Ayon Sigma DAC – Vacuum Tube DAC – Volume Control
Finest, award winning, Vacuum Tube DAC – at ANY Price!

Manufactured in Austria, based on the Ayon Stealth DAC platform, the Sigma is an excellent performer. The Sigma is a reference quality DAC, Pre-amplifier.
We hate to sound like a broken record, but the Ayon gear qualifies by the following statement: Ayon Audio has really outdone themselves again! Every time a new model is released, which is about every 4 to 5 years, we think to ourselves – will the new model be even better.
I have to confess we do that here at USA Tube Audio and I can confirm that every time Ayon Audio introduces a new model, we are stunned that Ayon can yet squeeze out a superior performance over their Legacy model being replaced.
Ayon has done it again. The Sigma vacuum tube DAC will amaze and stun you. The soundstage is so realistic to the live event, the Sigma is so good, that your speakers will disappear during playback. Wall to wall three dimensional performance!
The Sigma can do it all – computer playback DSD professional audio use. 1x 6H30 dual triodes per channel. The 6H30’s are so liquid, you will find yourself fully captivated and engaged.
The Sigma will prove to be an intricate component, a must have machine in your system.
