The usual problem that you run into is that most DAC/CD players have **way** too much output. The result is that you can usually clip the amp at volume settings well below maximum from the digital source- which will cause *serious* loss of resolution.
As a result, you often get better results with an active line stage. I advise that you try direct for a while; if you can keep the volume control over about 85% of full volume you will probably be OK.
