I think that having seperate circuitry and power supplies for Redbook, DVD-Audio, and SACD would make for a better design for modification than integrated circuits and power supplies. It would probably make for a more extensive mod., however, I think the end result would be better. The key is to find a modder with the skills to pull it off. I am confindent that Steve is one of the few that can do a great job modding this player.
