Plinius (8200/9200) or Mcintsosh (6500) may be what you are looking for. Both have decent phono and HT bypass. May give up a little speed/slam to the Krell, but fits your description.
For less money, Jungson and Consonance also make excellent solid-state or hybrid integrateds- but don't have as many features as Plinius or Mcintosh.
There are a lot decent tube integrateds out there (Antique Sound Labs, Primaluna, Jolida, Rogue, etc)- that may or may not work with your speakers. Also, tubes may give you a larger soundstage, but are not necessarily smoother or less bright than good solid-state, especially at higher volumes.
