Best Pre-Amp w/Throughput for HT ?

Looking for the best Pre-Amp w/balanced input/outputs so I can have the best of both worlds. Currently own Plinius SA-100 2-Channel Amp, B&W N803's w/HTM-1 Center, Cinepro 3k6II 6-Channel Amp, Lexicon MC-1 HT Processor, Sony DVPS-7700 DVD Player, Wadia 860x CD Player and Speakercraft AIM 3 Acoustical Cieling Speakers for the rear & Side Channels. What I want is the best 2-Channel for music listening and the best HT System with what I currently have. Any suggestions would be welcome and appreciated.
