We build the world's finest audio components TM

The VAC Phi Alpha Series represents more affordable embodiments of our finest audio circuits and parts. As such, they might be considered to offer the greatest value, yielding most of the result at the most reasonable price possible.
The VAC Phi Alpha D/A Converter is designed to extract all of the nuance possible from CD's and USB sources. It features an I/V conversion circuit that is free from the hysterisis and phase smearing effects common to conventional circuits, resulting in a more natural, organic presentation. The all tube analogue stage (no op amps!) offers balanced and single-ended outputs, and you may engage a volume control if desired. Two inputs support S/PDIF coax (optional AES-EBU), while the third is a high quality portal for USB computer/music server sources.
External power supply, of course.
