My 875 has served me well for years. It drives my Definitive Mythose One, 8, Gem XL like a champ and I still enjoy listening to it everyday. But I hear so much about the Class D amp from the Elite's and has been holding back for years on purchasing one. The 875 lacks all the little techie stuff found on the SC 61, IE ipad control, airplay and android support etc. But most annoying is that when I use it with my HTPC, there's a handshaking issue everytime I turn my TV on with Windows Media playing. For a couple hundred dollars more than what I can sell the 875 for I can pick up the SC-61. Does anyone have both or have heard both side by side that are properly calibrated have feedback? The SC 61 is 125w while the Onkyo is 140watt.
