Kora Mercury Integrated amplifier, is it worth?

Hi, I noticed that there was very little info on this amp. For the limited info I read, it was not very favourable. Does anyone have any experience? If you choose between Cary SLI-80 F1, Kora Mercury, Jadis Orchestra ref, Musical fidelity Trivista, which one would you choose? They are in similar price range. The Kora amp seems the cheapest of these amps.
