The Pioneer SX-1280 is a beast and a legend. We went through this one top to bottom, and we believe the end result is finer than anything from the production line. From the preamp to the output boards, everything was recapped. We even loved up the wood cabinet. A receiver of this calibre deserves nothing less, wouldn't you agree?
Note: The very back of the heatsinks are broken off. It doesn't effect the operation and isn't visible from the front. This is why this unit is listed at a discount.
