I recently got a sansui au-9500 from my bro.. upon surfing the net i found that the au-8500 has a much bigger value on its caps. the higher model au-9500 has a 4,700uf x4 while the lower model au-8500 house a much bigger value with 15,000uf x2. what are the pros and con regarding this amp design? and more listenable to sansui fanatics...thanks for any comments regarding my query..
