I prefer the CD55 to the Wadia 850. In the sound arena, the CD55 surpasses the Wadia and has a superior volume control. By the way, the CD55 sounds better than the CD50. The build quality edge goes to the Wadia (it weighs a ton and has a better remote control). However, the CD55 also is a very high quality piece. Bottom line - for overall sound quality and value for the dollar, you won't beat the Resolution Audio CD55.
