Phil1,
I just received my APL back earlier today. I noticed an immdediate improvement. The music was more real, holographic in ways. I have listened now for about 8 hours with redbook and SACD. I will wait to comment futher on the sound. The unit now has an external toggle for turning the remote on and off. The remote serves various functions(Sony remote, I think it's funny)when I push the REC mode, I can adjust volume control, pause by pressing 1, and invert phase by pushing 6, button 4 and 5 are the filters. I have not really used them as of now. I will in the near future, and will let you know . In the DVD mode, I can change tracks with the channel up/down, or by hitting the track #. Pretty simple to use, and a GREAT time saver for my fam. More to come.
