I have auditioned both side by side, w/same system setup. The 1.5's lack any low freq resp. The 2.3's(I now own) are better balance and synergy all the way down to 32hz or so. Make sure you get the updated drivers, if you purchase an older pair of 2.3's.
I even like the 2.3's better than 3.5 or 3.6's. Remember Thiel speakers require great componets.
Good Luck
