I just changed from a Grado Reference Sonata to a 103R. I was ready to sacrifice the Grado's lush midrange because I wanted a bit more upper range detail and a bit more bass. The 103R does provide the increased upper and lower ends I was looking for and it does so with engaging musicality. The big surprise was that the 103R's midrange gives very little away in musicality to the Grado! If I had a tonearm that allowed for headshell swaps I would definitely want to have both of these carts and switch between them. For now, though, the 103R is my cart of choice. Good luck.
