You may have already seen this if you are researching the 383, but there is a review at www.soundstage.com. They loved it, and gave it a Reviewer's Choice Award. I also remember reading about it in Stereophile, which also gave it a great review. Based on the reviews, and comments from actual owners, it seems to be a serious instrument with serious sound.
For integrateds in this price range, I would also be looking at the Rowland Concentra II, or maybe the new MAC MA6900.
