Pls suggest Amp and other equipment for my streaming set-up.

I converted all my CDs to FLAC files. I want to get a small foot print system but would like to use my existing Wadia 27 DAC and .Totem Mani-2 speakers. (I used to have a pair of Krell 250 Monoblocks, Wadia 270 CD player in addition t Krell KRC 3 Preamp to play my Cds). What equipment would you suggest to get decent audio quality that is better than entry level, for Classical and Jazz? Space (and Money :) ) are the constraints. How do I connect these to play music from the flac files on a hard disk?

Thanks
