The 383 and the JRDG are, certainly great integrateds. I, however, liked the YBA Passion Integre better than both. It killed the Levinson, and the sweetness and tubelike qualities couldn't be matched by the Concentra. The $ is right and the quality is incredible. Now is the time, before Sam Tellig's review comes out. Then, everybody and their mother will want one. It's definitely worth a listen.
