I have a 103 running a Krell Foundation to Krell TAS to Revel F52 based surround system with JL Audio F112 sub. Using decent, non outrageous, power cords, interconnects and speaker cables. It sounds spectacular. But all the components contribute to the final result. Have ordered a ModWright Oppo 105 to replace the 103 at 8 times the cost of the 103. Won't sound 8X better however. Already have one ModWright Oppo 105 and a couple of 95s. For the price you will never find a better rig than the 103 IMHO. But the rest of the links in the chain are crucial.
