The Shelter 901 might be substantially better than the 501 for a couple hundred more, or so I've heard. Maybe TWL could shed some light on this.
Ben- I, too, am surprised that you found the Benz a little lean. Most find Benz skewed strongly toward warm. Perhaps you are trying to describe some other performance aspect that you are trying to address? Maybe you are looking for more/less/different low frequency? Your penultimate sentence suggests that you find the Benz to be "dark sounding", which conflicts with "lean"- perhaps you could clarify what you are looking for?
