Mine is around $150K… I started with a Marantz 1040 integrated amp in 1972. I have been learning and upgrading ever since to the system I have now. All of my components are pretty new. I have finished tweaking interconnects and power cords. I have one more power cord to go. I’ve got an upgraded arm for my Linn turntable on the way. I’ll add podiums for my speakers.
Since I have all Audio Research Reference gear and could not be happier I will probably just keep them contemporary.
