I am retiring and thus downsizing.  Sorry, I am retaining my headphone/pre amp, but must sell my ZMA.  I bought it in June 2020 and it has operated flawlessly and is in very good shape….original price was $5695.  Offers in excess of $4,500 and strong preference for local sale in the vicinity of Westchester NY.  Otherwise buyer pays for shipping.

I am not allowed to attach images, but can send if email supplied.
