After reading John Marks' review of the Leben CS600 in the June 2010 issue of Stereophile, it reminded me of past Stereophile mentions of Leben integrated amplifiers at various Hi-Fi shows, so I thought I'd post them so you could go check them out.
The first one is Robert Deutsch's mention of the Leben CS600 integrated amplifier at the the 2008 Montreal show on the Stereophile website here.
As soon as I round up the rest of the links I'll post them too - enjoy!
