Lightly used with vintage Klipsch bookshelves for its entire life. Wonderful amp, perfect working condition. I’m forcing myself to sell it after upgrading. “The Marantz PM6007 amplifier transitioned from using an AKM AK4490 DAC to an ESS Technology ES9010K2M DAC in 2021 due to a factory fire at AKM.” “Units with a serial number higher than *70001 (specifically the 5th digit from the end being 7 or higher) usually contain the ESS chip.”
