I used to have the version I Scorpios. I pushed them with a BATVK300x Integrated with success. I used Stealth MLT Hybrid speaker cables. Nice set up at the time. I went to Focal 1037's from the Scorpios.
I have the Scorpio I and have used them with Art Audio Concerto Plus mono amps. I have heard them with Spectron amplification and it was very good but I prefer tube amps with these speakers. I would think that any good tube integrated amp would be a good match.
