i moved from the rds003 to a combination of rqis 1 tours and 1 tour xls. i would recommend the xls just because i think it plays a little closer to the rds003. its a bit lighter than the other one and seems to have a bit more pop. i'd rather use the rqis 1 tours for indoors or hot summer days outdoors and it seems like to me the placement is better with the rqis 1 tour (non-XL version). otherwise, it's mostly the xls for me.
