Does anyone know a company called Viola Labs?
I recently heard their Cadenza/Symphony in combination with Sonus Faber Cremona Auditor and Esoteric P-03/D-03/G-03x making wonderfull sound!
The founders were the engineering core of Mark Levinson Audio Systems in the 1970s and of Cello (Mark Levinson's company after MLAS) in the 1980s. I have not heard them at shows for many years.
Sadly, Tom Colangelo, one of the principle designers and founder, passed away in '07.
