioning tube and will show you which tube to replace.

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 high-end 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.
