Lamm+JM Labs

OK. This is a very simple question. Has anybody heard or used JM Labs speakers with Lamm amps and preamps. Right now I have a long term goal of getting some dartZeel in my system. But that does not mean that I wont consider Lamm My speakers are JM Labs 1027Be's. I heard the Dart amp in my system and I was blown away. It just buried my Bryston 4b-ST. If I go dart, it will be their integrated. But if anybody has any experience with JM+Lamm I would really like to hear it.
Thanks
