NAGRA is at Montreux Jazz Festival. They play analog tapes from the Montreux Jazz Festival and their collection. They are played on a Nagra IV -S via an HD PREAMP and two pairs of HD AMP.
The Stenheim speakers in the photos are the Reference Ultime Three in a special piano lacquer/chrome gold edition. “Special thanks to Claude Nobs Foundation for the tapes and to EPFL Montreux Jazz Digital Project for computing those treasures.”
