The DV45A and the DV47Ai use the same AUDIO D/As, etc. So if your main interest is audio, the 45A is a sensible choice. However, having heard both (stock version) side by side in a hi-res set up in a dealer's shop, the 47Ai was better overall to my ears - significantly IMO in transparency and weight across CD, DVD-A, SACD. Even if you don't really care for the video section, The 47Ai has better audio. The tough question is whether you would pay almost double for the 47Ai. The 45A is great value universal player. The 47Ai is less so.
I would look at the Philips 963 if I were you. I thought it is better for SACD. I was distinctly underwhelmed by the Pioneer's SACD section, although the DVD-A section seems to show some potential.
