I just replaced my 3003 with a 3303 because my 3003 wouldn't get very loud. The 3303 fits in the same spot as the 3003, but does need a new bracket because it has 2 transformers. I got both for about $350 on ebay. It is a good upgrade, and probably better than putting money in the old one. The old speakers also work the the 3303.
