I recently purchased an older (mid 90s) Harman Kardon amp on ebay. After giving it a thorough cleaning and then rewiring it I am amazed at how good it sounds. I'm seriously considering using this as my main amp. Take a close look inside and you see very simple circuit design with all discrete quality components nicely laid out.
Install an IEC socket, rewire the A/C input and output section with quality binding posts and nothing to complain about. If you think about the process of amplifying an audio signal, not a lot has changed over the last 30+ years. Buconero117 has a point.
