Sennheiser HDVD 800 Headphone Amplifier with DAC for $1800

The new condition Sennheiser HDVD 800 Headphone Amplifier with DAC is now on sale for $1800 with free shipping at Amazon by Amazon actual. On the same listing, a 3rd-party seller has it for the same price, so make sure the one you buy is from Amazon actual (authorized dealer), not the marketplace seller. This may be a computer-generated price-match of the 3rd-party seller, or a general sale. It is not a lightning deal so the expiration time is unknown.
