Hi grm;
About 2 years ago I upgraded from my 840C to the 851C. Certainly no looking back. I was not unhappy with my 840C until I heard them side by side. It only took 3 cuts on a reference CD and 4 switches back and forth ( not an immediate a-b comparison) by removing the cd and hitting play that the decision was made. Big difference to my ears. As above described by adg plus to my mind more engaging musically. Don't really know how else to describe it. It also beats the hell out of my compatriots unit purchased shortly after my 851C came home. When Brian asked me what I thought of his new CD player (he had given it to me while on holidays as I was curious how much better a unit that cost a little over twice as much as the 851C would be)suffice to say my words were couched but the friendship is still strong. and he thinks it sound very good. Take this as you may at this late date of reply. Cheerio, dmg
