Review 
One of my favorite finds of the CES shows were the Opera Consonance single-ended headphone/integrated amplifiers on display. The Cyber 10/30 are KT88/KT66 and 2A3 versions, the Cyber 20/20Basic matching EL84 variants. The fit and finish was high and they sounded seductive and fun to listen to. A pair of added speaker binding posts expands their use beyond dedicated headphone use, making one of these little babies the ideal heart of the ultimate night stand or office system. I was so impressed that I am going to investigate this further and see if I can't get one of those for a 6moons review!
