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?

KRELL K-300i is very smooth, detailed, and very powerful. Class A for 90 watts. The CODA #8 Version 1 is not as smooth or powerful but is also a sweet performer. I use both and like them equally.
Thanks for your wonderful suggestions guys, keep 'em coming! 

To maybe help me narrow my search, I'd like to add that a tube preamp is a must in my personal system, and since the majority of tube preamps are single-ended and output-capacitor coupled, I'd like to specify that ideally, the power amp should have high input impedance and have RCA inputs!

For reference, my current system consists of:
Rockna Wavelight R2R DAC
Vacuum Tube Audio SP14 6SN7 linestage
PASS labs X250.5 power Amp
