I really need your help! I recently bought an AU-9500, which I'm having a lot of fun, I really was captivated with its sonority, almost pipe! I have connected to it a beautiful Sansui TU-666, because I really like listening to FM. This morning I found a tuner that would best match my AU-9500, it's a TU-7500 for sale here in Brazil. I do not have much space in my house, so I only have what I actually use, I can not accumulate (wife factor). In your opinion is it worth to sell the Sansui TU-666 and buy the TU-7500?
