I recently went to radio shack and purchased a pair of Klipsch s3's for $40 because I kept breaking sets of meelectronics m9's. Through my research I have found another set the m2's are very highly regarded and can be had for $50 pre-ordered. Is it worth it to take back the s3's and order the m2's? Or will it make little to no difference? Thanks in advance for your help!
