Classe ca 150 vs wyred for sound st250

Hey I am looking for any input from anyone familiar with these amps. I have a chance to buy both. I listened to the Classe with a tubed pre similar to mine. I did like what I heard but didn't have much time. I never had experience with wyred. Any help?
Can't say for the w4s 250, but I owned the st500, and the ca150, and the st500 was much better. More open, clearer, better bass, more articulate without getting hashy. The ca150 wasn't so good. Not bad, but a step down from the Bryston 3bst it replaced, and the w4s is better than that.
