Arcam DV 88 vs Arcam DV 78

If I remember correctly the only difference is the progressive output on the 78 which was available on the 88P.

I also am interested and don't want to,in any manner hijack your thread.I was inteerested in the audio only (redbook) performance of these units.Again KMILLER5,hope I haven't offended.

I have the DV88 and feel that the audio performace (especially at the price) is quite good for both movies and 2 channel. I am, however, looking for that little extra that I feel isn't there and am wondering if a newer version of the Arcam is the answer.
