Ayre QA-9
The QA-9 Analog-to-Digital converter is our gift to the world of recording and audio engineering.
Designed around a discrete, fully balanced, zero-feedback analog circuit, with our signature variable gain stage, the QA-9 Pro will unlock the soundstage, fidelity and tonal balance in your recordings that you have heard in your head for years.
With the Arda AT1201 at the heart of the digital conversion process, you will become immersed in the music like never before. Astonishing dynamic range, and time, phase, and frequency accuracy, make the QA-9 Pro the gold standard for recording, mastering, archiving or product development.
