I am buying one amplifier to my sonus faber guarniere, but I have one doubt, is possible to use one krell fpb600 with this speakers??, they are bookself and have 86 db sensitivity, I live more than 2500kms from the dealer, so I can not hear this combinations( I live in a distan Braziian city), I am afraid that the 600watts from krell can be a danger to my speakers, I do not have a lot of options, is to buy one gamut d200 mk3 or this krell, I read one person in the audioreview site ,that he used the guarniers with krellfpb600, and the sound was good, but I could not send a email to him, I do not hear music loud, so I am asking hellp becasue I have only 72 hurs to buy one of this. Thanks a lot for hellp me.
