Musical Fidelity A3 24 What R My Ears Telling Me?

I think that I have finally lost my mind from tweaking! I was very excited about this product when I bought it. I thought that it made a tremendous differnce with the players I was using (an Adcom & Pioneer). The Soundstage was enhanced, the music jumped from the speakers. This was indeed the Holy Grail of Upsampling DACS. The problem started when I bought a new player...the new Sony DVP-NS999ES. Now I can have SACD and pristine Redbook SACD like quality CD's through the MF DAC! The first problem is that when the Sony is turned on with the DAC on. a pop comes through the speakers which causes the DAC to downsample to nearly Real Audio quality! This is remidied by turning the DAC off, then on. The "downsampling" happens every so often when the draw is opend and closed. I thought it might be the interconnet, so I swapped out a Audio Quest for a Tara Lab and it continued to happen. OK, so I could probably live with this since the vendors from both retailers I bought these items from have never heard of this happening. I went to the MF website but there is no email address for support or questions. OK, I can live with this. Now here is the tricky part. I decided to play some CD's through the player bypassing the DAC and for Gods sake...they sound better without upsampling! The bass extension is better, the music has more "oomph" and clarity (how can that be??) and the sound is warmer. Can the DAC's be better in the Sony than the MF? Did I trick myself into believing that the MF worked to begin with? Have I completly tweaked myself out of my mind and ears? I have done countless A-B comparisons during the past 2-3 weeks and I must be honest, the CD's sound much better without the MF DAC. Any comments and opinions would be apprecitated.
