Prima Luna three or Adcom GDP-750?

I am looking for a preamp on a budget at around 850 or so. I need one that fits well with my system. Current amp is AES Six Pac mono, DAC MF Tri Vista. The Prima has gotten some very good review but I am afraid combined with a tube amp, the overall sound might be too tubey. I'd like to have an overall sound that somewhat accurate but not too much detail that will detract from the music.
