The amp is Brand New. Box has never been opened, so there are no hours on the amp. Purchased to setup new Revel Salon II's and Voice II center. Plan changed and decided to keep Ayre monoblocks instead.Around back the No 533H is all Mark Levinson, sporting three sets of the traditional Mark Levinson hurricane style binding posts accompanied by both balanced and unbalanced connection options. The No 533H features a removable power cord as well as a 12-volt trigger and an Ethernet port.The entire casework and design of the No 533H's chassis has been focused around cooling, for it uses no fans of any kind nor sharp external heat sinks. The No 533H, like the No 433 before it, uses convection cooling.Being green is all the rage these days and the trend has not gone unnoticed by the designers at Mark Levinson, for the No 533 boasts some very impressive power consumption specs in comparison to the old No 433. For starters the No 533H's standby power draw is three Watts, down from 10. When on, the No 533H draws 130 Watts, down from the No 433's 200, making it a far more efficient and Mother Nature-friendly design. At full power, or what Mark Levinson calls one eighth power (full power is usually only needed in short bursts) across all three of the No 533H's channels, its power consumption is 715 Watts, though one can expect the figure to be far lower for extended listening, even at higher levels. Sorry no international shipping and buyer pays shipping and Paypal of 3%. Thanks for looking.
