Your adp 330 is upgradable to dts I can't remember the name of the company but it can be done, but costly 500?.If you need to replace your Harmon kardon 80 I maybe have interest, I currently have my adp 330 hook to hk avr25 then hook to a 3channel carver amp and 2channel adcom, it sounds awesome, I really not intersted DTs right now because my dd sounds excellent thru my 4 monitor 9,s (paradigm) and 350 center.
Advice on Seperates?
I am an old Hafler fan. I have collected 7 Hafler XL-280's that produce 400 watts in mono. They will be the backbone of my dream system. I would like to begin the upgrade a piece at a time. Any suggestions on a Preamp/Processor? I currently use a Harmon Kardon AVR 80 with the seperate ADA 330P Dolby Digital Processor. I would like to add DTS and the new 6 channel (rear center) and 7 channel matrix sound in the replacement.
