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

Look for a pre-owned pair of Rogue M150/M120 or Quicksilver V4.

You will no longer need a fire extinguisher either.
I second Audiofeil's suggestion on the Quicksilver V4, and will add the suggestion of the Wolcott P220 monos. Both well within your budget expectations if you go with pre-owned.
Hi Audiofeil, do you think that the sound of the Rogue is as musical as the ASL? I have read that some people can found they a little thick. I like the sonic flavor of the Hurricanes and don't want something more lush or romantic....

In respect to the Quicksilver I'm looking for something with more power on triode. My ASL have 100W on triode and 200W in pentode, .......

Another brand that can I consider is Atma-Sphere. I don´t know the lowest impedance of the highs of my speakers and it seems that this can be an issue. I´m from Spain and near here I have found a pair of Atmas-Sphere Ma 1.5 MKI (from 1998)...
