KJ, When I bought my sa11s1, the dealer suggested we change out the two primary fuses. I readily agreed and he took care of it after I had it for a couple of weeks. I could tell the difference right away. I bought my sa7 used and the previous owner had already change out all the fuses. Again, according to him, it made a big difference. All I know is it was one reason I bought his player in stead of somebody else's. I've never regretted that purchase either. There are a myriad of companies you could go to for fuses. Its really your call.
