Ialmoust have 9 years ago, and there was no problem at all ... work as the first day I bought it. Because it is not the price, are really worth! Sony has always been a great product! I recommend them;). I have a Pioneer stereo receiver model SX-5560 Black (no money SX-750) for 9 years (but the model was introduced in 1976 and manufactured until 1977) and was 34 years ago) and I am totally satisfied, Pioneer works perfectly and has excellent performanceMade in Japan. I like:) ... Pioneer product offers a level of performance that can only be described as ~ A ~ W ~ E ~ S ~ O ~ M ~ ~ E ... If someone has a brand that you like or are looking to buy here until after I'm glad you like. Surround speakers are not as impressive Very, but it really works to music with surround Sony Thay have a good team ... but Sony does everything and just put the icing on the cake very''... It is important that I am pleased with them).FEET ...
