this is an old posting, but if you're still checking... until recently i used a cal icon mkii (not the powerboss version) with my cj mv55/pv10al combo. my speakers were klipsch kg4. i was very, very happy with the cal. before i bought it, i tested it against the rega planet and a couple of music bank offerings from nak. the cal was smoother, with a better low end. i also beleived it to be more reliable (a buddy has had some troubles with his nak). i've since replaced most of my system, including the cal (in favor of a wadia). i pulled the cal out recently and put it head to head with the wadia. a totally unfair comparison--but, the cal held up just fine. i'd say the icon mkii is still a great machine at a great price.
