I'm currently researching Aragon 8002 and the new DNA series as well as the 0.5 by McCormack (see my recent posting in "system matching"). AudioReview.com also has several users' comments on both models. Although I haven't listened to McC, opinions from others have me leaning this direction. An audition is forthcoming. You'd certainly want to consider Steve McCormack's revisions but most of them have been incorporated in the new models, according to Mr. M. in a phone conversation I had with him recently. Your speakers and source components may also suggest direction for you. Good luck.
