Kiwanoron,
I listened to the V.5 Studio 60's just a few weeks ago and liked them very much...and of course the new look / cabinet design is quite nice as well. They have a nice detail and focus to their sound, without being to bright, and a wide sound-stage. Not that words can get at all of what one hears, but that is the generally impression I got without doing alot more and varied listening to the speakers.
As for the 60's over the 100's I think that really depends on the room size, your listening habbits (i.e. how loud do you like it?), and your subwoofer. In my case I know that the 60's would be plenty with a PB13, but in a larger room with higher listening levels the 100's would be desirable. This comes down more to personal preference....
Either way you will be most happy with these speakers...
