I am torn between purchasing a Harman Kardon DPR2005 or a Yamaha 1500/2500 (undecided again). Money is not the criteria but what I have is a Musical Fidelity 2 channel set up and now want to focus on the surround sound set up with one objective being that if I ever sell the MF gear then the step over to the AV rig wont be too painful. So I suppose I am asking which of the above is the best for 2-channel? I would really appreciate opinions from users of all 3 amps as I am struggling to choose (Wife doesn't like the Denon styling much). Current AV rig is a Sony DAVS550.
