amp for 87db sophia 3 ?

Hi, could some amp with 60-70 tube watts work with sophia 3 ?
sophia 3 is is more efficient than sophia 2 ? Im familiar with 2.

Thank you.
Yes, It will work. The only question is will it go as loud as you want. If you're a metal fan, try to find an old Krell 300 watter (and don't forget four powered subwoofers).
