Whatever you decide about an amp, don't sell your preamp. I own one and had an Audio Research SP14 for 12 years before. This is a killer preamp and limits nothing. It is hard to believe that there is any tube preamp out there that is "better". It is a brilliant design, seems to have an incredible soundstage and certainly improved every aspect of my sound.
Keep it. I have just sold my Krell KMA 160, which worked fine, but I wanted tubes so bought a used Atma-sphere MA-2.
