AVID Sigsum Integrated Amplifier

The Sigsum Integrated Amplifier is a logical development of our cascading product design.
In all our designs, we are driven by sound quality and an uncompromising approach to offer the best in the category.

Sigsum shares many of the extremely high-specification components found in our Reference electronics, every attribute to the highest order.
Within an integrated amplifier, there are four main building blocks; power supply, pre-amplifier topology, power amplifier and volume control.
Like a jigsaw puzzle, every part needs to be perfect and then fit together perfectly, the weakest part letting everything down.

In our obsession to offer the best, we have not fallen short on any of these building blocks that make up this integrated amplifier.
Power Supply; massive 1.1KVA mains transformer and large capacitors give prodigious reserves and the sound has slam and low-frequency control.
Pre-amplifier topology; bespoke circuit design and components allowing faithful reproduction with limitless headroom.
Power amplifier; directly scaled down reference power amplifier with the ability to drive all loudspeakers comfortably.
Volume control; retaining possibly the world’s best control, the ALPS RK50 allows you to hear every detail with such life and realism.

And not forgetting our vinyl roots the built-in phono stage is the same as our award-winning Pulsus phono stage.
A passive RIAA (with Neumann HF correction) circuit using high-end capacitors, helps maintain linearity of reproduction and its own 35va mains transformer giving independent power to each channel. Fully flexible for any cartridge with gain and resistance easily adjustable.

Like all our product's, Sigsum is passionately manufactured within our own facilities, everything from PCB assembly, testing and quality control to the high-quality casework ensures a long-lasting reliable product, allowing you to rediscover your music collection.

In a world of specifications and audio jewellery, the Sigsum is old school passionate design done right.
Just listen, you'll find no fake performance, just the ability to strike fire in the heart and tears of emotion.
