I really like the EAD. My dvd player is the Philips963A. I still like the Philips for SACD, but on redbook cd, what first sounded like detailed and extended treble, soon became irritating (regardless of what level of upsampling I chose). Adding the EAD put a lot of "flesh" on the music--sounds more robust and three dimensional without while still retaining good detail (movie dialogue, for example is clearer). I think I paid 450 for it. I would work with the rca from your pioneer and the optical from the MF. I don't know what your budget is, but if it's under 500, I think the EAD would be a good choice (as would the CAL Alpha mentioned above), but I'm sure there are other good choices as well. Plenty of info. in the archives.
