can the VA Beethoven Baby Grands ROCK?


hello, I've recently auditioned the Vienna Acoustics Beethoven Baby Grands and absolutely loved them. unfortunately I didn't have enough time to check out all kinds of music I listen to.
hooked up to my Krell 300i they sounded fantastic playing the likes of David Bowie, Mark Knopfler, Pink Floyd or even some RHCP. smooth and yet dynamic with zero listening fatigue.
I'm wondering though... can they really rock? I mean I still have hundreds of CDs from my younger years - lots of hard rock, some really heavy stuff, Slayer and such. I usually don't listen to them at home but once in a while... :-)
I've come across many opinions that the Viennas are too laid back and "polite" to rock and roll. Forgiving of poor recordings but lacking expression. I'd love to hear some opinions from VA users who listen to rock music.

thanks for the input. I'll go audition the Viennas once more. In the meantime I've had a chance to hear the Dynaudio Special 25 monitors and WOW! pretty good dynamics and bass extension for such a small speaker!
Special 25s are very special - need good amplification (high current) for them though.
Larry is right.

If you want to ROCK, you need to move a lot of air, and you need to extend down low. 6" bass drivers need not apply.

Vienna Acoustics will do a good job at making the majority of your collection sound palatable, but you will obscure details that a more transparent speaker will expose.

The special 25 on the other hand - That is a pair of monitors that can rock.

Though - there's still more potential out there with even bigger speakers! Contour 5.4 perhaps?
