After listening to many speakers i will buy the Epos K2. But i'm in dubt which amp. For my music, metall and rock on normal listening niveau, i think NAD C356BEE could be the best. Otherwise; Creek Evo 50A always been tested with Epos (K2) and maybe the best match. But i' m aftraid the bass is not so good and the sound and highes are not so sweet as the NAD. What do you think?
