Pls recommend preamp for Merlin/Rogue/Wadia setup

Hi, I would be VERY grateful for recommendations for a preamp (and cables if necessary) for the following setup: Wadia 301 CD player, Rogue Magnum M-120 monoblock amps, and Merlin VSMM speakers. I've had these components in the closet for the last 5+ years, before realizing that all I had to do was change the tubes to get it to work again! In the meantime, I've forgotten what little I knew about stereos and stereo equipment. Can anyone recommend a good preamp/cables combo to hook up to this to enable (1) bass adjustment (needs to be increased), (2) running a TV through it, and (3) running an MP3 player through it. I apologize in advance for my ignorance if parts of this question seem stupid, and would be really grateful for some help. Budget is around $1,000, and I am happy to buy used.
