db,
What you need is a processor that can decode the new codecs of Blu-ray, they are a HUGE step forward in movie soundtracks!
Unfortunately to match the sound of your PDSD/PAV you'll be spending ~$7K plus.
I feel your pain in the combo, Madrigal really screwed everyone who bought that piece, they just let that set die on the vine. Too bad it's a really good sounding piece, as it should be for the $10K it cost new (my buddy just sold his for $1,400 a few months back, several months after sending it inb for repairs that cost $1,500)
