Krell Resolution 2 - suitable upgrade??

I have budgeted about 15K for a suitable replacement. To then end I am searching for suggestions, especially from those who have heard the Krells. I have auditioned Sonus Faber Cremona M's. Very nice sound, very musical however not enough of a difference to replace the Krell's. Music I use to audition is: Michael Hedges any track , TELARC Aaron Copeland Fanfare for the Common Man, Sheffield Lab Pressure Cooker, and Dianne Reeves.
Thanks!! - HP
