I finally settled with Jeff Rowland Concerto Integrated, Audioquest Sky 1m 72VDBS, Audioquest Volcano 72VDBS, Audioquest NRG-5, Weiss DAC2, Fisch Audiotechnik AC passive filter, Aavik rack with Nordost Pulsar Points. I couldn't be any happier. Maybe it's just my taste but I recommend to anybody else with Be-718 looking for an amp to at least make an audition with the JR.
