100W+ solid-state amps known for beautiful mids

Quad 909 back in the day had a reputation for the best mids running up to $5000. I've used it in the past and I would definitely say that the mids were the highlight on that amp. It wasn't overly coloured, a hint of warmth, but it had a purity and sweetness to its mids. Unfortunately, mostly everything else was okay at best, kind of rolled off at both ends and congested stage-wise.

I'm looking for that same purity and sweetness without sacrificing the rest of the sonic traits. What have been your guys' contenders for 100W+ solid state power amps with the best mids?
