Antique Sound Lab Hurricane: powerful substitutes?


Hello, I have a Duntech Sovereign biamped woth a pair of ASL Hurricane for highs (100W in triode mode). I like very much the sound of the Hurricanes, but i think that the Sovereign would need more power for highs. So I'm looking for a pair of tube monos with more power and for a budget of 4000 $.
I have read good reviews for the VTL MB 450 signature. There is someone that have compared this VTL with the Hurricanes? What other tube monoblocks I should consider?

Thanks

Magnumpi, the Mesa Baron looks nice but here in Spain where I'm, is a non available option.

I have see a pair of Melos 402 gold for sale (400W in triode). Some time ago I owned a Melos 333 Reference preamp and I have a good remember of this brand... This amps are really as good as some comments tell? And reliables?
