I have owned mine for more than a decade and it is just a delight. The headphone amp (not mentioned) is phenomenal and a friend sold his £1k headphone amp and £1k phono stage when he bought an 850, feeling that the internal components were superior to what he had.
This will drive most loudspeakers and has a big smooth sound that is so easy to match and so, so easy to listen to all day long. Good luck with the sale.
