Hello,
i just purchased this used, sony integrated amplifier,and i love it. it sounds great, it pushes my mtx tower speakers nicely. i just have a question on a button labeled "DBFB" located on the right lower corner of the face plate. what is it for?, what does it do?..any feed-back, or information would greatly be appreciated.
