Vitus audio?

I'd appreciate if anyone knows the Volt/Amperes capacity for Vitus and Boulder. Gryphon has twin 1500 kva, the others?

I think the right Boulder for the comparison is 2060.

Thanks guys for the first impressions, the models I'm looking for (and are fair to compare) are the VA SS101 vs Gryphon Antilleon Sign. vs Boulder 1060series. Not the big monoblocks mentioned but their stereo (alas over 85kg) mates.
With Vitus in this category you can even used it as integrated and/or use a tube preamp and make rellevant conclusions or use it for different music genres, even for digital or analog equipment.

The speakers: Amati Anniversario, the room 8x5 sq. meters, Europe.
