Best Pre-amp under 7k

I am looking for a new preamp to fit my system: Theta miles CD, Pass Aleph 3, Proac 2.5, basis 1400 with graham 2.0 and grado reference. I have an audio research PH3SE as my phono stage so I dont need one. Have been looking at Rowland Synergy, Levinson 380S, Hovland, Thor and Audio Research LS25. I enjoy the liquid sound of tubes but highly regard the detail and bass slam from solid state (i.e. Levinson gear). What is the best preamp for my sytem to provide me with detail, superb imaging, tight bass, and a smooth sound? If I have to choose between detail/superb imaging and liquid sound, I would go with the detail/imaging. Thanks for any help in this mind-bending saga!!
