Curveball time... :) How about this? This would make your Focal Sopras sing pretty good.

While vintage Levinson amps are stupendous even now, if a buyer does not choose wisely, then one will be out a few thousand bucks to recap/refurbish the amp, but George Meyer, an authorized Levinson repair shop, has already refurb'd this fine amp. Physically, it's in really nice shape too, but it's the sound, the depth, the separation, and the musicality of this amp which is gripping for me. In any case, it's just something for you to ponder, that's all.
