Hi Bolero, I personally own a pair of Vienna Mahlers V1.5. These are wonderful speaker with amazing musicality staging and detail. . . provided they are driven by a high power amplifier with a high damping factor. The newest generation of class D amps has both the control and finesse suited for driving Vienna speakers, as they have often damping factors ranging from 1000 to 4000. I recommend any of the following: latest Spectron Musician 3 stereo or monoblocks, Rowland 312 stereo, Rowland Continuum 500; If you prefer a just slightly cooler presentation, Nuforce Ref 9 SE, Rowland 501.
