If you can live with the GAT's single ended RCA connections, I vote GAT. I've looked at and owned other preamps but have always been the happiest with my GAT. Great 3D and layering with an ever so slightly sweet top end with great width and height. I love it. Also, only two tubes to replace and relatively inexpensive to re-tube. At the prices for the used GATs right now, I think they are a bargain.
