I would suggest Cairn's own Nanda preamp. I am using that between my Cairn Fog and Cairn Mea monoblocks. The fog is an excellent CDP as well, but if you need CD and DVD playback in one unit, Cairn is working on a 'universal' unit for release nex year. BTW, how do you like your K1's? I can't find anywhere to listen to a pair, but would love to hear them!
