A prominent Los Angeles engineer said 'The best way to describe the sound with the tube circuit involved is you start with an SF-24, add amazing midrange reach and transparency, sprinkle fairy dust all over it, and you get an SF-24V.' It's not the most technical explanation, but it does the job!
Grammy winning scoring engineer Alan Meyerson (Angels & Demons, The Dark Knight, Pirates of the Caribbean) says 'The latest addition to Royer's tube ribbons, the SF-24V stereo, is astonishing. Unbelievable sound - superb imaging! Royer has hit another home run with the SF-24V.'
