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! 

Questions for the seller
Dear Sir, I wanted to ask if the headphone amp has any issues. Does it make any tube related noises? Is it silent through the headphones without any music going? Is it possible to easily set the bias for the el84 tubes? what is the warranty period? Thanks,Tom
Hi Tom No it sound pertty increadable yes it is silent with no music and volume turned up it is a self bias amp -- 1 yr parts and labor --90 day tubes Good Listening Stephen Quest For Sound 2307-R Bristol Pike Bensalem Pa 19020 215-953-9099 www.questforsound.com [email protected]
