Ayon Stratos DAC – Vacuum Tube DAC – Pre-Amp Volume Control

Manufactured in Austria, Wow – 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 Stratos vacuum tube DAC Preamp will amaze and stun you. The soundstage is so realistic to the live event, the Stratos is so good, that your speakers will disappear during playback. Wall to wall three dimensional performance!

The Stratos can do it all – computer playback DSD professional audio use. The Quad differential gain stage, composed of 2x 6H30 dual triodes per channel a total of 4 6H30’s are so liquid, you will find yourself fully captivated and engaged.

Also 4x 6Z4 tubes for the power supply and signal rectification. Amazing! The Stratos DAC HD high capacity power supply setup in a “bridge” rectification design, is genius.

The Stratos will prove to be an intricate component, a must have machine in your system.
