Sensational sound signature (American Sound), very forgiving to low fi sources. Probably the smartest compromise between savings and quality feel ever made (whole line). Fluoroscan tube keeps colour saturation and runs forever. Not the best spec out there, but more than enough especially knowing that Pioneer has almost certainly underrated given specs for the model. Truly pleasant to listen to, sturdy and with some quality components, if not abused should run flawlesly for another decade, yet recap strogly recommended as SA 508/5800 topology would benefit from upgrading capacitors.
