i, too, have contriva diacera se speakers and if you are in the mid atlantic part of the usa i would suggest you come to the Capital Audio Fest in the d/c-maryland area in july and hear them with the Chalice Audio 'Grail' SET amps....if your budget allows they are better...to my ears then the Ypsilon amps..have not heard the Dartzeel's but would put the 'Grails' up against any amp with the tidal's..just a thought. or if you are near virginia you are more then welcome to come and spend a day or so and listen to my set-up...
