i never heard the vandy but i have hales rev 3.i'am very happy with them incredible bass and the highs are as natural as you can get in that price range.but you will need power.i read some place that paul hales voiced them with anthem 40 watt tube amp.i used to have a kinergetics kba 75 class a amp it was very sweet but no juice i changed to a aragon 8008 bb and it was as a door had been open the hales sounded twice as big in every aspect and the sweetness was still there.i'am in love with them and would only trade for something far more expensive .
