Kora is a French brand in Toulouse (Hi End Audio Technology) which only the high-end HiFi.
This little amp Hybrid is part of the input range and delivers a high quality.
Good bass and silky midrange desire and good treble. I do not find it lacking particulier.Les first 15 watts in Class A. The preamp circuit is based on a tube-EB 6NP1 already gave good results, but I replaced it with a ECC188 which I think is best. As for power it is based on Mosfet transistors. Can be used as a preamp or power amp circuits as possible to deal separately with the connections and Direct Direct Out and In and In and Out Monitor as "Direct" button and the "Monitor" on the front. I use it every day on KEF900 pregnant and I am very happy. The Musician and Audiophile I am recommend it without any trouble.
