Need help matching DAC to speakers and amp

I have purchased a Bryston B100 integrated amp and B&W PM1 speakers (and JL sub). From what I have read about the Bryston, it is very true to form, not warm and not analytical. I have also listened to the B&W's and they are along the same lines, great detail, not warm. I think as I look to pair them with a DAC, I would like to get something that is on the warm side. Any suggestions?
